I am happy to share with the community my biggest deep sky astrophotography project to date - 211 hours of exposure time on the M33 galaxy. I started this project in August 2023. By the end of September 2023, I had 80 hours of exposure time to process, and I noticed a few interesting structures that I paid some extra attention to in my 22-page observation report that I was working on in this Google Document. While imaging M33, I practiced different processing and data analysis techniques, most of which were studied in an astrophotography course by Brian Falls. I also want to thank Adam Block for his new NB Colour Mapper Script for PixInsight that helped me a lot in highlighting nebulae in M33.

The observation report documents the whole astrophotography project conducted from August to November 2023. In particular, I was explore and trying to identify potential Wolf-Rayet (WR) nebulae within the Triangulum Galaxy (M33). Utilizing a SvBony SV550 122mm APO refractor telescope and ZWO ASI 2600MC Pro camera, over 211 hours of total exposure time were collected in both broadband and narrowband filters. I pay attention to ten nebular objects, designated GK-1 through GK-10, which exhibited characteristics potentially indicative of WR influence.

The research involved cross-referencing the observed structures with existing astronomical catalogs and databases to ascertain their novelty. No corresponding entries were found, suggesting these objects may be previously uncharted although I also believe that I haven't looked good enough, so this is why I share everything I have at the moment with the community. I am seeking help from the astronomy community to either assist me in identifying these objects or guide me on what I can do about it. Thank you so much to everyone who spends some time here taking a look at my first attempt at producing an image with so much exposure time!
