π The Triangulum Galaxy, M33 is a beautiful sight. 2.73 million light years from earth it's the third largest galaxy visible. I took this photo using LRGB and Ha filters for about 20 hours.

πW63 is a supernova remnant located in Cygnus. This narrowband image shows Ha, OIII and SII emissions. This object is large and very faint, I needed more than 70 hours of exposure time overall.

π SH2-91 looks very similar to the Veil Nebulae in Cygnus Loop, that's why some call it "The other Veil". However it's much fainter. Took this from the remote site Trevinca Skies in Spain.
