NGC 7331 + Stephan's Quintet


Recommended Posts

A new scope with higher aperture and FL, urged me to try something completely different and slightly more challenging last night.

Aimed at the NGC7331 with the new Stellamira 90ED Triplet + Flattener + ASI 533MC Pro and ensured that Stephan's Quintet was in the frame as well.

I absolutely love the flexibility that the 533MC Pro and 2600MC Pro gives me, as those cameras in combination with SM 90ED and RedCat51, gives a wide range of choices on targets.

For this one, i used:


Stellamira ED90 Triplet - very impressed from this first attempt

Stellamira flattener 1x

ASI533MC Pro

AsiAir Plus

Guiding via WO Glideguide 32mm + ASI290mm mini


16 x 300 secs + 22 x 600 secs (was playing with the exposure time)

50 x darks, flats and bias


Very happy with the final result, taking in consideration that the total integration time was 5 hrs and that the seeing conditions not the best. Even the structures of the more faint galaxies are viewable.
