The Great Peacock Cluster

Hello,

Another image I processed from a quickie exposure after my observation session on 25th June... I located this globular cluster in the eyepiece in my 14" Dobsonian (among observing other objects) and it looked absolutely fantastic, so after I concluded my observation, I powered the C8 and decided to image this great specimen of an eyepiece vision.
After 12 x 300 second luminance subs, the winds really picked up, forcing me to end imaging with only 1 hour of luma data.
As I stacked what I had, I realised that I imaged this globular a bit over a year ago... completely forgot about it... and still had the raw RGB subs on the HDD from back than... so I aligned that data to tonights luminance resulting in this shared image. 

NGC 6752, also known as the Great Peacock Globular or the Pavo Globular Cluster, is a globular cluster in the constellation Pavo.
It is the fourth-brightest globular cluster in the sky, after Omega Centauri, 47 Tucanae and Messier 22, respectively. It is best seen from June to October in the Southern Hemisphere.

Imaged using a 8" SCT at f6.3 (1280mm focal length), with a QHY268M camera.

The total integration time for this image through all of the LRGB filters was 4 hours and 12 minutes.
Exposures: L:12x300s @ FW:31 used as luminance from last years R:20x120s G:19x180s B:19x300s @ HCG:62/OFS:25 data.

Thank for looking,
Clear skies,
MG
