  1. I haven't used my telescope for a long time but my son wanted to look at the moon as it was clear. This was captured in full resolution using a capture of 1000 frames using the latest version ASICap and then I used ASIVideoStack with all the default settings to produce the image.
  2. Hi, Just a thought if you are using a Windows PC there are USB power management features in power management that can be disabled. Hope you get it sorted. Craig
  3. Thank you after reading about this crater online I I think you are right. Regards, Craig
  4. Hi, Here is an image that I captured with my C11 and ZWO 224mc, I have stacked the image with AutoStakkert 3 and enhanced the image with Gimp by changing the levels. Can anyone please tell me the name of the slipped disc type Crater in the top centre of the image? Sorry if I have posted in the wrong section. Many thanks
  5. Do you know what Handset you have with the CGEM? is it a Nexstar or Nexstar+ Looking at CFM in the following location http://software.celestron.com/updates/CFM/CFM/ There is a Version PDF file that has the Nextstar+ GPS fix http://software.celestron.com/updates/CFM/CFM/Firmware_Revision_History.pdf (I cannot see the Nexstar Handset listed in the PDF) Looking on the Teamcelestron beta site I can see that the Nexstar Handset has a fix available to download, you can join for free but have to wait for an admin to authorise you to be able to read and download the Nexremote beta fixes. You can request to join TeamCelestron here http://www.teamcelestron.com/ucp.php?mode=register I hope this may help. Craig
  6. Hi, I just noticed that team celestron have two GPS updates for the nexstar HC V99.22 and nexstar+ 5.31.9102 with GPS fix. Hope it might help someone.
  7. Sorry last one, this is M42 using the mono gpcam as I cant get my ASI224 to focus.
  8. Thanks this is quite hard to do for me, steep learning curve but fun
  9. Thanks, I didn't realise how hard this is with a refractor seems so sensitive to focus.
  10. Hi, Just a quick update on the 72ed, I can get focus using the 2" Diagonal with the Altair GPCAM and the GPCAM2130M, but my ASI224MC and the Skyris 618m cannot focus. Really please with the scope, here is a quick snap of the moon using a GPCAM130m
  11. Many thanks for all your replys, more things to buy and try. Craig
  12. I have emailed Skywatcher Support and I have asked what is the correct distance for back focus for DSLR and CCD, I will update with the reply from Skywatcher.
  13. Hi, Sorry for the silly questions but I am trying to find out what the correct back focus should be for a Sky-watcher 72ed, I have searched high and low on the internet for a manual thinking this would tell me. I have a few CCD's but these have been used for planets using a CPC925, I have got a skyris 618m, ASI224mc, Alatir GPcam and a Alatir GPCAM 2 mono for guiding. I would like to try my 72ED with a ASI224MC and try some DSO imaging, when I tried to focus with the ASI I could not achieve focus. 1) Do I need a 50mm 2" extension for a DSLR and a 80mm 2" extension tube for a CCD. 2) Do I need a field flattener and a smaller extension tube if the flattener is used? 3) What would be a good CCD for imaging with a 72ed refractor? Any help or advice would be great Many thanks Craig
  14. Couldnt resist, mine is in the post for tomorrow. Thanks Martin. Cheers Craig
