M27 from PTC last year

[LT]

This was taken in PTC before my trip down south to guarantee everything worked without any fault.

Taken with Vixen ED81S + HR flattener + 1600MM @624mm F7.9
R=G=B=6x300s with only bias calibrated in PI
Autoguided with Vixen AP mount

Reprocessed again with layer mask and then the data will be deleted from HDD. Because the S/N ratio is low due to light pollution and low transparency too.
