Got my Daystar Quark on friday and did a brief imaging test today .
I just dropped it into my Orion ST80 stopped down to 40mm F40 original
crappy focuser and quick and dirty manual focus so focus not spot on and seeing very average.
Had a brief play with tunning and it looked ok at default but Ill work on that as well . Put in my new ASI290 and just took a few 15sec grabs and stacked 40% .
Results are looking promising have a replacement foscuser coming for the ST80 and then I have my 102 to use as well and possibly something bigger later :D:thumbsup:

Whoooo!
That didn’t take long to arrive.
Not sure why you’d want to stop down the ST80 it should be OK with the Quark. Worst case you could add a UV-IR cut.

Pretty good start! Not much in the way of surface activity, but there were a couple of neat small proms yesterday, you need to use GONG to easily orientate the view to catch them.
Well done.
Onwards and Upwards.

Thanks
Came in a week from OPT was very quick.
Quark works best from around F30 ideally f35 to 40 there was a big increase in detail when I stopped down :D
I could see multiple little proms in the 25mm eyepiece I tried
but yes bugger all else.

Ok....
Compromise, try a 60mm aperture.
f30 should be good, and give Thant little bit more aperture = surface resolution

It was convenient to pull off the centre cap to give me a stop down lol. I intend to use the 102mm and most likely add a 127 f8/9 which will give me the ideal along with a large chip asi174
