The seeing was fair but it was very hazy (also makes focusing difficult as well) which has reduced contrast. I think the prom extends further than my image but the edges have been washed out. -------------------- Best regards Paul Robertson My Gallery Post Extras:       cuwohler Carpal Tunnel Reged: 10/24/08 Posts: 1986 Loc: N 53.1 E 10.0 Re: SW prom [Re: pjr200]       #3318079 - 09/06/09 07:20 AM Edit   Reply   Quote Quick Reply   Great shot, Paul! Because I think that your seeing could be similar to mine today, I wonder what exposure time you use. I use 1/30 or 1/38 sec. -------------------- Cai-Uso http://www.cuwohler.de/ Post Extras:       Ralph Marantino Postmaster Reged: 05/01/05 Posts: 6331 Loc: Old Bridge, New Jersey Re: SW prom [Re: cuwohler]       #3318081 - 09/06/09 07:25 AM Edit   Reply   Quote Quick Reply   Thanks Paul cloudy here to ther East -------------------- Lunt H-alpha LS100THa/B3400 Rockland Astronomy Club Member BAA Solar Section Central Appalachian Astronomy Club Astronomical League DSPST,PST & 70mm Coronado Cal K telescope.2.2A Zeiss 2 inch prism diagonal&Zeiss Zoom EP 2inch APM Herschel Wedge in a 94mm F7 Brandon 14.5 inch f4.2 Starmaster Dob(Zambuto mirror) TeleView Genisis SDF with 1000 Oaks Glass filter Zeiss 63mm f13.5 refractor 1000 Oaks Glass filter Itty Bitty Solar Radio Telescope.

There was so little contrast between the proms and surrounding space that I had to reduce the gamma to about 40. I tried a 2x barlow lense on the end of the dmk it seemed to work well with 1/38sec exposure times with no gain. -------------------- Best regards Paul Robertson My Gallery Post Extras:       marktownley Carpal Tunnel Reged: 08/19/08 Posts: 2267 Loc: West Midlands, UK Re: SW prom [Re: pjr200]       #3318491 - 09/06/09 12:57 PM Edit   Reply   Quote Quick Reply   Nice capture paul. Interesting reading about how you adjust the gamma, i've just left it as is - till now... So, some clear skies and then a little experiment me thinks Post Extras:       chuck p super member Reged: 07/18/06 Posts: 148 Loc: Cape Coral, Florida Re: SW prom [Re: marktownley]       #3318499 - 09/06/09 01:01 PM Edit   Reply   Quote Quick Reply   Excellent detail Paul! -------------------- Criterion rv-6 (original owner 1976) 12" f/5 Dob (Astrosystem) 127 Orion Skyview Pro 8" f/5 Orion newt WO FLT110 f/7 eq6 mount Canon Rebel xt Phillips spc900 webcam Orion Starshoot 1 and 2 Orion 80mm ed Orion 72mm Eon Lunt 60mm double stack Post Extras:       pjr200 Carpal Tunnel Reged: 08/29/07 Posts: 2406 Loc: Staffordshire, UK Re: SW prom [Re: chuck p]       #3318894 - 09/06/09 05:26 PM Edit   Reply   Quote Quick Reply   Thanks Mark and Chuck -------------------- Best regards Paul Robertson My Gallery Post Extras:       darkstar528 Postmaster Reged: 03/06/07 Posts: 6798 Loc: Hodgenville, Kentucky, USA Re: SW prom [Re: pjr200]       #3319781 - 09/07/09 07:47 AM Edit   Reply   Quote Quick Reply   Wow, awesome capture!!!!!!!! -------------------- Blue skies, Stephen "Darkstar" Ames PST(#96038), VIXEN 8-24mm,CEMAX 2x Barlow, Thousand Oaks White Light Filter and a Meade Elec EP CFI, CFII, MEI, working on EIEIO!
