had some quite nice seeing for this - only lasted for a few hours, but enough to get some good data . I was particularly pleased to see the background galaxies all over the place (even through the main galaxy) and the framing is off centre to get a good collection. It is not particularly deep, but the resolution was good.
Still I was using fast download from my QHY9 mono camera
( but the same sized scope. )
That adds noise equivalent to sky noise that I didn't know about before.
I'll have to try this target again if I ever get the time.
Lovely Ray. Where did you take this from, a dark site?
thanks Simon. In Ardrossan, a small seaside country town. It is not particularly dark, but OK. seeing can be good during the transition seasons, but is messed up in Winter by the nearby sea, which is much warmer than the night air.

thanks very much Colin - it was tantalising to see so many almost resolved dots as well - maybe time to start looking at a bigger scope .

Hi Geoff. seeing was good for much of it and the stacked FWHM was just under 2 arcsec.

( but the same sized scope. )

Well done with the 10" f4.
cheers

thanks very much Allan. our images are very similar in colour and seem to differ mainly in scale. imaging through LP sure can make life hard.
A very enjoyable view of NGC 300 that Ray It's one of those galaxies that sits a great field of background galaxies too which always makes for an awesome scene.
Great image Ray. Are you continuing to acquire data for this target? Given the nodular details your getting, I can't help but wonder what a bit of Ha would add to the mix.
That is such a nice sharp image with great colour! Just how much improvement in resolution do you think you are getting through this "lucky imaging?" I think with your previous Trius you were doing 300 sec, so now 5x shorter for luminance and guiding also less of a factor. I'm curious how you stacked so many luminance frames? One go, or several smaller stacks?

Hi Ray,
Your image is just extraordinary.
It's so sharp & the colours are perfect.
You have resolved so many individual stars inside the galaxy.
Going under 2 arc seconds & plenty of integration time
with dark skies & obviously a perfectly collimated & guided scope
has given professional looking results that would compare with
a much larger scope.
That's a great result, Ray! Love the main galaxy and also the smaller fuzzies. The one at 3 o'clock is especially cool.
Cheers,
Rick.
thanks Rick. yep that one looks neat - pity it is so far away

thank you Glen. No, cloudy here, so that is probably that for this year. I liked Mike's version with the Ha, so it can add to the galaxy. Thanks for the suggestion

Its amazing you can make out knots of the brighter stars at such an unimaginable distance.
Greg.
thanks Greg, yeh, its great that we can resolve stars at such a distance (I suppose that is what they are)

The stacked FWHM of under 2 sec arc goes some way to explaining the instantaneous reaction. Faultless gear and magnificent sky.
Trish and I will have fun coming back to your photo several times.
Best,
Mike
thanks M&T. the sky did it's bit this time - way better than average. Would have been a strange sight for a casual visitor - an old guy wandering around in the dark, looking at the sky and muttering "you bewdy".

This makes me want to sell my Trius!

Hi Peter. I think that the "mildly fortuitous" imaging drops the FWHM by a bit in average seeing. In really good seeing it still worthwhile, but less effective. By far the biggest advantage is with narrowband, where my system is typically sky noise limited at about 10 minutes - vs a couple of hours with the 694.

Very well done!
I hope the data I've been collecting on this comes out half as well as this.

thanks Tim - looking forward to your image
