Maybe there should be some kind of directions for posting for the first time. But now I know how for the next time, thanks everyone

Michael, yes my ASI533 is working. I often use the torch trick for testing if I have connection with my camera and laptop.

I’d assume you don’t actually need anymore spacers because it is an adjustable flattner.

So if I understand correctly, I need to get the backfocus of the flattner to 12,9 mm as shown in this picture below. And then add some rings to achieve a total of 67,7mm. Do i take the lenght of the flattner in account as well (in the 67,7mm)? Or just the backfocus lenght?

Thanks for the response guys, I haven’t got any form of image from the 533, maybe the backfocus is incorrect. I currently use the flat 61a where on the site the backfocus states 12,9 for use with the Zenithstar 61 which I set it too. I connect it with a 11 mm ring to a m42m-m48f adapter to the flattener to the scope. Maybe a ring to short? I will test it on a distant object today to change and correct 900SL with the screen I mean my laptop. The cameras indeed don’t have a screen. My first time here so still learning the basics of stating it.

Hi everybody I recently bought my first deepsky photography setup. It exist out of an heq5 pro I already had, the Zenithstar 61, ZWO ASI533 mc-pro, uniguide 32 and the ASI 224 mc as guide camera. last night I finally had a break in the clouds to test it out, unfortunately when I started my alignment the screen of my 533 was completely black, no stars or anything, while the star was in the center of my guidecamera’s screen. I think I might need to aline my guidescope with my Zenithstar, just like the laser pointer on my newtonian. I’m not sure if and how I can do that. Anybody knows a solution?
