ASTRO: SH2-274 The Medusa Planetary Nebula
Conditions for this were awful. Clouds, fog, moon and seeing were all
against me. Took several nights over two months to get this much. This has been a horrible fall and winter for imaging. RGB was taken with nasty moonlight which was a bear to equalize. Still not quite right but I give up. Nature has it in for me or am I paranoid? Nah, that couldn't be it. Reduced to 1.5" per pixel to hide lousy seeing somewhat. At least this guy has an obvious central star. Though it certainly isn't symmetrical. Under better conditions the western side should have shown up. Just couldn't pull it through all the gunk and limited exposure time. I should go back and get more time on it if the weather ever clears (not supposed to until after first quarter moon. Spitting snow and ice pellets right now but rather warm at -7C. 14" LX200R @ f/10, L=4x10' RGB=2x10', STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

ASTRO: SH2-274 The Medusa Planetary Nebula
I imaged this object in 03 and when processed I saw the yellow.
Until your image, I thought I had not processed correctly as all other images I found did not show any yellow. Good image.

... Conditions for this were awful...... It's still a pretty cool image Rick! I'll have to put this nebula on my target's list. George N |
