The way my backyard is structured makes it extremely hard to image anything outside of the celestial north pole and DSO's passing high overhead to the south. Objects such as the Needle Galaxy are only available for about one hour a night due to trees.

The seeing and transparency were not great, so I could not take advantage of the full resolution of my RC. However, a clear night is a clear night and you gotta take what you can get.

I think I might bump up my exposure time a bit for the next object. Sixty seconds for broadband is already generous in bortle 8, but I probably spend 40 minutes imaging and 20 minutes dithering per hour. I might try 120 seconds as my go to sub length for broadband city imaging. Speaking of dithering, its nice to have a mount that can do it reliably now. It really makes a difference, especially for these OSC's!

HOWEVER I decided to give APP a go for stacking and oh boy, does it blow DSS out of the water!

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.
