Have had pretty bright skies over the last month, but finally got some that was dark enough to find some detail in NGC300. I was initially concerned by the noisiness of the image, but part of the problem seems to be that the galaxy is close enough to resolve some finer detail and this looks grainy - at least that is my excuse....
Could have done with a bit of Ha to bring out the star formation regions, but I have already spent enough (often fruitless) time pursuing this galaxy - next time maybe.
Thanks for looking. Regards Ray
GSO 200mm F4 with RCC1

cropped and downsized x0.8 to fit
Wow look at all those details yep at 20' across it's a big close face on galaxy so you can sure resolve some stars in there Excellent balance but a minor point does it look a tad bichrome? (Yellow and cyan/blue) ...maybe, so I agree some Ha may well have added something. Never the less a magnificent version of this galaxy...probably the best posted on here this season too

Sprung.. The attached image is how it came out of the processing with no messing with the colour - I tried to be smart and push the blue a bit to enhance the bright regions and compensate for galactic extinction. Thanks for the feedback Mike
No I prefer the first version...you should consider getting back out for just some Ha, can do it from the city too, say 2hr of Ha then blend it into the Red and recombine...that's what I would do anyway ..thne again, perhaps there is little Ha in NGC 300

yep, you are right - I will get some Ha and do it properly, like I should have done in the first place. There are definitely some Ha regions in there.
A mighty nice looking result Ray, Tight stars and detail, wow. I prefere your 1st Rendition also I know nothing about narrowbands etc, but looking forward to the Ha added if you get to, extra cool !

Arrrgghhh tread carefully there! I would not blend Ha into the red channel as you lose control. Ha will dominate and you'll get one of those silly M33 with pink splotches everywhere! Lightly does it and Ha as a separate layer in lighten mode so you retain control.
You've got a masterpiece galaxy image here so don't spoil it!

Hi Bob - thanks

Hi Greg - thanks for the comment. At 8 inch aperure, the atmosphere dominates and optics become less important. The biggest issue with the GSO was getting the mechanical system sorted - everything bends slightly.

thanks Greg - yes, there is always the risk of stuffing it up - will be careful

Thanks Rick. about 3.5 hours lum, about 5 hours RGB total all at 1.17 arc sec (1x1), 200 sec. will go back and check exactly how much in each colour, but red was the problem child due to sodium light pollution and it required a lot of time.

thanks Paul. aperture sure helps, but the biggest problem was getting enough good seeing in combination with dark skies. I am going to have to find a better dark site than this one if I am going to image this sort of stuff.

Thanks Lee. I like the negative version as well - somehow we seem to be able to see detail better when it is reversed - don't know why
