  1. Great capture! Too bad about the lost 2 hours, but 7 hours is still very decent. Looks great in this wide field view. Pieter
  2. Thanks all for the nice comments! Thank you! The scope is based on a 250 mm f/4 premium grade mirror, all other components are custom designed/made parts. I have been very happy with it! There are some pictures of the design and build here: https://pietervandevelde.smugmug.com/Pics/Deepsky-Equipment/
  3. Hi all, Last week I've put together some of my data made the last couple of months to compose this bi-colour image of M27. Quite tricky to proces due to the high dynamic range of the object, quite a pain to tease out the faint outer details without making the image look to forced. I started the processing job from scratch a couple of times, but settled with this version for now. The h-alpha data was acquired from my heavily light polluted backyard, the o3 data I acquired during an astro holiday in Southern France (Provence) under pitch black skies late August. Thanks for checking them out. Regards, Pieter Some details of my gear: Scope: 10" f/3.8 homebuilt Astrograph with 3" Wynne corrector CMOS: ASI-1600 MM Cool (-10°C) Filter: Astrodon 5nm h-alpha / Baader 4,5nm o3 Exposure: 24 hours in 5min subframes (15 hrs h-alpha / 9 hours o3) Mount: Mesu200
  4. Very nice! The joys of working remote, spending hours and hours on these faint fuzzies.
  5. Great stuff Maurice, those are indeed a lot of stars... . Impressive also the speed of this setup, to go so deep after 6 hours... And you even took 2 panels in that time. Pieter
  6. Very nice Olly. Always interesting to go after these unusual faint fuzzies... Pieter
  7. Indeed, you read my mind. The region next to this was imaged by Lorenzo Comolli and there are extremely faint traces O3 present in the whole area. http://www.astrosurf.com/comolli/d207.htm He focused on the G82.2+5.3 supernova remnant in DWB145 just besides my frame. I suspect there is something very interesting to see in O3 in the bottom left part of my picture. Something to try my 4.5nm O3 baader filter on. Pieter
  8. Great! Very nice and subtle. Pieter
  9. Thanks. You are forgiven. That does not go for the senior citizen who ran me off the road.
  10. Thank you! LeDu2 is right here; it is not very obvious in Aladin, this is the outline of my image. Regards, Pieter
  11. Hello all, Finally found some time to make another astrophoto (was 5 months ago...). I sustained a pretty bad cycling accident in February and was only able to carry my equipment outside again about 3 weeks ago. Great to be able to make an image again. This one was on my bucket list for several years and I have spent 20 hours on it the last couple of days. It's a 2 panel mosaic of a very faint and rarely imaged patch of nebulosity next to DWB145 in Cygnus. Thanks to Nicolas Outters for the inspiration! Scope: 10" f/3.8 homebuilt Astrograph with 3" Wynne corrector CMOS: ASI-1600 MM Cool (-15°C) Filter: Astrodon 5nm h-alpha Exposure: 20 hours in 5min subframes (2 panel mosaic) Mount: Mesu200 Thanks for checking it out, Pieter
  12. Always great to see nice B/W images like this. This is a very handy reference image to pick some potential new targets from! Pieter
  13. Very nice, I really like b/w images like this. Pieter
  14. Very nice, I'm impressed you got so many in a single night! Pieter
  15. Very nice! Was there any sign of the nebulosity in the lum channel? Pieter
