NGC 7635 - Bubble Nebula

The grand Bubble Nebula located in the northern constellation Cassiopeia. Remember, in Greek mythology, Cassiopeia was the wife of King Cepheus (represented by the neighboring constellation in the sky) and mother of Andromeda.
Nicknamed the Bubble Nebula because of its shape, which is created by a young, massive, super-hot star blowing an enormous bubble of material into space.

 I have been using the Optolong L-eXtreme filter for most, well... all my emission nebula photos and have been really enjoying it, but I just purchased an IDAS NB3-PM filter for SII+OIII. I was able to get only 4 hrs. using this filter on 10-20-2023 to add to the 11 hrs. of L-eXtreme data shot on 10-16 and 10-17 and then combined them into the SHO photo. I like it but it definitely needs more data using the IDAS NB3 filter.
