NGC7380_Hubble_2017-8-19

Here it is my Bi-colour Hubble version of NGC 7635 Bubble Nebula, Oiii and Ha only!

Well this probably the last image I process before the "2017 Astro Festival weekend" at Herstmonceux this coming Friday (1st Sep). This will be the first time working there on the "Telescope House" Exhibit.

 

Note:

I add the Ha stars back in near the end of the process, given me smaller stars and no colour Halo's....

 

Information:

Located 7200 ly away, the wizard nebula surrounds the developing open cluster NGC 7380.
