North America and Pelican Nebula

First imaging project with the SharpStar 61EDPHII "Triplet" refractor. I captured this image with the 61EDPH (II) focal reducer / flattener. Sadly the reducer seems to introduce CA and while shooting RGB data for this the blue filter was bad so I had to toss it. A possible promising solution is I ordered a set of Astronomiks Deep Sky filters which the blue filter has the stronger blue cutoff around 425nm. Focus tests with the filter set prior to collecting the OIII data for this look good, so just need some full length subs for the final say. Otherwise this little scope is going to great addition to my collection. There are many wide field images I have wanted to do over the years that now I will.

The original plan was to do this as HaRGB, but with the blue data hosed, I decided try a Bicolor approach and do Ha-OIII. That turned into a fun processing project as there a few different ways to map this. I slowly got it down to RGB and Hubble palette and then just started to like the RGB. I was hoping to get some RGB data for star colors, but alas forest fires in Canada had a haze overhead last night that ruined that idea.

Description: Many thanks the @JamesR for posting a tip on CN to use starnet in PI to help with the star colors while processing in bicolor.

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.
