I “see” you very well

Seeing, in astronomical terms, is most simply how well we see anything in the heavens. I includes basically 2 terms: transparency and steadiness of the air. Last night was the steadiest I have ever seen the air at the Starlight Observatory. At least for the 2 hours I was able to do some imaging. After that, it clouded up. Sigh. But this afternoon is clear, so maybe tonight will be good as well. We'll see.
Last night's target was NGC7331. That's a galaxy in the constellation of Pegasus, which is rising in the East. Today has been a busy day, so I've had time only to process the image, below, but at least one of the interesting things about this image is that it shows 6 galaxies. They will look like fuzzy stars, other than 7331, of course. I have tentatively identified them as all NGC ( New General Catalog) entries and are 7315, 7331 (of course), 7335, 7336, 7337, and 7340. Four of them are below 7331 and 7315 is to the upper left. See if you can find them. When I have more time, I'll try to give more info on them.
