Back on Dec 2 Richard Crisp posted a shot of SH2-240 (Simeis 147) in
Taurus, a super nova remnant that covers many square degrees. Far more than I can hope to cover but up in the upper right was a bright blob, LBN826-827. That was my size object so it went on my to-do list. http://www.narrowbandimaging.com/sha...omoon_page.htm On December 9 about 6 hours UT I started in on this guy. I was imaging through all my ice that gives horrid gradients but what the heck. As it was coming in I saw two asteroids on the frame. I checked the minor planet center and identified them. Next morning I calibrated and combined the images to see how bad the gradients were. They were very bad. But looking closely at them I found 2 more asteroids in the image. NEITHER were on the minor planet center's MPchecker webpage. Or so I thought. The web page defaults to mag 20 limit. Having never, even in best of conditions, found one that was fainter than this it never dawned on me to set it lower but when these didn't show up I did set it to 20.5. Nope still nothing. Then in total stupidity I set it for -21. ONE popped up and did match the position of one of my unknowns. The minor planet center says it was expected to be magnitude -20.6. Yikes! Can I go that faint though this gunk or is their estimate wacko? What about the other one? Nothing. No matter where I set the magnitude limit it wasn't there. I HAD A NEW ASTEROID! But it was cloudy the next night and it has been cloudy ever since. Now after nearly 3 weeks there's no hope of finding it again. So I almost found a new asteroid. But for now it is lost is space. I should have put out a plea for someone like Richard with his 18" to look but dummy didn't have his brain in gear. I've attached two images. The first ID's the asteroids though I left my marks faint. The three known ones are on the right, west, the unknown to the upper left of the nebula, north east. The three known ones from left to right (east to west) a 2002 PS54 mag 20.6 2006 QS55 mag 19.6 2000 SB260 mag 18.4 I measure the positions of the unknown (center of trail) at about: 12 09.25468 05h 52m 23.12" +27d 08' 58.05" The nearest asteroid the minor planet center knows about is magnitude 21.9 (I know that is beyond my limit!) that is 2.4' east and 1.9' south of this position. I've also attached the full frame without the ID info. 14" LX200R @ F/10, L=4x10', RGB=1x10' (binned 3x3), 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". |

good for you Rick
I went over there one night to find the object but didn't succeed before clouds stopped me i've not been back that's a nice shot of a cool nebula. it looks to have reflection as well as emission components. a nice job indeed pretty cool about the asteroid. they are getting tougher and tougher to find uncharted ones "Rick Johnson" wrote in message ...

I think it looks like a grumpy fish. Maybe that's because I'm grumpy
about not being able to follow up on the asteroid.

Beautiful picture. What a pitty that the weather didn't cooperate on the
minor planet search. Stefan "Rick Johnson" schrieb im Newsbeitrag ...

What's the little fuzzy thing along the right side? I thought they were interested in asteroid positions even if you have only one?? I'm not surprised that you are going down deeper than 20th magnitude. It's my understanding that there's not much out there brighter than 20th mag that has not already been sweeped up, although many are waiting for better data for establishing a definitive orbit. Whomever contributes the final observation that locks in the orbit gets to pick the name for the asteroid. In my case my name would be "CloudyWeather"! ![]() George N |

It is due to a star just out of the field per the DSS plate. The only ID I find for the little reflection nebula toward the lower left is DSH J0552.3+2653 which is just its R.A./Dec. A couple other catalogs list it the same way. No info given. I've had nothing but clouds since this was taken on the 9th (UT). I pulled an all nighter that night though it got too much ice low in the sky even before I took this shot. I had to work high most of the night. We've had light to moderate snow nearly every day since. Snowed like that today though the forecast was for none but we were to get 2" yesterday and hardly got one flake. Shows how much the weather scientists know. Snow forecast for the next three days as well then just cloudy as far as the 10 day forecast goes. But since they can't get a one day forecast right I'm not putting much faith in the 10 day one! Moon is still too bright with the snow to reflect it back up for a while yet anyway. Rick |
