ASTRO: NGC 2146
Two too brief periods of clear sky allowed me to collect luminance
data to replace poor luminance data collected in 2005. Blinking the frames I selected for use was quite interesting as it showed the frequent and rapid changes in both seeing and transparencey that occur duiring the winter season. I was able to use about 60% of the collected frames. NGC 2146 Camelopardalis Penryn, California December 2003/2010 FS-128 (ag, ST-4) ST-10XME RGB 10 minute subs (2003) M 250 @ f9.3 (ag, ST-4) ST-10XME Lum 10 minute subs (2010) NGC 2146 is a star burst galaxy still experiencing the effects of a collision or close encounter with NGC 2146a some tens of millions of years ago. NGC 2146 is classified SBa-b/P, Surface brightness is 12.8 and red shift distance is 41 Mly. |

Unfortunately, at 78 degrees it is well into my Polaris tree and thus out of reach. Sigh... 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". |

Very nice picture Glen.
