Thanks so much Peter
Appreciate it
Apparently the sweet spot for this camera is between -5C to -10C even though the ZWO specs say the lowest dark current is at -20C
After using a DSLR for over 3 years I’m not use to having images with so little noise from my Bortle 8 location in Sydney
However after I finished M17 around midnight on Wednesday night , I decided to image a Galaxy with the Duoband filter ( not a good idea ) Chose NGC 253 Sculptor galaxy to see what affect the filter has on galaxies
Captured about an hour of data
Processed in RGB , Galaxy resolved with my 6” f6 newt and the new 2600MC well but colour had a greenish cast which looked horrible, couldn’t process the colours right to correct it
So no more narrowband mono or colour on Galaxies , I’ll just stick to Nebula and Planetary Nebula under heavy light polluted skies
Gotta get back down the coast , but bit busy at the moment with grandkids etc.. and sorting out my Dads deceased estate etc ..
Cheers
