I have added 2 nights of exposures (the 13th and 15th of April) to my 30 hours exposure image of ngc 7023 taken during 2010, 2011 and 2014. Mostly are 180 secs subs unguided. Telescope is a Vixen ED114 + Hotech Field flattener, camera is a modded 600D at 800 iso and mount is a Vixen GPDX + skysensor 2000 PC. Stacked with DSS and processed with PS. Image is still very noisy and it's very hard to enahance the dark nebulaes structures that are in this part of the sky. I should move to a decent sky to image such a weak targets, but unfortuntelly I have no chance to do so. Therefore my only option is to add hours of exposures every year and see the improvement. Thanks for looking.

Added link to the fits file so if someone wants to process it he can do.

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.
