M22 Globular Cluster in Sagittarius

[Startrek (Martin)]

Imaged M22 last night in Sydney with my 6” f6 newt on the HEQ5
Haven’t imaged this object since September last year so I compared the both images and this time was a significant improvement with no coma
45 x 2 minute dithered guided subs
20 x darks
Canon 600D with Baader coma corrector
ISO800
PHD2 ( 1.4 to 1.6 arc sec error ) low to medium dithering knocks my HEQ5 around a bit and takes a lot longer to recover compared to my EQ6-R mount
BYEOS
Stacked in DSS

Thanks for looking , comments welcome

Very nice Martin. By way of comparison I came across this image of it that I
took some years ago; at least I think it is M22, I've lost the data for the
image. Its a small file, best viewed at about 80%.

Thanks Raymo
I looked at your glob and it has a large star ( with diffraction spike ) located just outside the main core of the glob at approx 7 o’clock
I checked my image and there are no prominent stars that stand out against the main core , mine are roughly similar sizes
In my spare time , I might go through the Messier catalogue and try and identify yours
Thanks for commenting

I found your image you posted , it’s NGC 4833 Southern Butterfly Cluster
I captured this glob back in April this year
That large star makes it unique as not too many globs have it
I just ran a quick check through my glob files and found it ( thankfully I started a good filing system on my laptop for future referencing )
Cheers

Cheers Martin, I couldn't find it among the Messiers, so realised it had to
be just an NGC glob.

Stars look great Martin. Another winner to add to your collection.
