  1. If as you say, everything is a fuzzy blob, perhaps you are over exposing when focusing, try lowering the gain a touch
  2. On the mount in the observatory ready to go.
  3. I have an 8" RC and didn't bother measuring back focus, I had no clue where it was for my setup I just went with the tried and tested 'try it and see' method
  4. I have passed a message on to Barry at beacon hill for you. He is pretty much retired now but I do know he still does the mounts.
  5. Before I automated things that's exactly how I used to do it
  6. Very interesting thread, my QHY9 defiantly blows away from the heatsink.....quality control!!!! Anyway I have just flipped the fan around and will bang off some darks tonight.
  7. My QHY9 draws warm air from the heatsink to the outside air
  8. I had a go with it and it couldn't find my filter wheel (ascom) so uninstalled it
  9. Im sticking with the version i have now, it works for me and i have no need to upgrade. if they bring out a radical new version i will bite the bullet ( but i cant think what that upgrade would be.
  10. I wonder if you accidentally left a Lum file ticked while stacking say the Red channel Kappa Sig would see the extra pixels as outliers and remove them?....asking for a friend.
  11. I have the EQ8 and run it with encoders disabled.....no problems with SGP.
  12. I stepped into the garden at 3.30 Sunday morning and noticed Orion just rising, looked a bit higher and spotted M45, and for the first time could make it out without averted vision. The seeing must have been exceptional just then because not only could i see it directly, i could distinguish separation between the stars.
  13. It's hard to believe it's 10 years or so since we all met up at Bedford, time flies!
  14. I usually do my mosaics manually, but last week used the wizard in SGP......it worked a treat
  15. Wide and in context, and a closer view. Taken with the RC8 and TS71, bothe using the QHY9 CCD
  16. I recently gave a talk to some photography degree students (on astro photography) at the local college and they insisted I charge a fee.........so I did
  17. I have been taking darks all afternoon as it happens, -20 deg 2,3,5,15 mins 10 of each.
  18. No need for darks or bias for coloured filters......colour doesn't count in the dark!!! One size fits all, use bias for all light frames, use darks for all light frames matching exposure times, the only time you may need coloured calibration is for flats if you have dust on your filters.
  19. Yes no problem with that.
  20. Doesn't work on my laptop either, hey ho!
  21. Nope, apatrently Dec backlash is not a warranty issue.
  22. That's it the EQ8 is coming off the pier and the NEQ6 is going back on. for 2 nights in a row my imaging has ground to a halt after a meridian flip and I couldn't work out why, in the morning the scope was parked in a strange position. so last night i sat and watched......... after the flip when the mount is plate solving the mount wouldn't centre.........DEC binding!! so i left it in that position and slackened off the dec worm a tad...... great! movement again, but now it wont guide in the east - to much backlash......sod this - its coming off. What a pile of junk, it has one job to do and it comes no where near doing it.
