I see others using the same or similar scope and having much better results. And looking at other posts today, I see there is some activity on the Sun that I can't seem to capture. I'm not sure at what exposure I should use...if I have good exposure to capture the roiling surface, is that too little for getting plumes? I know I don't have a PST but I hope to get some better results...any comments are appreciated. -------------------- Orion 80mm ED Apo Refractor 8" Classic Dob (used as Newtonian on CG5 mount) Meade 70-AZ-A 70mm Guider using PHD LS60TCaK/B600/C CG-5 Advanced GT Mount Nikon D40x with T-Adaptors Philips SPC900NC(1/4"ccd)& Quickcam 9000(1/3"CMOS) Imaging Source DMK 21AU04.AS - click for cloud prediction for Plymouth, MA. area Post Extras:       colinsk Carpal Tunnel Reged: 01/17/08 Posts: 2150 Loc: CA Re: Did I capture my first plume?

You may indeed have captured a little prom there. Can you tell me the orientation of the image? You can use Tilting Sun to find it. I just walked in and the proms are fresh in my mind. -------------------- Mahalo, Colin Kaminski Coulter 10.1" Dobsonian TV-76/Baader Film White Light LS60T/DS50/FT/BF1200 LDX-75 AT Voyager Edited by colinsk (03/09/08 04:16 PM) Post Extras:       FoxK Carpal Tunnel Reged: 11/07/07 Posts: 2661 Loc: Cape Cod, MA Re: Did I capture my first plume?

Oh well...it doesn't matter too much...I don't reall yhave the right equipment for solar pix Thanks! -------------------- Orion 80mm ED Apo Refractor 8" Classic Dob (used as Newtonian on CG5 mount) Meade 70-AZ-A 70mm Guider using PHD LS60TCaK/B600/C CG-5 Advanced GT Mount Nikon D40x with T-Adaptors Philips SPC900NC(1/4"ccd)& Quickcam 9000(1/3"CMOS) Imaging Source DMK 21AU04.AS - click for cloud prediction for Plymouth, MA. area Post Extras:       DesertRat professor emeritus Reged: 06/18/06 Posts: 661 Loc: Valley of the Sun Re: Did I capture my first plume?
