ASTRO: M65 and M66 Galaxies
Last night was one of those nights where you just gotta go for it: we had
some unforecast clear skies last night between monsoons of near-biblical proportion. We get hit again tomorrow :-( This time of year we can get rain and clouds for two to three weeks without any relief, so when I saw an opening last night I scrambled to get some time logged. I picked M65 and M66 because with the FOV I get with my ST10XME and my AP155EDF, it frames them both nicely. This is the first time I have shot any galaxies in a eon it seems. I actually put away the emission line filters and used my other filter wheel with the LRGB set (what's that dad?). After the rain we've had lately, I expected good transparency. Turns out to have been pretty dark, clear and the seeing was better than I expected looking at the jetstream map. I managed to log 5 exposures of 20 minutes each through my lum filter before the wispy stuff rolled through again. I decided to shoot a few darks and see what happened a bit later. When it cleared about an hour or so later, I decided to tear down, it was getting late and I was tired. So here is 100 minutes worth of luminance http://www.rdcrisp.darkhorizons.org/m65_m66_page.htm |

Hi Richard
I moved FROM Castro Valley after 20 years about 5 years ago. How can you EVER get a clear night? Summer is the worse! It finally warms up and the fog rolls in. Anyway, your shots were great...

You are right about the summers: the marine layer is tough. I end up doing Fremont Peak and some of the other mountain tops when the summer marine layer is back. The fall and spring and winter aren't too bad except for the rain. I guess I get 5-10 or so nights per month of clear skies; but obviously it varies. |

I particularly liked the detail you were able to get. I remember last spring trying to locate M65 and M66 with my 60mm. Not a very good scope, mounted on a camera tripod (the one included fell apart within 3 months). But locating them was satisfying, even though I had to verify with my starmap that the two small fuzzy dots that I saw were galaxies and not stars! I have since upgraded scopes, and if the rain in socal leaves soon (though we do need it), I will see what they look like in a 4.5" scope. Erik socalsw |

But locating them was satisfying, even Thanks, the seeing was better than average the night I took them, even though I shot them fairly early in the evening before they rose very high. The transparency was good too, we'd had about 7 days of rain/clouds preceeding it. The day or two before had been pretty windy too, so my theory is the weather swished the smog out of the valley.... |
