Moon presence: None - moon not in sky
Instrument: TV-102 (102mm f/8.6 APO refractor)
Magnification: 22x, 30x, 110x, 146x, 176x, 220x
Filter(s): none
Object(s): NGC 2022
Category: Planetary nebula.
Class: 
Constellation: Ori
Data: mag 11.7  size 29" x 28"
Position: RA :  DEC :
Description:
Tonight, horrible seeing has returned, but was quite transparent.  I could 
easily see omega Aurigae and much fainter stars.  There was some wind as well.
Stars were twinkling widely near the horizon and somewhat near the zenith.

While in the area of Auriga, the TV-102 also iced the 11.7 mag NGC 2022 PN in
Orion.  The strangest thing was that the TV-102 couldn't see it at 22x nor at
30x (30mm Ultima)! Only when I slipped in the PN "killer" 8mm TV Radian (110x)
was it obviously there, right under my nose, looking like an asymmetric fuzzy 
blur that is relatively big.  Best view at 146x and noted that the PN formed a 
triangle with the 12.1 mag star GSC 714:12 and 11.7 mag star GSC 714:37.  Later 
when I looked at my chart, there is a 12.0 mag star GSC 714:101 next to the PN, but I did not note seeing it. 176x and 220x made the nebulosity show up clearer
and oval looking.  Dim gray at all magnification. No central star seen.
