What a bunch of cool pix you folks are posting! 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.

Great shot Paul, love that composition! What's the focal ratio on that scope?
Orion Apex, f13, 90mm x 1250mm, 1.5x piggy back barlow...Thanks, Brian

Very nice Brian! On a side note if you don't mind, how would you rate the Siebert 4X barlow? I've heard some good things about the Siebert optics, they appear anyway to be good bargains.
Glenn
Thanks Glenn! 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. My imaging case currently has the 1.75x, 4x, and Multi-1.5x to 3.5x Barlows from Siebert, and they get a lot of use...

of you!
Here is my attempt as promised, eventhough my laptop
crashed and I lost nearly 27 avi's.
Here is 1 I could save from that drive, stacked with AS!2
wavelets with Registax, nothing more.
Taken with my 6" MAk, TV x2 barlow and the DFK21 @15fps
at aprox. 4200mm FL.
Too bad all my avi's are gone, now restoring my laptop.
BTW, due to filelimit size this is a jpg version, the
other version 390kB is much nicer.

These last 2 images are very nice indeed Brian..!
Yup! Better than the image I got with my 8" taken at the same time!

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.

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?
