  1. Or there's this guy Telescope Repair - SC Telescopes.com service repair. Did a great job on reviving my15 year old Celestron C11
  2. And to answer F - that screw is to stop the scope/dovetail slipping all the way out of the saddle and ending up on the floor

  5. Nik Szymanek has been writing about it the last few (4 I think) issues of Astronomy Now. Neil
  6. HI again Karen, I live just outside Marchwood. And the apps are good but a while ago I put together a little presentation to help beginners navigate their way around the night sky - I've attached it here - it may be of some use. Now all we need are some clear skies. Regards Neil NightSkyBeginners.pdf
  7. Thunder & lightning here in my bit of the New Forest
  8. I'm lucky in that I have a dome, so I just leave the kit capturing darks at the end of an observing session (or sometimes do it the following morning when ambient temp is low) Neil
  9. That fluctuation may have been caused by the cam having to work flat out to maintain the temp - what ambient were you working at, bearing in mind at best it can get to 35-40 below ambient? Regards Neil
  10. Sharpcap default to SER video files when using very short exposures. It goes back to Fits or tif or png when exposures are greater than 1sec. Also, you can change the file type in Sharpcap itself (turn off the auto button) or you can set the default file type in the sharpcap settings. Neil
  11. 12 luminance subs 11 bad pixels 10 (k)nights with clouds 9 RGB frames 8 amps of power 7 planets shining 6 wavelets altered a 5 position filter wheel 4 narrowband filters 3 element Triplet 2 stars binary 1 Crab Nebula glowing in the sky Actually just a ZWO ASI 533 - there has been so much bad weather I didn't think I'd make it any worse
  12. to me, it looks like Registax is not Debayering the image - set debayering to RGGB before stacking - or you're not capturing in the correct video format - either RAW or RGB24 - preferably RAW
  13. You might find these useful:- https://uncle-rods.blogspot.com/2011/05/getting-deforked.html https://uncle-rods.blogspot.com/2015/01/deforking-bertha.html
