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! 🥰

Thank you all! 🥰

Thank you!

Thank you all so much for your help. 🥰

Very many thanks. This is good advice.

I was recently told aboout ROI. O never thought about that! 'll try it once the damn clouds g away. What's IMPPG?

I've yet to try! Go away clouds!

Looks good! Where did you get the tubes from?

Hi all, I've made a pretty rough dew shield out of a yoga mat, which I also used last night to try to block an annoying LED street light - it's shielded but still bright. There seemed to be strange clouding in my images, which change a little in each sub. I wondered if there was still some light getting in and reflecting as the mat isn't black. Has anyone made a cheap but sturdy black dew shield who could give me some pointers? It's for a SW 200P. Many thanks. Alexxx

Many thanks all. I did finally get it to focus. I was rushing in as my PST is so easy. I should have used an EP first, to get the pressure tuning right and see what activity there was. I did this on an 8mm EP. It worked well. I was advised to remove the EP holder from the filter diagonal and attach the cam directly to the diagonal. This worked well although I had to pull the diagonal a little way out of its holder, which I was also advised to do. I can get focus with a 3x Barlow well now, but the exposure setting has to be pushed so far up in SharpCap that the frame rate drops down to practically nothing! I'm using USB 3.

Thanks. It was with a camera. Even visual I couldn’t see any activity. I’ve been reading many posts about not being able to achieve focus without adapters, extension tubes and even in one case, elastic bands! It’s ridiculous that my old PST performs much better. I’m very disappointed. Waiting for a reply from Tring Astro

I need advice on my Lunt LS50TH alpha B600. I tried it out yesterday and wasn’t impressed. I’m prepared to believe it’s user error! It wouldn’t focus with my ASI120MC cam. It wouldn’t even focus with the 2X Barlow. It only just focused with the 3X Barlow. There was just not enough inward travel. This is the more expensive model that’s supposed to be suitable for photography. I couldn’t see any granulation even turning the pressure tuner to its full extent both ways. I couldn’t see any prominences at all, but it could have been that the Sun was very quiet. My old Coronado PST can focus with a 2X Barlow and granulation is extremely clear. This isn’t the mind-blowing experience I was led to believe I’d have. What am I doing wrong? Alexxx

There was some horrible mess in this image and I now should start taking flats. I never had to before, with my Atik 314L+ but it's getting old. There's a bright (but shielded) LED street light which was causing reflection issues which I reduced by using a dew shield, but it wasn't complete successful. I think a nearby tree doesn't help. I've looked at so many LRGB image processing tutorials but never get star colour, or any colour, right. I've posted the original Luminance, the cleaned-up Luminance and my final image. It's awful. I couldn't get a lot of data as I was knackered. 7 X 480s L (I lost 4) and 5 x 240s each of RGB, 2 x binning. Can anyone help? Is it possible that the cloudiness around the galaxy is nebulosity?

Thank you! X

Thank you so much! Would it annoy you if I ask you any more questions I might have?

Thanks Dave. I'm still trying to find a tutorial for IMPPG that I understand! Can you help?

I've seen IMPPG but it all looks very complicated and written in quite high techie speak - for me anyway! Is there anyone who can help me create a GIF animation with this software?

Thank you. I can't see solar disk mode in AS2. I used Surface only.
