Description

This is an OSC SHO palette image of IC1795 or NGC896 in Cassiopeia, sometimes called the fish head nebula.  The molecular cloud in this region harbors a protostellar clump that may become a bright nebula in the future.

The image is composed of 9 hours of total exposure with the reduced 8” Meade ACF, including 24 x 300” exposures from 2022 with the HA/OIII dual narrowband filter, as well as 42 X300” exposures with this same ALP-T filter from 2024, plus 42 x 300” exposures from 2024 with the D2 SII/OIII dual narrowband filter.  The stars in the 2022 data were poor given backspacing issues with the  reducer, and I was able to incorporate the starless data from this session with the better data from 2024 to enhance the final image.

Let’s go fishing!
