The Perseus Cluster of Galaxies

Your Shot with Voyager

Hi all,

here is another image with a rather long integration time (to overcome the light pollution). Voyager gathered the data flawlessly night after night:

This is a wonderful result Vitali, deep and with great details.
Congratulations, thank for sharing and for using Voyager.

All the best

Thank you very much Leonardo.

I felt that processing was not good enough for the data. Here is my new attempt:

Thanks to all who liked the first image.

No sure about the color balancing in 2nd image. The galaxy should be yellow like in the first. Background is a little clear in the second. I think is a great result of a really difficult target.

If you can get some info about for your processing this is my attempt, I think can be a good reference:

Again congratulations for your wonderful result

Thanks Leonardo. You have a great image of the cluster. A lot of details in galaxies. I like it a lot.

My first image used PhotometricColorCalibration in PixInsight, i.e. the colors were calibrated using the stars. For the second image I’ve used the two central galaxies as a white reference for the ColorCalibration process. I hoped that the details in the galaxies would be easier to see.

I will definitely try to re-process the data again. I think that the FITS files have more information, than I was able to reveal so far :slight_smile:

Best regards,
Vitali

Beautiful image. Nice shot Vitali! It appears difficult enough that I don’t even want to give it a try lol.

Wow are those red in the center real?

Thank you very much Yizhou.

Here is another version which uses AutoColor script ( http://www.skypixels.at/pixinsight_scripts.html ) for color balancing:

Why shouldn’t they be real? need just dedicated processing and a lot of color data

Great shot Vitali! What bortle areas it was shot from?

Thanks Michael. I would estimate the sky here as Bortle 6. The Milky Way can be sometimes visible right overhead if the air humidity is low and transparency is high.
Best regards,
Vitali
