  1. Many thanks. I've worked it out. Got a few brain cells working!
  2. 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/
  3. I was recently told aboout ROI. O never thought about that! 'll try it once the damn clouds g away. What's IMPPG?
  4. Looks good! Where did you get the tubes from?
  5. 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
  6. 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 pra
  7. 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
  8. 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 fo
  9. Is this still for sale? Can it be used for mounting a DSLR on a ball-head joint and a finder-guider? Alex
  10. 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
  11. Thank you so much! Would it annoy you if I ask you any more questions I might have?
  12. Thanks Dave. I'm still trying to find a tutorial for IMPPG that I understand! Can you help?
  13. 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?
  14. Thank you. I can't see solar disk mode in AS2. I used Surface only.
  15. I want to do a GIF movie of a succession of solar prominences captures. I've done this before but it's extremely arduous lining up all the stills to get as seamless a movie as possible, but there's always flicker etc. I process the images beforehand. Is there a GIF movie maker that lines up the images and creates a seamless movie? Alexxx
  16. What about the Heart or Pacman nebulae?
  17. Please can you recommend good OIII targets? Alexxx
  18. Thank you! I have an OIII filter but have not yet used it.
