I would love to see what folks with smaller aperture scopes can do while we have this great opportunity. Here is The King on Friday morning, taken with my SW100ED (4") at f/36. Seeing conditions were only average/fair, but the small refractor still gave a good account of itself. Interested in giving it a go? Good luck!

I've got a question about imaging Jupiter with a refractor; I was trying to use a 3x barlow on my 92mm TMB-92L refractor but I couldn't get enough back focus to accomplish that. Do you increase the effective focal length of your refractor with a barlow or with eyepiece projection? How high can you increase the effective focal length of your system?

Pete - With the SW100ED I use a Barlow to boost the focal length from f/9 to f/27 through f/45...this shot used a Siebert 4x Barlow for f/36. In order to reach focus with your refractor you may need a tube extension - I do. I prefer the ones from Stellarvue. Richard - This image was taken with an Imaging Source DBK21AU618 (a one shot color camera) and a Baader UV/IR cut filter.

I used a 130 mm F/11.5 Schmidt-Cassegrain telescope and a 3x barlow to capture this image on the 14th of November. The camera is a DBK21 and I used about 1700 frames. Stacking was done with Autostakkert!2, wavelets with Registax 6 and further processing with Photoshop CS2. Conditions were fair to good that night.

Thanks Brian. How do you calculate the required extension tube length for your barlow/refractor combination? Is there a formula for doing that? Pete Post Extras:       BKBrown Carpal Tunnel Reged: 08/23/09 Loc: Northern Virginia, USA Re: Small bore challenge: Jupiter w/ 6" or less [Re: lcd1080]       #5550196 - 12/02/12 11:42 AM Edit   Reply   Quote Quick Reply   Hi Pete, I am mortally certain there is a formula but I have no idea what it is and did not use it myself. The operational way to tell is to plug in your planet cam and keep racking the focuser in and out until you score focus or see an out-of-focus blob at maximum in or out travel. If you get the blob (most likely at maximum extension) you need a tube extender. You can get them from Orion, TV, AP, Stellarvue and elsewhere; I like the ET3 model from SV: http://www.stellarvue.com/adapters.html, you are looking for something that gives you about 2" extra travel. You will need a 1.25" adapter to receive your nosepiece, I find this centering adapter from Orion does a great job keeping everything tight and properly aligned: http://www.optcorp.com/product.aspx?pid=15747&kw=centering%20adapter&... Hope this helps!

Big kudos to zA and flava...magnificent work there Thx! I went back and I still did have the .avi from that capture and tried restacking it and didn't get anything better. Guess my processing hasn't really changed much in 2 yrs! . Funny thing about the video is that I have no clue just how I nailed focus. There really wasn't a feature big enough to really focus on. At least with my 8" I can find *something* to use as a reference to try and get focus. I think that is one of the problems with getting a really good image from a small bore scope on planets, it is tough to get the right focus because the target is usually too small. I did have the advantage of a dual speed crayford on my reflector. I should have a dual crayford her by Friday at least for my 8". I really hope that it will help on that scope. Not sure when my new camera will arrive though.

I really like Harry Siebert's gear, it's well made and has some of the nicest glass I have ever seen. Not everyone cares for the minimalist feel of his Barlows and eyepieces; his stuff is very light in weight compared to other equipment, but I like it.

I took 5 images from the earlier session and made an animation. Not only is Ganymede making a transit, Europa is at its max elongation and making a direction change from our perspective. Callisto is emerging from Jupiter's shadow. Widefield Animation of Jupiter and Moons You can visit Astrobin for the GIF. Thanks. Paul BTW: does anyone think the faint object moving between Io and Europa is anything other than an artifact? Starry Night did not show a smaller moon in that position. And it seems to follow an orbital path...not of a Jovian moon though...more like a comet. But, I don't think it is a comet. Weird? Edited by ToxMan (12/16/12 11:29 AM) Post Extras:       Jason H.

I have had some hot pixels showing up, especially at higher gain settings. The artifact is noticeable in red channel. Paul Hi Paul, I used to crop the hot pixel trails out when possible so that I didn't have to push the black down too much or copy paste unnatural blocks of space that can be seen because their noise/gradients don't match, but I really like a bigger outer space as a backdrop, so I finally recently started using the clone tool with a small draw tip sampling the very nearby background space, which will pretty much match any background gradient, for very natural erasing of hot pixel trails no matter how long they are. If you or anyone have any questions about that, you can PM me. Jason W.

This one was truly a picture to die for... -almost!! I have been trying to grab some good images this autumn and winter.. -but with no greater luck, due to the extremely bad weather we have been experiencing here. I have gotten some "kind of -ok" shots with both the C8 and C9,25, but nothing with the quality that I expected to get, when Jupiter was at about 55 degrees elevation. Well, I shot this image of Jupiter and Io, tonight from my balcony. As we have milder weather coming in now, the snow on my roof has been melting for a couple of days. As I was mounting the scope on the mount, a small (but obviously heavy) avalanche of snow and ice fell down on the balcony... It hit my balcony table, were I have my laptop placed when imaging.... -leaving the table completely crushed! I dont want to think about, what would have happened if that chunk of ice had hit me in the head!! I decided to go on with my imaging mission anyway, and I managed to grab one .avi before the clouds came rolling in. I used my Vixen ED 100 SF and the DBK.21.618 with a 2,5X PM. 2500 frames of 5000. Y800/Y800 codec. The image is resized to 170% in R6. The picture itself is nothing to write home about, only half decent seeing, windy (15 m/sec) and clouds coming and going... I´ll post it anyway, as it could have been my last! Next time, when imaging on my balcony, I will wear a helmet for sure!! I will go through the images that I have shot with the C8 and C9,25 this autumn/winter and post the better of them later on! Kind regards, Roger!

Actual frame rate was really slow and until I buy something more appropriate I may need to dust off my old SPC900NC webcam. Perhaps if I play around with the SSAG I can coax some more FPS out of it. This was set to capture 640x480; full frame was even slower, but still faster than 1 frame every 4 seconds, which is the best I can do on my SXV-H9 (not an SXVF - F for fast).

I really like the presentation; so what do you think of the SW Mak? Hi, Brian,thank you. I think Mak SW 127 is an amazing scope both for Planetary observations and imaging: jupiter's images were taken in no good seeing conditions but I presume that in better seeing conditions, Mak 127 is able to give stunning images. I appreciate a lot its collimation sistem and its ability to mantein collimation; the construction of the OTA is sturdy: you can feel it on the hands! great the contrast of images. I recently got an ASI1200MM: I'm waiting for a better weather to test it, and I presume that the couple Mak127-ASI120 will give good performance... The little Mak is a very good telescope: I always suggest it for beginners who are interested to Solar Sistem observations and planetary imaging.

Ganymeade, Io, and Europa got blown out a bit trying to get enough light to show Callisto. Done with an iOptron 114 (4.5")Newt and MS Lifecam Studio. About as "small bore" as it gets.
