Seagull Nebula IC2177

In part 2 of (Astro-) March Madness, I present my rendition of the Seagull nebula taken over several nights with my L-Enhance filter. I am still debating on my preferences between the L-Enhance and the L-Extreme because of the halo effects I've been observing with the L-Extreme. Since this image has a couple bright stars enbedded in the nebula, I wanted to be safe and be sure I got some good data. The L-Enhance has made a really good first-impression on me!

The targets in negative declinations around the Orion belt area like this one are tough for me to get a lot of integration time on as I have a bunch of very large trees to the southeast and southwest that limits my time per session, so I had to build data over three nights. Processing-wise, I am really happy with this one - I think it's one of my best efforts so far. I am finally getting comfortable with using PixInsight; it really is powerful for dealing with smoothing the background noise out. I have been trying hard not to over-work or over-darken the background sky - just do enough smoothing to try to make it look at least somewhat natural (or what passes for that in sub-urban environments). Even with the narrowband filter, I still have a lot of light pollution noise in the raw background, which is much worse in this direction in the sky toward the city center. While my image isn't perfect, I'm really excited at how much I feel like my DSO processing is improving. Now back to practicing on some more galaxies!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
