Wow. two clear nights in a row. Transparency not too hot with the murk climbing up to about 20 degrees from the horizon.
Still had trouble seeing C17, but at least a small proportion of C18 revealed itself.

Not Seen. I checked carefully that I had identified the star field.
Altair Astro 250mm, 40mm Plossl, 51 X, 52′, West is to the 10 O’Clock.
I love this open cluster. An F111 Bomber instantly recognisable with it heading off to the North.
Still not managed to see this despite being completely alcohol free tonight. I checked carefully that I had identified the star field.
Altair Astro 250mm, 14mm Delos, 145 X, 29.8′,
West is to the 10 o’clock. A 7.5 mag star is just offset from where the core of this galaxy is. Two other brightish stars, an 8.2 mag 10 arc/min to the NE and an 8.5 mag 11 arc/sec to the West form a flat bounding triangle. The outer edges were so diffuse it was difficult to estimate a size, but it didn’t look bigger that about 3 arc/min in diameter.
Just slewed to this when it just disappeared. A quick look skywards revealed complete cloud cover 🙁
