I am testing to see if what is said about 9 hours being minimal time for a truly deep sky image. Collecting 9 hours in Syracuse is at least a 3 night proposition but I was able to keep just for minutes shy of 10 hours for this image. There is a definite improvement over the 6.5 hour image in brightness of the galaxies and smoothness in the background. Here is the final image and links to the previous images.

SAS Members, Come and join us at Darling Hill for our final scheduled Member’s observing session of the 2022 observing season. It looks like the weather will be excellent tonight. Clear, moonless skies, low humidity and mild temperatures. It will be chilly tonight so come prepared. See you there!
SAS Members, We’re on for tonight! Our final regularly-scheduled public observing session is on for tonight, 10/14 at Darling Hill Observatory in Tully, NY. Sunset will be at about 6:30 and the waning gibbous moon will be up around 10:00. We’ll have Jupiter and Saturn well positioned in the southeast and Mars a bit later. The temperatures have been cool at night and getting cooler, so dress warmly. Hat & gloves highly recommended. Come down and join us!

I thought it might have been from the clutch, but if that slips, it’s just a little bit from handling the mount. That mark went around the entire ring. There was marking inside the mound barrel as well. I started with around […]
