Pitch Black Skies

I was. I moved the rotator into the back focus.

Hi, I can confirm that they fit fine 🙂

Peter, that's a great idea. Thank you for your help. I need some time to figure out the backspacing but I'm sure this will work. Alan

@whipdry To use your method I will need an adapter that is m63 female to m42/T2 male. I don't know if it's just me but I just can't seem to find one.

Hi Peter, well spotted. And yes your right, it does indeed have an m63 male thread there. However it increases the backspacing from 55mm to 63.3mm. I meet my 55mm with a 10mm and 16.5mm extension. I've come up with another solution to incorporate an m48 rotator into the backspacing. What do you think? I should mention that there's an EFW between the camera and the 10mm extension.

Still facing this unfortunate issue. Really stumped on what I should do. I could remove the rotator but rotating the tube in the rings isn't really ideal, and I don't think I should have to. Surely there's a way.

Anyone?

Can anyone help with this? I really don't know what to do. After adding a WO camera rotator and the dedicated TS x0.8 reducer into my imaging train, I can't perform an Autofocus routine on my ASIair. There simply isn't enough room. The focus position leaves 5mm of inward focuser travel. The Autofocus closes this gap. I need a few more mm. Is this normal? Surely I should be able to incorporate a rotator for image framing. I could solve it by removing the WO rotator but that means I will need to rotate the tube in the rings for image framing, plus this will cause an off balance. I found another possible solution of adding an M48 Artesky rotator into the backspacing, but now I can't find a 15mm m48 extension that is female to female to do this. The yellow arrow shows the focus position and the 5mm gap left of inward travel.

Thanks, 5mm does sound like too much for it to be moving. It's already manually focused at that point so only need minor adjustments. I do everything through the ASIair app. I will connect the eaf to my laptop to make sure all internal settings are correct. Maybe there's a driver update.

~5mm.

No they're needed for the backfocus.

Nope, tried it. The reducer hits the face of the focuser and I get an error message.

I've hit an obstacle on my TS 80mm F6. There isn't enough inward focus for my EAF (electronic automatic focuser) to perform an AF (autofocus) routine. I could solve it by removing the CAA (cameras angle adjuster) but I am then stuck with one fov as everything is threaded together. Any suggestions? Should I swap the .8 reducer for a x1 flattener instead? Is there a rotator that can thread into the backspacing? The focus position is a ~5mm gap where the yellow arrow is pointed.

Excellent work 👏 well done 👏 I've heard nothing but good things about the Samyang 135. You will be one to watch out for in the future I think, very impressive.
