NGC7635+M52 & M27, Altair 183C, Bortle 4

Captured on Anglesey (Bortle 4) in the field where my caravan is sited, 27th Aug 2021, 67% waning moon. The Milky Way was visible during the capture of M27.
Celestron AVX mount, Vixen 81s refractor, 0.67x reducer/flattener, Altair 183C.
NGC7635+M52 50x60s (stack best 45). M27 90x60s (stack best 75). Gain=200, Black Level=20. 50 darks, 50 bias, 50 flats.
Processed with Astro Pixel Processor 1.083 beta2+ GIMP 2.10.
For both images, APP reported frame quality from 300 down to 100 - perhaps not such a clear night then? The tide was in around midnight, which meant a lot of moisture in the air.
Note the rich star fields of the Milky Way and the reddish/brown colour caused by the interstellar dust.

Nice captures Dave.
The Cassiopeia Nova 2021 is clearly visible between NGC7635 and M52 :)

Yep, that's it.
It's still pretty bright but (again) slowly dimming. And red too, even in Ha it's showing really red.

An interesting wide vista there. A big advantage of refractors. Just in the process of trying to get mine up and running again also for a visit to what I hope will be darker and clear skies in Wales next month. It's always more of a challenge to get everything working quickly away from the home location.

The nova was a great spot. The bright flare ups must be quite irregular - whenever a particularly large amount of matter falls onto the white dwarf. I wonder how many are 'caught' by Astromomers and how many pass by unnoticed?

Both images were captured in a field where my caravan is sited (on Anglesey, Bortle 4). I had everything trimmed down to the simplest possible configuration, used widest field of view and left the guider at home.

The Nova is down to Menno.
