Bubble Nebula : NGC 7635 & Messier 52 in RGB-SHO (Daniel.P)

Bubble Nebula : NGC 7635 & Messier 52 in RGB-SHO

I performed all guiding now using my modified version of PHD2 to do Multi Star Guiding.

The guiding is good : I have obtained 1.8 to 1.9 arcsec on the central part of the final image (before deconvolution & measured in PI as Moffat 4).

But now I really have to adjust the position of the field flattener as the corner of the image show some coma.

I have to improve the color of the Open Cluster stars ...

The processing was done in PI as follow :

For each R ,G ,V, Ha, OIII & SII 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 RGBSHO image using NBLRGB combination tool

- Color balance on stars using a star mask

- Color balance on nebula with mask

- Crop image

- Remove residual background non uniformity using DBE

- Slight deconvolution with background and bright star protection

- Perform SCNR (neutral 70%)

- Nonlinear Image Creation

- Color boost using mask to protect background with boost in blue

Final image adjustments performed in Iphoto on Imac (levels adjustments and deflip)

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.
