I went off in search of Jupiter again this morning. Same setup as yesterday, only this time I added a 2x Barlow into the mix and actually used my DIY camera adapter to hook up the little Casio to the telescope, instead of holding it by hand. I took several 30sec – 1min, 30 sec movies and was able to keep the image on screen pretty well, I think.
Anyway, after processing in Photoshop Elements 5.0 to adjust sharpness, lighting, levels, etc., here is the result with the Barlow:
I’m pretty sure had I taken the time to collimate the scope and let it cool down properly (instead of the maybe 10 minutes I gave it) I could have gotten a sharper focus. But, I was more interested in getting camera settings nailed down and learning Registax than getting the perfect image. That will come with practice.
I also removed the Barlow and took some videos through the 9mm objective only, with the addition of a double stack filter (Moon filter and neutral density filter) to reduce the glare from Jupiter. I took a video without the filter stack and of course Jupiter was just a white ball, but I managed to snag some moons. Here is a frame from that video:
As you can see, everything is pretty much over exposed, except the moons. So, I took the stacked image of the video with the filters, layered in the above image and this is what I got after monkeying with levels, brightness, etc.:
Not too bad!
I still have a handful of videos to process from this morning so we’ll see if I get anything better. Oddly enough, on the two videos I did process this morning, I tried it two ways—I had Registax stack every frame and give me the result. Then I went back and sorted through all the frames (the Barlow image had 1800+ frames, the non-Barlow had about 300 frames) and removed the blurry ones. It took waaaaay too much effort for the result (which was that I could hardly tell a difference). In theory, if I only used the best frames, that image should have been way better than the image produced using all the crappy frames too. Right?
All that effort for nothing! I must have done something wrong. More research is needed!
