NGC 6604 - GUM 85 and Dobashi 0782 on a misty night...poor quality data (Claudio Tenreiro)

NGC 6604 - GUM 85 and Dobashi 0782 on a misty night...poor quality data

A while ago, in a wide field image of the region taken with my SpaceCat 51, GUM85 did appear as a tiny small red dot, you can see it here, on the lower right hand side of the diagonal:

so I did try a new capture, using the ED80, including NGC 6604, however the seeing was quite bad, mostly misty buy I decided to do a try on the data.
Stars are not nice and, I had to push the red, in order to counter balance the yellowish colour of the stars, those on the lower left quarter of the image, they are quite intense yellow/brown.
I am not so happy, but it shows that, using an OSC, that almost the whole area is dominated by intense red, you can also compare with this image:

or even with this one using Ha filter (ideal for Ha):

So, maybe, next time, with a different scope, and hopefully better seeing, I can come back to enhance the object by itself (GUM85), that is quite interesting for imaging it.

It was quite an exercise to stretch this poor data set anyway.

Description: New colour calibration, so better balance of the red, however still there is an artificial enhancement of the yellow of the stars, so more analysis to be done.

Description: After analysing different colour balances, considering the poor quality of the data, I believe that this is the closest to the real thing, even I did compared it with some professional images of the region.
Also it can be compared with images having Ha filters, and they come out completely red.

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.
