  2. I think I would like to use the same mast pipe as it provides a good way of mounting the ASC and simpler than attaching it to the roll off roof. Makes it easier to take off for maintenance too. The pipe was used to carry the power cable and water cooling pipes - now it could carry air from the observatory as well as the power cable. For the air supply I would use a 3D printed adapter to enclose the pipe and provide a side-entry. I have a 40mm x 40mm x 20mm heatsink that would fit on the hot side of the Peltier TEC. The incoming air could blow through this and be ducted up and into the dome.
  3. Hi Yes. You don't have enough distance. The gpu requires 55mm, so you have only 10mm for the oag. 16mm will take you too far. Why not get one specifically designed for DSLRs? Apart from the economics, this one just works. HTH
  4. This Is my original post. I will write at length what I experienced later. Thanks ira
  5. As long as its dry and you remove the loose stuff then 2 coats of 2 pack polyurethane paint should give you 10+ years https://www.international-yachtpaint.com/en/gb/boat-paint-products/topcoat-finishes/perfection
  6. All the bells but not the DSC whistle. It is price prohibitive. Not saying more until i take receipt of it and do an out of the box. I am considering making a AZ levelling platform for it and may use an alt meter with it. However I want to do more star hopping and finding so even if I do use the above aids they may get limited use.
  7. Yes. 45 mm is inside the dslr. 10 mm is the t-ring adapter between the cc and dslr. There are some coma correctors that allow/need more than the standard 55mm distance. But I believe, these are more expensive. If you have a working oag solution, you can use it on basically any telescope. But imo, you'll get tired of swapping guiders around. Once you find a stable, functioning configuration, you probably don't want to disturb it. But take that hurdle in due course.
  8. ....and still relevant! And my pier is still there!!!
  9. I looked at the 8x40, but from what I read the 50 would be better as let's in more light. Obviously they will be heavier but the olympus got the better reviews for sure
  10. Not that easy, as I tend to maximise the exposure potential of any image I take. It would be an interesting comparison, but only if I were a gear tester or had Atacama style conditions Using one to two hours of prime-time clear skies to generate a possibly inferior ( maybe, perhaps...more than likely ?? ) image of the same object is one for the purists. Anyway... looking at my past files.... LHS.. C8 Edge QHY8 OSC 105mins exposure with light pollution filter. IDAS-D1 RHS C8 Edge QHY8 OSC 120mins exposure with Enhance ( slightly different cropping). Obviously condtions / Moon Phase / scope collimation / object altitude will be different for each photo, so not exactly a fair comparison. Hope this sheds some light. Sean.
  11. Really helps. Thank you so much. I'm pleased with the decision and hopefully they arrive tomorrow
  12. Phew... I'm Glad. I read up on so many and after ordering the praktica I had to cancel as the olympus looked so much better
  13. Thanks Mark. I'm pleased. They arrive tomorrow, but now skies are cloudy lol How did you take the photo?
  14. OK, thanks for that, will have a think Thanks Martyn
  15. Thanks Mark. still a way to go to get certain aspects right but all good fun. The stars look a little cut out but I think I can easily fix that.
  16. Well done Chris, that is far from being the very, very, very poor image that you called it. Trust me, this is a difficult target from the UK, especially when you have roof tops, no astro dark and street lighting to contend with. I think that you got a lot right here, your stars are pretty round, so guiding must have been reasonable with 5m subs. The stars also show some colour, with good separation in several of those close pairings throughout the image and the 'pillars' in the nebula are clearly seen, so as you say, it is unmistakably M16. I tried this target a couple of times from my previous home in light polluted Surrey, with decidedly mixed results and even from my now much darker Norfolk skies with a cooled mono CCD and C14 it's a real challenge, even after integrating 3.5 hours LRGB data.... (see https://www.astrobin.com/stqw75/ if interested). I know that you will get a much better version in future, but I still think that this is a more than fair starting image, poor compared to what you wanted maybe, but IMHO it is not triple 'very' poor
  17. Hope we get a break in the clouds tomorrow!
  18. Just out of the box , a great reference book. Roger
  19. Ira, it might be worth starting a new thread for this... if you can include more information as to what you plugged in where, to what board, if both boards were connected at the time, and what actually happens when you connect the handset it will help. Are you able to check the board for any obvious damage?
  20. I have the Olympus 10x50 and for the money they work very well for astro use - you may have to wait a few months for darker skies to get the best out of them - unless you stay up till the early hours - I have actually had some of my best astro moments with these binoculars.. Orion neb in particular was always outstanding.... Mark
  21. LOL - to be honest, whilst I understand the basics, a lot of what Archie took me through with the conversion of the files and using python scripts from the command line was over my head too
