Abell 35 (PK 303+40.1; Sh2-313) – VdS Remote Hakos

As a member of the VdS remote observatory group, I have the opportunity to use the VdS remote observatory in Hakos, Namibia. Members can process not only their own data but also data acquired by other users, encouraging collaboration and shared learning within the group.

This particular project was a collaboration between Karsten Möller and myself, with the final image representing a blend of both our processing styles and techniques.

The target, Abell 35, is a large and faint planetary nebula located in the constellation Hydra. It features a complex shell structure and a binary central star system, making it an intriguing object for deep imaging.

Data calibration, registration, and final image processing were all carried out in PixInsight.

The images were taken with the following equipment:

• Location: Hakos, Namibia
• Telescope: TS 12“ Newton-Astrograph
• Focal length [mm]: 1391
• Focal ratio: 4.56
• Mount: 10Micron GM3000
• Camera: Lacerta DeepSkyPro2600 (mono)
• Filter: R:G:B:[Hα]:[OIII]
• Exposure time [min]: 30:30:30:245:285
• Resolution: 0.56″/px

We also imaged Abell 35 with the Takahashi, the result was as follows:
