PV Cep, Gyulbudaghian's Nebula
Observing location
Tynemouth, UK
Scope: 200mm SCT at f/6.3
Camera: ASI178MM. Baader UV/IR cut
Software: Firecapture and DeepSkyStacker
200 x 5s subs

Using the nearby mag 15.1 comparison star and the equation delta mag = -2.5log(flux1/flux2), I estimate PV Cep to be mag 16.4 through this filter.

Midpoint of capture 21:30 UT, 22:30 BST

Another acquisition of Gyulbudaghian's Nebula. This time 16bit images were acquired. Took three attempts to stack the images on the computer!

* Correction: it is a 14bit output from the camera
