8"SCT

ISO 500
1/6 second exposure

I went back and played with some of the shots I took last night and liked this one in particular.
This is a single shot not stacked.

Download is awesome.
Thank you very much.
I was quite happy with how clean this shot turned out to be.
I am looking at a fine focus that will mount into the eyepiece.
SCT's are notorious for being hard to fine focus.

What camera did you use? Did you stack lights, darks, and bias frames?

Do you have a Bahtinov Mask? If you are using a DSLR this mask can guarantee sharpness.....or using a laptop to view.
Great shot - especially like you got two of the moons in the frame

What camera were you using? (Full Frame or Crop Sensor) Was this a prime focus connection (meaning that the scope is using the camera as its eyepiece)? Or was it eyepiece projection in which the eyepiece is in the scope and the camera mounts on top of the eyepiece (may be with or without a lens).
I am not sure if that scope can tolerate a Full Frame camera in Prime Focus or not. I find on my 8" reflector using a 2" focuser, I get vignetting with the Full Frame camera. With a crop sensor camera, I have no vignetting.
Your scope is about a 2032mm lens and at prime focus with a full frame camera, would be the equivalence of 40X what a 50mm lens would see. And with a crop sensor (let's pick a 1.5X crop factor) it would be the equivalence of a 60X image. And then what ever cropping you apply to the image to make that even higher.
Anyway, would be interested in knowing which route this was.
Good shot.

Your question was not intended for me....and i am not trying to hyjack this thread. But here is a good link that will give you a "field of view" whether shooting solar or deep sky.....viewing or astrophotography - using a focal reducer or barlow xxx, using a full frame or crop DSLR or CCD with a number of prominent makes/models. http://www.skyatnightmagazine.com/field-view-calculator

I actually see 3 of the moons.
I had to look up Bahtinov Mask. Not sure it is needed for Sony Cameras. I can enable focus magnifier and pick a star, any star including the dim ones, and carefully focus until it is as small as possible.
I do find a coma corrector is a big help.

The mask will help you to focus the scope, with any camera attached, for a sharp focus. If you have live view or if your camera can be tethered to a laptop - there are a number of software programs - many free, that will allow you to focus your scope while using your laptop and mask.

Wow, where to start.
I was shooting with a Canon 7D with a 2 inch adapter to scope. This shot I had added a 2" 2X barlow to the mix.
It was about a 40% crop. I am attaching the uncropped version.
I use the full frame 5D Mark II from time to time but not for Jupiter. Vignetting may be occurring but it is not noticeable in a black night sky.
Thank you for the compliment and I hope this unmuddies the water.

No stacking this is a single shot.

No I do not have a Bahtinov mask.
I am planning on getting a Crayford dual speed focuser for the SCT. You use the standard focus knob for course focusing and then the Crayford for fine focus. It eliminates mirror shift and allows for a much finer focus.
I currently use my live view screen at 10x to get it as close as I can.

I thought I had all four but the 4th was too far down range to keep when I sharpened and wanted to crop a bit.
Thanks Craig.
