NGC 300 on a warm night

Final Image NGC 300 captured at my weekender ending a great week imaging galaxies with clear skies and good seeing
Unfortunately this night was quite warm at around 21 degrees and the DSLR even with cooling fan was reading 26 to 27 degrees ( not ideal for 5 minute subs ) Anyway managed to massage ,remove and hide quite amount of noise during processing in Startools, I donít know what I would without this great software
8Ē f5 Bintel GSO newt in an EQ6-R Mount
24 x 5 minute dithered guided subs
20 x darks
Canon 600D with Baader coma corrector
ISO 800
Goto and tracking with EQMOD, Stellarium Scope and Stellarium
Capture software BYEOS
PHD2 guiding at 0.70 to 0.80 arc sec error ( guiding was running extremely well , this low to mid end mount is a winner considering my payload )
Stacked in DSS
Processed in Startools ( noise exterminator)
Final image still has a bit background noise but considering using a DSLR on a warmish night with long subs Iím fairly happy with the outcome

Thanks for looking , comments always welcome

That's a decent image of NGC300 Martin, there must be something in the Startools bag of tricks to help with the horizontal banding, do you know what caused it?
Cheers,
Tony

Thanks Tony
Yes the image had bad horizontal banding after stretching which is usually caused by the Camera , DSLRs are notorious for banding in long subs plus I didnít take proper darks , I used a master dark from a different previous capture , therefore different temperatures
Startools has 2 algorithms to minimise it , which worked to some degree
Thanks again

A beautiful rendition Martin. Well done. Nice and soft. Pitty about the banding but otherwise really nice

Try !!!! Try is building in defeat...do or die...I will be in Sydney by Monday and if there are no clouds you know what all here are expecting...And heck even if there are clouds there is bound to be a gap..how long does a Moon run take.

And what about some solar work? Actually I have a myal cover for a six inch if you want..no cost just pick it up...or I guess I could post it...

Thanks for the kind offer but the Sun is my enemy now ( only joking ) I had too much of it as a young bloke surfing and now Iím paying for it , 2 melanomas and 3 basil carcinomas plus endless keratosis
A trip to the skin cancer guy every 6 months for me and it will get worse as the years roll on
Iím a night guy now , covered up during the day but a little too late as damage was done 40 years ago
