M33, Triangulum galaxy
Triangulum galaxy shot from Amsterdam (Bortle 7)
Data acquired from the high school observatory I work at, for the first time completely remote.
The observatory consists of a omegon 355/2845mm truss Ritchey-Chretien telescope on an eq8r-pro in a 3m ScopeDome. There are images of the dome on my profile if you're interested :)
There were some problems with guiding causing me to lose 3-4 hours of data in the end which is a shame. The flat frames of the L-filter also have very weird artifacts, forcing me to crop a large part of the image away. In the top-left corner a part of these artifacts is still visible.
Finer details:
Equipment:
ScopeDome 3m dome
Omegon 355/2845mm RC telescope
EQ8r-pro mount
0.67x reducer (1900mm effective focal length)
ZWO ASI2600MM camera
ZWO EAF
ZWO EFW (Antlia LRGB)
ZWO OAG-L + 174mm-mini guidecam
Lacerta flatbox used for flats
Software: NINA + PHD2 + GSServer + ScopeDome driver
Frames:
5x180 B
9x180 G
9x180 L
11x180 R
Processing (Siril):
RGB composition -> GraXpert gradient extraction -> SPCC -> BXT -> NXT -> Stretch
L -> GraXpert gradient extraction -> BXT -> NXT -> Stretch
LRGB composition -> Starnet star removal -> NXT on starless -> Recombine and stretch starless
