Description

27min of integral Ha exposure of immediate surroundings of Alpha Centauri made for collecting the calibration data for the aperture effects of an exceptionally bright star located in the center of the field for this particular telescope system and also for searching of possible small diffuse nebulae that might be hiding in the halo - captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope on Apr 16, 2023.


The first catch here is the PK 315-01.1 (PN LoTr 9) planetary nebula [1]:

which is even showing some hints of the internal structure after star suppression is applied (200% of the original resolution in the image below):

The other two more curious diffuse objects labeled as aCen Nebula X1 and X2 in the manually annotated version of the images are these:

Another image of "aCen Nebula X2" obtained with T1 instrument of Chilescope later under [2] and also with T5 instrument of Chilescope - under [3]:
