M51 HaRGB

Revision title: Contrast adjustment

I've wanted to get a nice image of M51 for some time now and this is my attempt at it. I collected over 28hrs of data but in the end I only used a bit under 21hrs because of several issues I encountered along the way. I used my L-Pro to collect the RGB data and my Antlia 5nm to get the NB data and extracted the Ha channel and added it back to the RGB data. I wasn't real happy with it so in the end I integrated all the data together and then used the extracted Ha channel in PM to help to make the Ha regions more prominent. This is pretty close to the full frame of my camera. I'm going to work on a Portrait model to see what I can do to get more detail out of it.

Hope you like, thanks for looking!

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.
