M 27 - Dumbbell Nebula - RGB-HOO

This is the first image that I processed from this summer holidays.

The APO is now correctly collimated

I am using my new Ioptron CEM120EC2 mount that I just acquired to replace my AZEQ6. The performance of this mount is EXCELLENT. The mount has no Periodic Error and has very good pointing accuracy due to its optical encoders on both RA and DEC axis.

Starting this summer, I have used a modified version of PHD2 to do Multi Star Guiding. My goal was to avoid "chasing the seeing" by guiding on the average position of a set of stars (5 to 10 typically) as opposed to a single star. This program is working without any issue and I use it on a routine basis now.

The processing was done in PI as follow :

For each R ,G ,V, Ha & OIII channels :

- Flat Field Dark Substraction

- Flat Field Integration

- Images Calibration (Dark Substraction and FF correction)

- Cosmetic Correction

- Image Registration

- Image Integration

- Noise Reduction (Demure)

Using each integrated channel :

- Created RGB color image using channel combination

- Created RGBHOO image using NBLRGB combination tool

- Nonlinear Image Creation

- Crop and deflip image

- Color Balance on stars

- HDR transform

- Color boost using mask to protect background

Final image adjustments performed in Iphoto on Imac (levels adjustments, and further color boost)

I plan to improve :

- the color of the M27 core area

- the display of the stars

B version : Ha & OIII frames only, color balance on stars. The core area color is better.

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.
