Cool image Adam:plenty of detail on Jove and a couple of moons to boot...what's not to like :smile: I have always liked the DBK series from TIS and even though I have several cameras to work with now I just can't seem to part with my DBK21AU04, my first real astro camera and still a great performer  :waytogo:  Thanks for sharing!

 

Clear Skies,

Brian :snoopy:

Thanks Brian.  Yep, I've always been happy with the 'ole DBK.  I gotta say though, a lot of the pics from the newer generations of cameras are pretty fantastic, then again, I think the biggest jump I could make on the planetary side would be to monochrome.  That's a big step :lol:

Iv'e had my eye on this topic for a while now but i shied away from posting here because i'm fairly new to imaging but i feel like i managed to get some nice detail from my latest capture , hope you like it :) 
Shot with a 5" reflector , x2 barlow and an ASI 120 mm Cam.

The  images posted here are quite inspiring!  Amazing what can be done with a modest aperture scope.  Above is my humble offering of Jupiter captured last night.  Seeing was probably around a 3 on the Pickering scale.

 

Equipment
Atlas EQ6
AP Starfire 127 mm refractor
Mallincam SSIc -16 bit, 640 by 480 2X binned

2.5 X Luminos Barlow

Exposure time~5 milliseconds

Frame rate~ 12 FPS

Processing
150 subs out of 1500, aligned and stacked in Registax 6, as well as color balanced.  Drizzle was used in stacking this image with a factor of 0.5.
A moderate level of wavelet filtering across 6 channels was applied.

 

Nicely done! I think this may be the first Mallincam image in the thread :thinking: Like many folks I tend to think of it as a DSO system but it is, after all, video...and capable of long integration time imaging. Welcome aboard and thanks for sharing.

 

Clear Skies,

Brian :snoopy:

A very nice mage there Dan, lots of sharp detail and great color...you shouldn't have waited so long :smile: I always enjoy a good transit shot, and the shadow on the surface with the moon (Io?) sitting on the limb like a perfect little bead is a classic image. Gosh, and it didn't even require a big old 11 to 14 incher to pull it in. That image pretty much demonstrates the point of small bore imaging - you can get really cool shots with smaller aperture, so just go ahead and shoot :waytogo:

Thank you Brian.   Yes Mallicam is known for its analog video cameras.  The Solar System Imager(SSIc) is a little bit of a different animal.  It is a digital output camera, like the machine vision cameras(Flea, ZWO, Etc.).  Full frame resolution is something like 1.3 megapixals, which can be binned to s video resolution.  The specs for the camera can be found on the Mallincam website, for those who are interested.  Mine is the color version that is about 3 years old.  My experience in using it is that it has excellent sensitivity, very low noise, and good color rendition.  Frame exposure can go from 1 millisecond to 2.5 minutes.  In my experience, full frames at 16 bit color, gives a frame rate of about 7FPS.  2X binned frame size (640-480) at 8 bit color gives about 30 FPS, with my computer set up.  These frame rates are relatively slow compared to the modern offerings, but are adequate for what I do.  I do not think the camera would be ideal for people imaging with filters, although the B and W version might  do better.   A unique thing about the camera is that it has an on-board DSP, allowing you to do things like real time histogram adjustment. This is useful if you are using the camera to do video observation, or broadcast live video. I have also used it for DSO imaging on bright objects with fun results.  It works for me.

Thank you Brian ! and thanks for starting this topic , I've been following it since i first got my ASI 120 mm and seeing the wonderful results people get with small scopes really pushed me to try harder and improve , i guess you're right you CAN get great results with small scopes but you should be prepared to invest a lot of time in the processing , that image alone took me probably around 4 hours , maybe ill be faster as i improve :)

Here are a couple attempts at Jupiter using an Astro-Tech AT-111EDT telescope (111 mm or 4.37") refractor with 4X Tele Vue Powermate.  Camera is a Skyris 445C.  processed in Autostakkart, Registax, and Photoshop CC. Best 15% of 2,000 frames.  Date of the first image was January 4, 2015. Europa is on the left, and Io and Ganymede are on the right.  Date of the second capture was February 9, 2015.  From left to right, you can see Europa, Io (transiting Jupiter), Ganymede, and Callisto.  Both images were captured at sea level in Huntington Beach, CA in my backyard so seeing isn't the best... ;-)

Welcome aboard Norm and congratulations on two very fine images. I believe yours are the first images here taken with the Skyris 445C, could you please tell us a bit about its performance, like what are the ROI options and frames-per-second performance at different field settings? And I have to say that it is tough to beat a really nice refractor for this kind of work, and your AT-111EDT is quite a fine scope :smile:  I see up in your sig where it says "yes, I'm still learning" and that is true of us all. It is very gratifying to me how many folks are learning what kind of planetary images they can get from their small bore scopes...and finding that they can be very satisfying. Can't wait to see more of your work :waytogo:

This is from last night using my Nexstar 6SE (2x Barlow) and Neximage 5.  As someone new to this hobby, it's fun seeing how much Jupiter changes over a short time.  The dark, reddish, linear feature in the north temperate belt seems to have all but disappeared in the last couple of days, after persisting for quite some time.  I noticed it starting to smear in very recent images (see above).  The white clouds piling up behind the GRS are also very cool.

 

16967266397_fc6f504904_o.png

 

For this I tried the Y800 codec in iCap (previously I used RGB32).  Data transfer is much smoother, but I can't replicate the warm colours I would get using RGB32.  Seeing was good on a beautiful Seattle night (who says it's always cloudy here?!) - Jupiter looked great in the scope, even before sunset.  For this image, I stacked 35% of around 2000 frames in AS!2, before processing in Registax 6 (RGB align, wavelets, histogram) and Photoshop (colour balance).  Also managed a decent image of Saturn this morning (considering its low 23° altitude) and a dismal image of Mercury yesterday evening (a little ambitious to even try right now).

 

Alain: I love the amount of detail in your images.  They give me something to aspire to!

These days I'm trying to frame Jupiter's moons instead of just the planet its self.  They make nice "family portraits", so to speak.

 

My usual setup: C6 SCT, TV 2x barlow w/ extension (~4000mm), Canon T4i DSLR, Magic Lantern raw video

 

30 FPS, 1/30s shutter, ISO 800, 3000/4000 frames.  

 

Taken last night.  Seeing was the usual so-so.  I took this before complete darkness, hoping to nab some post-sunset steady skies.  The seeing did not seem to settle down much, so only about 6/10.

Hi,

 

This is my first post. I got a Celestron 127 SLT last month and just got a Neximage 5 webcam. Last night, I got a great shot of Jupiter (GRS and Transit). So I wanted to put it up. I also wanted to thank Jgroub for his advice on Amazon (he helped me a lot in picking the scope) and WarmWeatherGuy for his Youtube videos (I would have been lost without them.)

 

Shot taken 4/17/15 8:31pm EDT outside of Boston from my driveway. (Very Light Polluted) using Celestron 127SLT Mak and GoTo mount - Neximage 5 - Icap2.3 and processed with RegiStax 6. Used the Y800 codex.

 

Thanks,

 

Chris

Meade ETX 125 and iNova PLA.

Just a stack of 45 from 800 capture but still one of my personal best. Still trying to get the balance right between gain and rate etc.
At first I thought the black spec was a flaw on the camera but saw Io. Timing was just right! I wish the wind wasn't blowing as much...

That's another nice one, lot's of good detail there :waytogo: And I think the color balance looks fine, very natural. Y800 gives you the best data you can get from that camera, personally I never use the other available codecs even though they can be a bit easier to handle.

Hello,

 

yesterday, i tried some new captures of Jupiter. The weather was good but the atmosphere was not really good. Anyway, the results are not bad.

 

The setup : SCT 6" + barlow (1.5, 2 & 2.5x) + QHY5L-II color.

 

First of all, Ganymede, Io and of course, Jupiter (barlow 1.5x) :

 

2cd53e1d445abed7ca418dc3c4f2d491.1824x0_

 

 

Then, a close up, using barlow 2.5x (highest magnification for my SCT 6" i guess) :

 

ac62e99855b8348e47ee9cbdee4bce82.1824x0_

 

To end the work, Io passing in front of Ganymede (very small, i know) :

 

40847885658484e32c99cf0bd9a61b38.1824x0_

 

Well, that's all.

 

Have a good day and clear skies.

 

Alain

Nice work again Alain! As usual the images have nicely balanced color and good detail (despite the seeing :smile:). The top image is the best of the three in my opinion, I think the center image was pushed pretty hard. I have been working on processing for the largest scale I can get either drizzling or enlarging the base scale...and I generally end up reducing the scale in the end. It seems like only the very best images taken under very good seeing conditions and with a large number of stacked frames to handle the processing (and I mean many thousands) can take the enlarging and produce a really satisfying result. This year I cannot seem to hit this happy point :p

 

Clear Skies,

That is a very fine Jupiter with good color, lots of fine detail (look close folks), and a transit event as icing on the cake. This is also the first image, if I recall correctly, taken with an iNova camera. This is of particular interest to me because I just met Roger and Elisabeth Perie at NEAF this past weekend (Roger is the owner of iNova) and we had a nice long talk about their product line. He is a pretty darn good salesman as well as a technical innovator and I ended up walking away with one of the new NBB-MX2 cooled cameras with the Aptina MT9M034 chips, the same as the one in the ZWO ASI120 series cameras. It will give you the same zippy frame rates as the ZWO cams plus the benefit of active cooling. In addition to great planetary performance, you can shoot deep sky with this thing! I think it will be highly useful for outreach since it can crank out deep sky images of decent quality in short order, and they look sharper and far less bloated than Mallincam images. But I am particularly intrigued with the planetary imaging potential of a cooled camera with its inherently lower noise levels; many of the images I saw were nothing short of spectacular. Of course I am sure good seeing was a big contributor there as well :smile: I went with the mono version and plan to test it on lunar, planetary, and DSO targets at the first opportunity and will post appropriate images to this thread...
