Abell 61 - mono O3 + rgb from other scope

This image is basically the image below:

https://astrob.in/p2d4bj/B/

with color information coming from almost 9 hours exposures in 3 nights (120 secs each unguided subs) taken with an Acuter 90ED reduced to F 6.7 with a AP reducer, and a modded Canon 600d, with Astronomik CLS CCD filter. The telescope was mounted on top of the Orion Newton 250 f 3.9, with which the O3 image was taken. All on top of an Ioptron CEM60.

Resulting image was almost monochrome,. I had to increase saturation a lot in order to bring out some color. This image was used as color layer on the mono image with PS.

Abell 61 is a very weak and old planetary nebula in the Cygnus constellation.

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.
