  1. Thanks for the advice and ideas, I'll give the velcro a go I think. Rob
  2. I'll soon have a new scope with a carbon tube and wondered about any do's and don'ts re care of the surface. Particularly thinking about putting self adhesive cable tie bases on over a long period of time - does the adhesive mark the gloss finish? I've read cf tubes shouldn't be exposed to too much UV as it degrades the finish. Thanks, Rob
  3. Nice setup, been considering one of these so I'd be interested to see how you get on with imaging through it. Is the steel tube rigid enough? What gauge is the steel? Thanks, Rob
  4. Thanks Derrick. I generally have to keep at 300s or below because of light pollution where I live, non narrowband anyway. I'm glad to hear you think I'll be able to get repeatable performance, so many words of caution out there about the EQ8 with a long tube and big moment of inertia. I was prepared to change the OTA if things didn't go well but I have a lot of affection for my old Newt! Thanks, Rob
  5. I had some worries about putting my 40kg of 14" on an EQ8 but tonight put those to bed! Rough polar alignment, can't focus accurately due to electronics problem, wobbly mounting plate but I couldn't resist a quick test. 60s unguided at 1900mm FL, I think I'm going to like this mount
  6. Star colours are perfect in my opinion, very natural processing
  7. Just a chance it could be ice on the ccd if it changes shape between subs but I would have expected a bigger artefact
  8. Thanks for the tips, glad to know I have the correct bar. Rob
  9. OK I'm new to dovetail bars Strange though that may seem ☺ I have just took delivery of an eq8 mount and bought a Losmandy 15" type d bar for it. I have fitted the bar on and was surprised to see a gap between the mount and the bar of a few mm. Is this normal? Have I got the right bar for the mount
  10. Excellent detail, lovely. I like the second image best
  11. One of my favourite objects! I'd suggest you don't clip the black and leave the sky background 10 or 15 in RGB, maybe don't stretch quite as much. Nice capture though. Rob
  12. Yeah! I use a 2x barlow but I think many of the guiding problems I used to have were due to other things, so I should give native f6 a try again - I think with what you have described I'll buy the QHY. Rob
  13. Thanks Chris, Jake. Chris what is the f-ratio and fl of the refractor? Im using a WO72FD @f12 and can only get bright stars (mag ~7) with a 1s guiding exposure and the DMK. Rob
  14. Hi, I use the DMK for guiding at the moment but considering getting a QHY5L-II, from what I seem to be reading its more sensitive? Does anyone have any direct experience comparing the two? Thanks, Rob
  15. Just tried the weed matting, depending on what you want to block out looks like you'd need 3 layers. 3 layers blocks house lights, the moon (at the moment). I could still just about see a security light through it that came on about 50m away. Rob
