Messier 30

[Atmos]

Shot this a week or two ago as I wanted to compare it against a shot I did a year ago with the Mewlon 250 on a night of below average seeing. This definitely came out sharper!

Just shot RGB for this one over a few hours and due to some miscalculation my second set of R exposures didn't start until 6am; far too late! So some of my star shapes in R aren't the same as G/B which has lead to some flaring on the stars.

Overall it's a bit of a so-so image but this is a fairly over looked globular cluster for imaging :)

I like it Colin, stars are nicely resolved and colour is very good too :thumbsup:

Quite good Colin. A tad soft but as you say low in the horizon you are lucky to get anything useful.

You can also try 2x2 on the 183mm as that gives you 4.8micron pixel equivalents which is handy if the seeing is a little off. It tends to give rounder stars and is a bit more sensitive.

2.4 microns demands good seeing.

Nice one Colin. Globs don't get much love but they can make for great targets. I still haven't quite got the hang of imaging them yet, though I suspect they'd do better with more data that we usually put into them.

nice one col, great star colour in there too.

cheers

Great star color and resolution Colin. That's a tiny one. :thumbsup::thumbsup::thumbsup:

Thanks Suavi :)



Most of it was taken quite high in the sky but definitely still at the mercy of seeing. Problem is that 2x2 binning would very much under sample when at the moment FWHM is around 3-4 pixels.



They really don't get a lot of love but I'd say that seeing plays a bit role into the end product quality. Poorer seeing gives better colour but definitely doesn't show the fainter stars which is the first thing I noticed when comparing last years effort to this one.



Thanks Russ :)



It's certainly not a big one but it's not too small either ;)

Subtly processed - not overpushed. We can still see the unique signature of this particular globular. Beautiful star colours.


Inspired and encouraged by your image, I went back and published a less pushed version of our Pavo globular.

Very good Colin,I agree with all previous comments.

Nice colour and resolution Colin. Couple of faint fuzzies in there too.
