Messier 106 and NGC4217 : Two galaxies in Canes Venatici

My objective was to see M106 with surrounding galaxies and the Ha features in M106, especially the features coming from the core of the galaxy.

I also realize with this photo that my APO needed some collimation adjustments (see the green coma on the left side of the image) ... which has been done mid May !

Note : version B is using 2017 OSC data with the new colors from 2020

Processing in PI

- Dark & Flat calibration of L, R, G, B & Ha channels

- Cosmetic Correction

- Registration

- Integration

- Mure Denoise each channel

- Add Ha to R channel using PixelMath

- Build RGB

- DBE L & RGB images

- MultiScaleMedianTransform denoise

- Delinearisation of L and RGB images using HT

- Extract a & b color channels from RGB image

- Combine L, a & b channels

- Color saturation (and desaturate bkg)

- TGV denoise

In Mac Photo : crop, deflip, levels, sharpness

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.
