NGC752 - 110927

This is a cluster in Andromeda (I like clusters) that I'd been tripping over time and again, as I wander round this area of the sky, but never got round to photographing till we unexpectedly got several clear nights in a row. Hazy nights, but stars punch their way through that more easily than nebulae.
It was taken with the M25C in the William 98 on the 900GTO mount. Guided by my old H9C which I broke immediately after this shot. Almost like the classic, drink the wine and smash the glass in the fireplace. I actually snagged the wires on the mount in moving to the next target. I have done this before so should know to avoid it.
The exposure was 25 frames of 120sec. Calibration was with masterflat and masterbias, and the processing was done in Astroart and Photoshop.
