for anyone looking into this, as i did, i got the ASCOM driver for the Orion Starshoot to open, but only on SharpCap 32-bit.

I moved the covers from around the camera and focuser......and Oh No - more light!  I read up on focussers and how not to worry about the small amount of light they let in through the gap to allow the tube to go up and down.  But, the dark shots (now that he mirror end was sorted) showed me the culprit for the weird circular refractions...yep focuser leakage onto the secondary and onto the primary and back to the camera.....What to do?....Baffles Baffles...hmmm....oh flock it!? a special adhesive skirt around the focuser tube that could ride up and down with the focus? 

Er - queue brainwave!!!.  I found an old black sock, cut the foot part off, and yippee, the leg part of the sock covers the base of the focuser right up to the camera ring.  And this sock still had good elastic to hold it securely.   And another test....very very small amounts of light....but most acceptable for a budget solution! 

I really could see the gradients and rainbow patterns on my lights, and even after applying flats, darks etc....so I would suggest the loss of a sock and an old black bag, a good investment!  Astronomy is sooo romantic.

I did an overhaul of my focuser this week, added stepper motor etc.. and i did a similar trick with an old rug + a 3d printed part.

Hello

Finally i have been getting better and better results from adjusting a lot of small details. But one still remains..

I get very bad results out of Deep Sky Stacker:

130x 30sec Light, 39x Dark, 26x Flat, 36x Bias.

Comparing the same input data into Sequator i get this:

Not bad, but not perfect.
I can see that DSS actually does a better job at noise removal and sharpness etc.. But it makes the whole result very washed out and has a weird color gradient all over the place...

Suggestions is much appreciated of why DSS might cause this

just had this issue, thanks for this thread! :)
