Singlin

Two nights ago I catured these photos with my 16" Dob and Asi 120mm camera.

Which eyepieces did you get for your astigmatism Don?

That's what I was aiming to do. I also tried to make the stars much smaller as their were too many. The shot was taken with a half moon so some gradient is present when trying to stretch too much.

Canon 5D MKIII attached to an Orion ED 80 refractor. 16 x 5min frames at iso 800.

Fantastic first light. The sharpness stands out.

Moon with Canon 5D MkIII and 10" Quattro

Two more taken with the D810 on the same night.

Left home at 22:00 last night on foot and arrived at 06:00. I had to gain quite a bit of altitude in order to have a good visual of the comet.

I also have the 10" Quattro. The stock focuser is not up to the task of Astrophotography by a long shott. I also updated it immediatly to a moonlight and stepper motor. I would advise you to get the carbon fibre version as the steel version is not great when loaded fully for Astrophotography. I had a carbon tube made for mine.

Thanks Jaspa!

After taking some images of a Comet last night I decided to slew to M101 and let the scope pay for its keep for the rest of the evening. 10 x 600s in ,R,G and B 18 x 600s in L Scope: Sywatcher Quattro 10" Mount: Mesu 200 Camera: Atik 383L Filters: Baader I will try and acquire some more data this evening.

Great explanation and demonstration

Asi 120mm hooked up to my homemade 16 inch dob. This is not in perfect focus but I was playing around with my Dob that I only use for visual. I am quite pleased with this brief attempt.

I use Pixinsight to add Ha to the red channel of my rgb image.
