Me long time, no post. I have recorded Giga Bytes of raw data since late 2016, but not found the time to process it. This is definitely a hobby for retirees, but not me yet. Here is my latest attempt at one of the many exciting fields containing overlapping OIII bubbles and fronts in the constellation of Vela. The bubbles are attributed to interstellar shocks generated by stellar winds and supernova eruptions. To me, the intricate conglomeration of bubbles and shocks throughout Vela suggest a history of multiple eruptions from multiple sources. My star chart indicates that the field of this image includes the locations of the Vela X source and the Vela SNR remnant pulsar itself (towards top left).

The image is a two-part mosaic constructed from over 20 x 20 minute sub-frames per panel and filter recorded using my Televue NP127is working at f/4.2. I set the camera binning to 2x2 to increase the sensitivity to very faint emission.
Here are the PI image solver results for this field:
Resolution: 2.099 arcsec/px
Rotation: 0.480 deg
Focal Length: 530.53 mm
Pixel size: 5.40 um
Field of view: 2d 47' 0.7" x 1d 57' 2.7"
