In June 2021 I already took CTA 1 once with a modified EOS RP and the ASI1600.
With the new equipment, the SNR could be photographed much better.
The 450mm refractor (ASI6200MC) determines the image size. CTA 1 also I took with a 2-panel mosaic and the 800mm Newtonian and the Ha filter.
By coincidence, in the wide field next to NGC 40, there were 2 other planetary nebulae in the image that I had not noticed before.
With the help of the Aladin software I was able to identify them.
1. Kn50 (King 50) (Gaia DR3 2229266628545001984) on the left side at 11 o' clock.
The central star of Kn 50 with mag 19.3 cannot be seen in my image, which is not surprising, since I photographed with the extremely narrow dual band filter (3nm/3nm).
Surprisingly I couldn't find a single picture of the Kn 50 on the web, although this object is relatively large and bright.
2. PK 118+08.2 at 2:30 o' clock
From the PK 118+08.2 I found a long focal length image by Gary Imm
