Jupiter with my ED100

Hi all,

Well it wasn't shot with a huge scope...the jury on my C925 is still out, but I'm convinced that it has some problems. Anyway, I shot this image of Jupiter with my trusty Orion ED100 and a 3x Televue barlow. I enlarged the image 15%. In the lower right of the disk, close to the North Pole region you can see a dark spot. That is the disk (not shadow) of Ganymede. Considering the scope and all, I'm happy with the image.

Thats really nice for a smaller scope. I was alsways impressed what my Vixen 80mm apo could do . Even small scopes with webcams can do some really nice stuff.

Hi Paul,

It was an early start in the morning for that image I bet, and the results show it paid off.
I hope you can get your 9.25 back on track, you have taken some beautiful images with it in the past.

Clear skies,

Ed Roach

Nice going Paul!
I know that you live in Arizona, and that's an area considered great for dark skies & good seeing, but is it really true for your particular area?
Could it be that your atmospheric conditions are playing games with you and your scopes, and your 9.25 might be just fine?

Thank you for sharing, and keep it up!

Hi Paul,

That is a very impressive image from a 100mm scope or from a scope much larger than that .

Clear And Steady Skies,

Eric,

Yeah, I am really befuddled by the 9.25. I had it back to Celestron and while images are somewhat better, they still aren't nearly up to the C925 reputation. I'm not sure if it is the scope (that is my suspicion) or local seeing. I did some side by side comparisons with the 9.25 and ED100 on Saturn a few days ago. I've included the link so you can see what I mean. I have checked collimation with the webcam (I never use a diagonal for imaging) and the Polaris star images are very close to round both in and out of focus...Bob's Knobs are great!! Anyway, I am going to get a couple of buddies who are known sharp-eyed observers to come over with their C11's and help me do more side by side comparisons. If it is the scope, I'll buy another scope...if it's the local seeing, well that's another issue...

A very nice result, Paul! Didn't know your 9.25 had problems- what's wrong?

Nice job Paul.

I can't wait for a clear night to image jupiter with my 4" apo.

Hi P{aul,
Just back from a visit to the very cold New Hampshire countryside (Wolfsborough) where I got to see quite a bit of snow and very low temps (minus 20 degres wind/chill).
Your images are great. Excellent detail! Congratulations!

Paul,

Very well done. You at least have a very nice ED100. Good luck on the C9.
