The lady I bought the scope off is super clever and capable. She would have made sure the focusing tube was lined up properly.

Thank you all! I didn’t make it clear that this pic isn’t from a sub as I didn’t get that far. It’s only a 3s snap while focusing with the ASIAir. I’ve used my old SW Explorer 200P for years with this CC and mount with few issues. It’s just since using this cam.

Hi all, I’ve been using my ASI533MC with my 72mm frac with real success. Now we’re into galaxy season and I’m using a Newt. I currently have two: a SW Explorer 200P and a second-hand Altair 200 from a friend. Both are f5. With the SW I get stars that are distorted (tried to get a pic tonight of that but the clouds rolled in) and with the Altair the stars look like spaceships! See poor-quality pic. EDIT: this is a 3s snap from the ASIAir while focusing, not a guided sub. I never get that far. I’ve collimated both scopes to within an inch of their lives with an OCAL. I use the recommended spacers to make up 55mm back focus as recommended by the ZWO site. I use an all-purpose coma corrector which FLO said should be okay. To be honest I’m losing the will to live. Any ideas?

I’m still new to my ASIAir (V1) and want to know how to enter coordinates. I want to image comet 12P but am not sure if it’ll be in the database. Just to try things out, I went into SkySafari, got up the comet and tapped a star near the comet’s head. That brought up co-ords. But how do I translate them to RA and Dec to enter into the ASIAir GoTo feature? I hope I’m not being too dim. I have a learning difficulty and the obvious isn’t always obvious. 😊

Many thanks. I've worked it out. Got a few brain cells working!

Sorry if this is a stupid question, but how do I download the software on the site below? It looks very technical! I'm on W1.8. https://greatattractor.github.io/imppg/

Thank you all! 🥰

I've yet to try! Go away clouds!

Looks good! Where did you get the tubes from?
