M33
Exposures:

First light with new equipment: TS-Optics 8″ f/4 UNC Newtonian with GPU Superflat 2″ Coma Corrector, ZWO OAG, EQMOD and SESTO SENSO robotic focusing motor. Was only going to finetune and test the equipment but the clear weather persisted and I couldn’t resist capturing when looking at the subs. Unfortunately guiding wasn’t perfect due to hard wind (having problems guiding in DEC for some reason).
