This is the best image that came from my Feb 15 encounter with Jupiter. It's also one of my best to date. I captured a moon transiting the face along with its shadow and another moon further out. This shot is 8th in a series of 9 I captured that night. At first I thought the moon shadow was coming from another moon not in frame but the relationship of the transiting moon and the shadow remained the same throughout the series as the moon tracked from left to right. If the shadow came from another moon, that relationship would not have remained constant.

Beautiful cloud detail as well.
Outstanding stack. Well done!

Thanks so much Alugshutterbug. I do appreciate your comments.

Really nice image! I've done some web cam imaging, so understand the challenges. Mine never came out very well....!

Thanks for the spectacular image. Wished I could do that.

I'm all for people posting astronomical images that they have taken but I fail to understand why some choose not to exhibit any details. Is this done with a dslr?, point and shoot?, webcam?, or dedicated CCD. Scope details would be useful too. I have a 300mm f/5 Newtonian telescope and a QHY5P camera but this thread offers me no incentive or information which I can usefully apply. Please don't get me wrong, I love the pic but the lack of "exif detail" spoils it for me. Keep posting but please supply us with some detail. Cheers.

As usual another great shot NorthCoast.

Sorry about that pixelsaurus. I've detailed the process a little with other photos I've posted to this forum. I neglected to do so with this image but all you have to do is ask. Happy to share :)
My optical train consists of an ASI120mm monochrome webcam attached to a manual LRGB filter wheel attached to a 4X Powermate attached to an Explore Scientific ED127mm f7.5 refractor...a relatively small telescope but I've been able to get some nice images with it. I take three monochrome .avi sequences, one through the red filter, one through the green filter, one through the blue filter. For Jupiter I've been using 50seconds per sequence. The frame rate depends on exposure settings. Gain and gamma also figure into the mix. I adjust on the fly so to speak to optimize the picture I'm seeing on my laptop. In descent seeing conditions a typical 50 second exposure gives me about 3900 frames in the red and green, 3000 frames in the blue due to longer exposure time. Once I have those 3 .avi sequences, I crop them using a free program called "Castrator." That gives me a nearly full frame target to take into Registax for aligning, stacking and wavelets application. What I end up with are three .bmp images, one from each filter. I use Photoshop to merge them into an RGB image. From there it's just a few tweaks to lighting and contrast and I'm done. Hope that helps. I've attached a picture of my telescope with an eyepiece installed. If you can zoom in on the picture at all, note the moon sitting just at the end of the OTA. Next time I set up for photography I'll take a picture of the optical train with the webcam installed.

Thanks dlmorris. I appreciate your looking and your comments. I know what you mean. My first attempts with the web cam were terrible. Trying to get the three files to merge properly in photoshop was a challenge. That almost made me give up and use a color web cam. Finally figured out photoshop though and I've gotten more efficient with the process. I keep surprising myself with the images my little telescope produces.

I can't wait to see the Camera setup.
