Description

Bresser AR102-XS 's collimation drives me crazy: with an artificial star it looked perfectly collimated on the whole field of the 385MC's sensor, while on the sky it looks like some stars say it is collimated while others seem to say the opposite and moreover there seems to be a difference depending on the star's color!

That aside, stars are of course rather bloated, even with the use of the FringeKiller filter, but details inside M27 are clearly there to be seen.
