[ap-ug] M101 from our light polluted skies

Since you’re only highlighting the mount and modeling you won’t be needing the scope after you are finished will you? If not please put me first on the list to buy this well used scope. 😂 
Unfortunately, I, no doubt , would not be able to afford it. But keep me in mind… I keep thinking I’m going to find that gold hidden on my farm.

All I can say is that I want one!! Lol
That would be an absolutely incredible view. I would love to see that. “Dome land”, the Hortensius, Milichius, Tobias Mayer dome field must be spectacular! Apollo 11 landing site and on and on. I would be in Heaven.

Hi Jim,

You should see what this scope does when aimed at the Moon on a still night. 1000x and still not enough.

How long were the subs? Do you need a 190 point model because of the fl?  Would a smaller model, modeled around the object work as well?

Hi Astronuts,

Had a couple of clear nights last week, enough to shoot some images with our 17" Astrograph using the venerable and old STL11K (I call it the noise maker). With 9 micron pixels it's a great match for the 17" F8 scope. There is about 5 hours of image, stacked and lightly processed in MaximDL, unguided with APCC/APPM modeling. No need to guide any more even with this long focal length.

A smaller model modeled on the path of the object would definitely work fine. I chose to do a full model so I can use the pointing model to place objects on the chip. Without the pointing model I was not able to do that - thus the need for a full sky model. Actually 190 points for the full sky is basic and a bit sparse compared to what real dedicated imagers use. I probably should double that to get better accuracy.
