NGC1499 RGB OSC in 45 min

Picture done with 25 subs of 1min50 which is about the limit of single exposure time for the moment with ioptrion Skyguider. I had more than 60 subs but unfortunately high humidity in the sky and Moon light prevent me to keep most of them for the final stacking. Nevertheless, it is quite amazing what we can do with an uncooled OSC these days. I find RGB on NHC1499 often quite boring since there is lack of contrast in the nebula which comes out just "red" when doing standard processing. I tried to enhance a bit the contrast by playing with the RGB layers using separate starless masks for each colour layer. The pictures were done with f/2.4.
Hope you can enjoy the result.

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.
