Sh2-263 and a small PN in Orion with RASA & Samyang 135

[gorann]

I am back at my obsy in Sweden after a month in Australia, and this is my first image from 2023. In Australia, Orion was almost straight up and back here Orion is still high enough during the first half of the night for me to give some of the jewels there a go, like Sh2-263.

Sh2-263 is a Ha emission nebula and vdB 38 on top and around Sh2-263 is a blue reflection nebula. Fortunately the NBZ filter is quite good at also picking up blue reflection and not only Oiii. While processing the image I noticed what looks like a small blue planetary nebula near the top edge of the image (at 10 o´clock from Sh2-263). Simbad has it registered as a PN candidate called PN Ga1.

65 x 5 min from my dual-RASA8 rig with ASI2600MC and IDAS NBZ (Ha+Oiii) filter, all on a Mesu 200. Processed in PI and PS including StarXT and NoiseXT of course.

Cheers, Göran
 

At the bottom is a wide field image taken with the Samyang 135 piggybacking on my dual-RASA rig while aiming at Sh2-263. I have added about 50 % RASA data to the area around Sh2-263. I particularly like the spiral of Ha emission to the right of Sh2-263. It does not appear to have any designation other than LBN857 at the top.

Thanks a lot Peter! I brought some light weight equipment  (a Canon 300mm and a Star Adventurer) last time (pre-Covid) I went to Queensland, but this time the weather reports and the hassle stopped me.
