ASTRO: Hind's Variable Nebula, a huge molecular cloud and 9 asteroids-- no waiting
Not what I had hoped for but at least its better than my last post of
the Hercules galaxy cluster with all the flat problem. Moonlight nailed this one even though it wasn't a very big moon. The one clear night I had in December also had some moon but I tried this one anyway. Lots of gradients to deal with and I'm not all that sure what was gradient and what was real as I dug really deep into the data to bring out the huge molecular cloud that T Tauri was likely born in and has no escaped. Still getting most of its light from gravitational collapse as it hasn't started fusing hydrogen yet, it isn't hot enough to give off ultra violet light and thus cause the cloud to glow the normal pink color. So it's a dirty brown in my shot though I've seen some showing it blue. My blue data was very weak so I'm lost how it could come out blue without some jiggering of the color balance. Or maybe some haze moved in and reduced my blue severely, I just don't know. I need to try again on some moonless night. Indeed, after seeing the moon problems I planned on retaking it but that was more than 2 months ago and now it is over in the part of the sky that's lousy this time of the year due to lake fog. SO I decided to process it anyway. I was shocked to find 9 asteroids in the shot, my previous record was 5. Only 8 of which are known. One is unknown, the one in the lower left corner. Some are faint, one below 20th magnitude and most of the rest nearly so. See if you can spot them all. I'll post a separate posting with them identified. Obviously after more than 2 months have passed there's no hope of recovering my discovery. That's the second that's gotten away from me. This time I could blame myself for not looking closely for one but since it was cloudy the rest of the month and the moon was out much of that time I will just blame the clouds for it getting away. Because the molecular cloud is super faint, it barely registered on my first try for this guy in 2006, I binned 3x3 to get 27 micron pixels to catch as much light as possible and gave up some resolution. 14" LX200R @ f/10, L=7x10, RGB=2x10 (needed more), 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". |
