Abell 31 – Sh2-290 from my own „Sterntaucher“ observatory

In 2018 I took some images from the planetary nebula Abell 31, located in the constellation Cancer. For Hα and [OIII] I used my 10” Newtonian telescope, while I took the RGB images with the small Apo.

Data calibration and registration and the final processing was done with PixInsight. The RGB Data was upscaled to the narrowband data. The result was as follows:

The images were taken with the following equipment:

• Location: Krefeld, Germany

• Focal length [mm]: 1000 – 420
• Focal ratio: 3.9 – 6.5
• Mount: Skywatcher EQ8
• Camera: Moravian G2 8300 FW – Moravian G3 16200 FW
• Filter: Hα:[OIII] – R:G:B
• Exposure time [min]: 180:295 – 120:150:80
