Cave Nebula

It was an exceptionally good night for observation, so I acquired 31×4 minutes at ISO 3200 light with the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, having both the Baader UHC and the IDAS LPS D2 filter in front of the sensor. The Cave Nebula is one of the few Caldwell objects not taken from the NGC or IC catalogs. Since this was the night I deployed my home made power supply for the camera, I am very pleased with this, sort of first light image.
