NexImage 5 -- yes or no?
      #5689153 - 02/19/13 03:58 PM

OK, I'm close to pulling the trigger on the Celestron NexImage 5, here's your chance to convince me one way or another...

My primary goal is to do some basic low-time-requirement solar system imaging, and learn the associated image processing.

I have not done astrophotography before, but have an above-average understanding of the theoretical issues (I'm currently a PhD student in physics, but I am more computational/theoretical).

I don't really have an interest in long-timescale AP.

I have a NexStar 8 SE, and live in moderately light-polluted skies...I can routinely see down to about magnitude 11-12 stars from my back yard (~12 looking more toward the east, ~11 looking more toward the west...somewhat large city to the west). So, that gives some indication of sky conditions around here.

The price on Amazon is around $160. (If I get a favorable impression from the forum, I'll shop around some before pulling the trigger.)

Also, any other accessories you'd recommend? Why would I want/not want a focal reducer?

I'll also post in the beginner AP forum to get their perspective, but would like the NexStar perspective as well.

Thanks!

Just starting out I'd opt for the old Neximage used. Cheap and easy to learn on. If you enjoy the process then there are better choices available other than the Neximage 5 for not a whole lot more dough. I've got both and can't recommend the 5.

That said, your seeing will be the final determining factor in the quality of your photos. One night of great seeing throws all the "what am I doing wrongs" right out the window.

I second the old Neximage (a used one should run you $50-$60) if you are just starting out. I've had tons of experience with it and I've been able to get some pretty decent images.

Of course, all it did was make me want more advanced imaging equipment, so be forewarned.

Here's a Jupiter pic I took with the Neximage a few months ago.

What makes the Neximage 5 worse then the Neximage? And is there another camera that is sub $200 one could get besides the Neximage 5?

The 5 is actually a better camera, here's the difference.

Neximage Resolution: VGA 640x480, Chip: .25-inch format, HAD, color CCD chip, Pixel Size: 5.6 micron square

Neximage 5 Resolution:5MP (2592 x 1944) Chip:1/2.5" format, color CMOS Sensor Pixel Size:2.2 micron square

I'm not sure if this a $100 better camera, but these are the stats.

This sounds like good advice. If you have an Astronomy club nearby maybe someone might one of each for comparison. Good luck....

There's another difference between the original Neximage and the Neximage 5. The 5 is a single exposure camera, the original is a webcam.

Tim, great shot. Can you supply the details (scope, processing, etc)? I have a 6SE and a Neximage and your results are definitely exciting.

butsam--I just bought my Neximage used from Skies Unlimited for 49 bucks. They had a second one there for $49, and it included the reducer lens. No disk, but I was able to download everything I needed along with Win7 drivers.

I'm still learning my way around the sky with my 6SE, so I haven't used it yet other than to plug it into my laptop.

Tim,
Great photo. Thanks for supplying us with some specifics of how you were able to obtain the shot. I've done pretty well at resisting the urge to cross over to the dark side (AP). But at a starting price point of less than $100.00 used I may have give in to my curiosity and venture into the dark side...

I have the original NexImage and haven't yet realized its potential. That's a great Image of Jupiter Tim. I've tried but my seeing has been aweful or the sky's been clouded over. I did get some decent captures of the Moon the other night.

The pixels for the NexImage 5 are 2.5 times smaller (in each direction so they are actually 6.25 times smaller in area) than the pixels for the original NexImage. This means you will have more pixels on your planet, or a higher resolution picture, if you use the newer camera.

Watch this video to get an idea of what to expect in terms of field of view. In the video both cameras' field of view are compared.

If you use both cameras in 640x480 mode then the field of view will be 2.5 times wider with the older camera. Having a bigger field of view is nicer for finding the planet and keeping it inside of your field of view during the minute long "movie" you will want to make to feed to RegiStax for processing. Having this wider field of view comes at the expense of having a tinier image of the planet. For this reason you will want a smaller field of view (when at 640x480). You can either use a 2.5x Barlow with the older camera or just use the newer camera. With the newer camera you also have the option of going much higher than 640x480. Then you will have a larger field of view AND higher resolution for the planet. The penalty then becomes the resulting file is much bigger and the frame rate is reduced.

I use the newer camera and use the higher resolutions to help me find the planet. Once I center the planet I drop back to 640x480 so I can maximize my frame rate. I have a CGEM and am able to keep Jupiter within the field of view (at 640x480). I don't know if this is possible with the NexStar 8SE. If not I would still want the newer camera. You could go up to 1024x768 or a little higher if needed.

This link will take you to some images (more links) that have been posted on Cloudy Nights that were taken with the NexImage 5.

Thank you!

How big is the FOV issue, if I have a 6 mm EP already? I think the FOV of the NexImage 5 was quoted at equivalent to a 5 mm EP. Would it be enough to center and focus the target in the 6 mm EP, then put on the NexImage 5, and it should appear?

All this said, I am now talking myself down, and thinking of waiting until I can get a good all-around camera such as the EOS Rebel T3, which is about double the price ($400 on Amazon) but can do a lot more...my wife brought up that she wanted a better camera when I mentioned the NexImage 5 again yesterday evening, so this may be my opportunity (once we have the savings for it)! A fair number of people on the Solar System Imaging side were recommending against NexImage and instead for a just under $300 AP-only camera...and if that is the case, I might as well just wait for a just under $400 all-around camera since I don't have a great all around camera yet...I have a decent one, but not a great one, and no DSLR. Any thoughts on how that would compare?

If you watch the video about how to calculate your field of view you will see that you need a camera with tiny pixels for imaging the planets. You also want a camera that takes 30 to 50 frames per second. A DSLR camera doesn't have small enough pixels so you would need to use a 2x to 4x Barlow. You would be adding a couple pounds of payload hanging way out on the back of your NexStar 8SE. A DSLR camera would be far from ideal for imaging the planets. If you do decide to go that way I would look for one that would allow you to select a 640x480 region at high frame rate, if they even make such a camera. If you are taking 5 to 10 megapixel images you will find that 99% of the pixels are empty and your planet only uses 1% of the pixels.

The NexStar 8SE mount does not allow long exposure photography. One problem is that it doesn't have a wedge. This web page shows why you want a wedge.

If you open up the NexImage 5 camera to the full 2592 x 1944 mode you shouldn't have much of a problem finding your planet. Then you can center the planet and drop down to 640x480. The idea of using a 6 mm eyepiece to focus and then insert the camera might work. I often use the sync mode on a nearby star. I use the nearby star to focus the camera using a Bahtinov mask. Then I have to find the planet with just the camera. That way I know I have perfect focus.

I can find it easy to believe that people from the Solar System Imaging forum are against the NexImage camera. They all have the ASI120MC camera or the $500 Imaging Source cameras. I don't recall seeing very many pictures of planets taken with a DSLR. Perhaps it is useful for Moon shots.

This link I provided shows you what you can do with the NexImage 5. To me, Celestron has made the ideal camera for planetary imaging for under $200.

I would concur with Steve's assessment of the NI5 above. I think that it's a good camera, a significant upgrade from the original NexImage, and a good value under $200. In that sense I think it's the best new entry-level camera at the price.

Being who we are, astrophotographers soon desire more from their equipment and so the passionate imager will move on to the next stage such as the ASI120MM, the Flea3, etc., with the attendant filter wheels and related requirements. That is another category of imager, that I would consider intermediate. The NI5 is not really for the intermediates. You need to decide at what level you will be working and what you can afford. That will guide your decision.

Either way, you are living in the golden age of planetary imaging! Enjoy!

Great images and advice, all; thank you much! Looks like the NexImage 5 can really do a lot of cool things I appreciate all of the tips!!! It's hard to see the NexImage 5 in action...frequently they talk about the original NexImage, and searches produce a mix (with far less NexImage 5 since it's relatively new still). I appreciate it greatly!

k; I bit the bullet and decided on the NexImage 5. Part of the driving factor was that I could pick it up for $120 in used (like new) condition, still in the original packaging and unopened. I figured for an extra $40-$60 (beyond the price of a used original NexImage) the added benefits of the NexImage 5 are probably worth it, and the NexImage 5 will probably have better resale value if I later want more. I'll keep you all posted! Thank you for the great help...love this forum!

Thanks all!

For people wanting more details on NexImage v. NexImage 5 at least, here's a few details that I've found online while researching and comparing (I can't vouch for the accuracy at this point, but I am assuming it is all true):

* NexImage pixel size is 5 microns, for NexImage 5 it is 2.2 microns. The FOV is a bit larger for the NexImage 5 as well (although that isn't so critical for planetary imaging...but it may make it easier to initially find the planet).
* Sensitivity is about the same (although Celestron's webpage for the original NexImage doesn't give a precise figure, making it difficult to compare). For the 5, the sensitivity at 550 nm is 0.53 V/(lux*s).
* Original NexImage is similar to the semi-famous Philips ToUCam. (Not sure what the 5 compares to in this respect, though.)
* Original NexImage is roughly comparable to a 5 mm EP; NexImage 5 is roughly comparable to a 7 mm EP.
* NexImage 5 has variable integration time from 1/10000 s to 30 s (but you need to update firmware to take full advantage of this range -- see Celestron's website). You probably don't want to go much higher than 30 s integration time with the Alt-Az mount anyway, I have read in many places online. I believe the original NexImage doesn't have as wide a range on integration time, but I couldn't get definitive numbers online.
* NexImage 5 frame rate is up to about 5 fps at highest resolution, and up to 52 fps at lowest resolution. (Again, not sure how this compares directly, but the manual implies the original NexImage could at least support 30 fps.) Naively, to me, this means you should find the planet and center it at highest resolution, then switch to lower resolution for easier focusing. (The lowest resolution is 640x480, equal to the resolution of the original NexImage, but the pixel spacing is about 2x tighter.)
* NexImage 5 appears to support 2x2 and 4x4 pixel binning. Not sure how useful this is for planetary imaging yet, but I think this could help with either or both noise reduction and low-light. This might turn out to not be a useful feature, though, since you would probably rather have the middle 640x480 pixels all active than bin groups of 2x2 and 4x4, since the planets aren't going to take up more than the 640x480 pixels most likely on the screen.
* For NexImage 5: upgrade the firmware immediately upon receiving the device. See Celestron's FAQs for the device here for the details: http://www.celestron.com/c3/support3/index.php?_m=knowledgebase&_a=viewar...

* There are better cameras out there than either of these two; the primary tradeoff is cost v. camera quality. For the price and relative simplicity, they appear to be a great deal for the complete newbie, especially if planetary imaging is your main interest and/or you have an Alt-Az mount (so longer exposures are not even an option without upgrading the mount also).

More to come once it arrives and the requisite induced clouds dissipate! My apologies to my astronomical friends in Ohio....

That is some good information about the Neximage 5. I got the Neximage 5 as a surprise late Valentine's Day gift from the wife. I have yet to use it as I have been covered in clouds for the past week or so. From what I have seen of it so far, its basically a modified webcam that the housing is made to work for astrophotography. I don't see it being used on DSOs but that isn't what it is designed to do. It is designed for lunar and planetary astrophotography.

Here is a pic of a piece of a shingle from about a block away through a window and very overcast skies..

I've only had 1 clear night so far, under Poor sky conditions, but I'm already impressed I hope it serves you well! Assuming you have an 8SE (although procedure should be similar regardless), I found it was best to start with 25 mm EP and center, then go to 13 mm EP and center, then put in the NexImage 5 at full resolution, then center the fuzzy disc. Reduce resolution gradually, then focus (you can focus before centering and reducing resolution--just keep in mind the frame rate at full resolution is 5 fps, so it may take 1/5 a second to show the results of your new focus at full resolution; at lower resolution the fps is a lot higher, and the pixel spacing is still the same so you still get the same level of detail -- it just reduces the field of view). If your EPs are like mine, you *will* have to refocus significantly -- you are not doing anything wrong, don't worry.

You should familiarize yourself with the NexImage 5's iCap program before going out, especially if you are somewhere where it is cold this time of year. Find the Gain setting in particular -- it is the most important one. Also, figure out how to change resolutions and frame rates. You will want highest resolution initially to acquire the object, then lower resolutions as you center the object so you can get higher frame rates. For planets (especially Jupiter), you want to collect several fps since it rotates so rapidly.

Also, if you are itching for something to do during the day, here are 3 things I recommend (or rather, wish I did prior to my first session, and will do this Saturday)...they aren't critical, but they may help you tweak things a bit. None of them are necessary. In order of importance:
(1) Try determining the correct orientation for the NexImage 5. I put it in at an angle (unknowingly), which meant a minor inconvenience when centering on the CMOS sensor...that is, when I hit "left" the planet moved up & left on the sensor; when I hit "down" the planet moved down & left on the sensor; etc. It will be slightly more intuitive if you note the sensor orientation that allows for more intuitive remote control.
(2) Try looking at something far-off but with color in your area. Using the NexImage 5 with iCap, tweak the color settings until something that you know is white looks white, and likewise for other known colors. (My first night's video had a slight yellow tinge to it...it wasn't horrid, but it was noticeable on closer inspection. The iCap software lets you tweak the gain for each color separately as well as overall gain, so I just need to tweak those settings a bit. This is something you can do during the day while waiting for that clear, dark sky.)
(3) This is *very* minor, but you might want to try the computer-controlled remote. I haven't tried it yet, but will on Saturday. The advantage is somewhat reduced vibrations since you don't have to press the remote's arrows, which can cause some small but noticeable vibrations. This isn't critical, nor even strictly necessary (the vibrations dampen out in a few seconds at worst), but it might be something to try if you have the inclination...you need a laptop out there anyway.

Most of all, I wish you clear skies!

Also, something that will help is an electric focuser. It will keep the vibrations down by not having to touch the focus knob. You can build one for the 6/8SE for about $30 or so. You can buy the JMI version version, but it's about $200.

All this talk about the NI5 makes me wish the skies would clear up so I can give mine a try. So far, I have a pic of a shingle.

Well, got the NI5 yesterday and like many comments on a few other threads, it doesn't work on my laptop. Even though my processor exceeds the minimum requirements, I have read threads here and other forums that state it will not work with an AMD processor like mine. Tried all the patches and fixes suggested except one. HandyAvi can be used, but after the trial period it's $40.00. Contrary to others experience, Celestron support has been great. Attentive and really trying to figure this out. The engineers are involved now and they have been in constant contact with me. My fingers are crossed.

Hi Chaz,

Just a random and ignorant shot in the dark, but have you tried using your Neximage 5 with any alternative software such as "Amcap" (used for the old Neximage webcam), or either of its derivatives, Sharpcap or Craterlet: all of which are free downloads ?

Best regards,
Tel

No I haven't Tel. You are the first to suggest that. Are they on Cnet? And thanks in advance even if they don't work.

Tel! Downloaded Sharpcap as you suggested. It is definitely recognizing the NI5 and appears to be sending images but I'm stuck inside because of bad weather....frustrated but hopeful. Thanks.

Glad you have a potential solution! I didn't realize that about the AMD versus Intel...my laptop is an Intel i5 mobile processor with a 1 GB video card, so I didn't notice processing issues. I hope Sharpcap allows you to get some images from this nice camera! Does it allow you to change resolution, frame rate, exposure length (from 1/10000 to 30 s), and gain (both overall and per-color)? Also, did you upgrade the actual camera's firmware? (You actually need to plug the camera into the PC and go through Celestron's update process.)

Celestron support never mentioned that and I do not see any firmware updates for the NI5 on their website. I have been on the phone with them 4 times since delivery and firmware updates were never discussed.

Chaz, check out wxAstrocapture, I bet it works perfect with the NI5. It's what I use with the old Neximage cam.

Hi Chaz,

I'm glad to hear that at least your NI5 is being recognised by Sharpcap ! Equally so as Tim has proposed, wxAstroCapature is another very popular piece of software which you might find compatible and indeed superior to those packages I suggested.

There is however one caveat: at least I think there's the possibility of one. Therefore I strongly advise you to seek the truth of my conjecture.

I believe one of the features of the new NI5 over the older NI, is that it will permit up to 60 frames/second without any compression, whereas the older NI was limited to 30 f/s and was more at home operating at a lower rate to avoid any such compression. In other words, it was the software (Amcap?) that limited the NI's performance; NOT the (web)camera itself.

So saying, it is my belief that the new NI5 allows the higher rate (60 f/s), by its OWN design and is NOT limited by the any compatible, (of Celestron origin or otherwise), software. (On the other hand, the installation of the Celestron package may indeed be necessary to achieve this high rate).

Truth is that I just don't know and therefore I might well be talking utter nonsense here, but if you do decide to go the Amcap, Sharpcap, Craterlet or wxAstroCapture route with your NI5 and abandon the use of its factory software, I think you should seek confirmation that the aforementioned software packages permit an uncompressed 60 f/s download of your subframes.



Best regards,
Tel

I don't think the firmware updates are required just to get it to work (although I never tried without), but you should update the firmware as well -- at a minimum, it gives you more options for shutter speed; I don't know what else was changed. Here's a link with download and instructions:

I was able to download it. It might be your virus scanner blocking it.

OK. Well I took the scope outside (127 SLT) let her sit for a bit and hooked up the NI5. I used sharpcap as suggested by Tel. The firmware update just would not work, error code. However, it was 1300 here on Long Island so I aimed at a neighbors roof. I saw someone else post a pic of someone else's roof. A little tweaking and there it was, a shingle. Now I did not let it sit for long so the image was wavy as expected due to temperature change between house and outside BUT the cam did finally work. Next step is to become more proficient with the "Align" features, the tracking of the scope and the bells and whistles of sharpcap and we might be good to go. Clear night tomorrow night hopefully. Thank you to everybody and I will follow up, perhaps on a new thread.

Hi Chaz,

Just a note to say that I did a little checking tonight and can say, (as you probably already know), that Sharpcap will indeed support 60 frames/minute, which is the rate, I believe, the NI5 is ideally designed to deliver.

As to the quality, however, (i.e. whether any compression takes place as a result of using Sharpcap as opposed to the Celestron software), is of course something you'll have to establish.

As it stands though, it looks as if Sharpcap will at least give you working software from which to work.

Wishing you all success and please keep us posted on your progress,

Best regards,
Tel

Just got a Neximage 5 for $129 new ebay....Im new at this and have recently purchased a Nexstar 8SE OTA and an EQ5 advanced GT mount to put it on....have taken a few shots with my Nikon d300s on a t2 but wanted something to give some better sharper picsand all the reviews ive read and watched pointed to the NI 5 for my budget...

Congratulations on getting that camera at that price. I've taken some really nice pictures with it and seen even better pictures taken by other people with it. The C8 is a good scope for planetary imaging. Unfortunately right now Mars and Jupiter are gone for a while and Saturn is starting to fade away. I would try to get Saturn while you can. Jupiter will be available in the morning starting around September/October.

Visit the Solar System Imaging & Processing forum for tips on how to get good pictures and to upload your pictures there for us to see.
