Wow! That is a good Saturn image...and what a deal on that camera! So did you stack images? How are you shooting without an IR remote? Movie mode? Good work, really.

Hey...Pete and Dan have it right. There is probably nothing wrong with the scope. A cool link to see what the jet stream is doing:

The #&*@! jet stream overhead wrecks the seeing. So does looking over houses during cold weather. Jupiter is pretty low in the sky, also, which doesn't help.

Hey, not bad for the seeing conditions! Saturn is a tougher target now that the rings are closing. Good work!

StackingPosted By Steve Mathis |
I use Deep Sky Stacker for digital camera images, and I suppose it would work for digitized film images as well. It is free, and you can find it at
http://deepskystacker.free.fr
It will register and stack lights, darks, flats, etc. and save the result as a 32 bit TIFF file. You don't have dark frames to mess with. You can then open the TIFF file with PS, convert it to 8 bit, and go from there.

Stacking DSLR picsPosted By Steve Mathis |
I answered your post in CCD forum, and suggested Deep Sky Stacker for deep space images. For lunar and planetary, Registax work pretty well, and is free. You can find it at
http://www.astronomie.be/registax/html/download.html
I shoot deep space with a D70 also, and have been really happy with DSS for registering and stacking. I pretty much shoot full-rez JPEGs as well. Until I got DSS, I routinely let the camera do the noise reduction. DSS does such a good job subtracting darks, however, I have started shooting dark frames in the field, and do the subtracting later. Ideally, I guess, we should shoot in RAW mode, but for me the resulting image size and extra work later doesn't justify the increase in detail I might get. Other factors are putting the limit on detail anyway! Some of my recent D70-JPEG-stacked with DSS images are currently on the Nikon Forum if you want to take a look.
