Planetary Nebula IsWe 1 among dust

[gorann]

This large (spanning 22 arc min) but rarely imaged and rather faint ancient planetary nebula in Perseus was discovered by Ishida and Weinberger in 1987. It also has the designations PNG 149.7-03.3 and PK 150-031. It is 1400 light years away, and has a diameter of 9 light years. If you zoom in you can see the little blue and very hot progenitor star that once created this PN.

As a bonus I accidentally caught a possible planetary nebula near the bottom edge of the image, seen as a rather small red circular object to the right of the center line. It is PN G150.1-04.5 (or IPHASX J034659.8+484900).

The rather pretty blue reflection nebula at 8 o'clock from IsWe 1 has apparently no designation.

Caught 16 Jan with my dual-RASA8 rig and ASI 2600MC cameras with IDAS NBZ filters. 186 x 5 min, so 15.5 hours. Processed in PI and PS with the new XT tools.

Comments of course welcome

Cheers, Göran
