Description

Asteroids? What??

I was actually only after a pretty picture of this area as I found IC443 in company of NGC2174 interesting and see what I could gather from it. So, dedicated the night to this region.

As we all know, life is what happens while we're making plans. In my particular case for that night this meant: you have 82 minutes, then you will be "fogged"! Therefore, I collected only half the light of what I had in mind originally.... But ok, on topic, surprise, surprise:

OK, both stars, Tejat posterior and Propus - Castor's feet - and IC443 and NGC2174 are obvious but, for more you'll need your reading glasses now ...

***SPOILER***and with a little help from the "cheating map" in the revisions section on the right, it's easier ***/SPOILER***

They are there but hard to find in the wide field. So, if you're in the mood for searching needles in a hay stack, ignore the "cheating map" in the revision section :-) and check out the 4k resulotion version. I counted some dozen in my latest attempt with the 6.5k native resolution uncompressed (at home), some may be candidates only, others are undeniable ;-)

On the other hand I could not find others that actually should be there: e.g. 2313/Aruna and 3311/Podobed.

I, however, could identify these guys below:

1. 656/Beagle

2. 263/Dresda

3. 1003/Lilofee

4. 3478/Fanale

5. 2297/ Daghestan

6. 2313/Komarov

I discovered them by checking the rejection_light frames for counting the sat trails. There were 4 brighter dots also. Zoomed in and I identified them immediately as trails. Asteroids, wow! But, so many? There were even more. So, I restacked over and over and over again, varying parameters, in order to get those trails not rejected while the sat trails and the hotpixel "clouds" origanted from dithering, would still be rejected. Finally I was lucky :-)

In the revisions section on the right you'll find the guys I could identify in close-up view. All of them belong to the asteroid belt between Mars and Jupiter. Therefore, their trails are of similar length and direction which makes it easier to find them. Note, I didn't say 'easy' ;-)

Have fun! And check out your rejection frames when aimed at the ecliptic, you may find some friends of these guys here ;-)
