Bubble Nebula, M52 and NGC7538 mosaic


Recommended Posts


I had 3 reasonable nights this week and decided to get some data for this mosaic.

Here version 1 made of 2x (Ha: 25x 15min + OIII: 30x 15min).

Tak FS102 NSV @ 641mm + QSI 532WS-M1 @ -20ºC.


I will try to improve the Bubble region (there is reasonably strong OIII signal there) in version 2.

Thank you for all your kind comments ☺

I will try another approach for the bubble! I have great OIII signal for the bubble and the NGC7538. But I would like too to acquire the SII signal as soon as possible (weather permits) to process it as HST.
