Hi all,
NGC6441 is one of the most massive and metal-rich globular clusters in our galaxy.It is also one of the most unusual due to its reddened colour. Its placement near the bulge of the Milky Way means that its brightness is diminished by intervening dust and gas.
The reason that this is visually one of my favourite objects is its distinctive colour in a large telescope such as my 14" LX200R, coupled with the bright star, G Scorpii, in the same field of view.

My image here was taken on 11 May 2013 under clear dark skies at Leyburn last weekend with the 150 mmF6 MN61 and ST2000 camera.The scope has resolved most of the stars across its face.I hoped to bring out the colours that make this region so visually stunning. I hope you enjoy it too.

Image comprises 3x2minutes subs for each of RGB.

Love that shot Greg. :thumbsup: Beautiful. That's some serious dovetail you've got on that rig. :)

That's a very nice contrast, Greg.

Very interesting Greg, will try to get a visual on this GC as well.
yeah, that is some serious dovetailing on the poor EQ6.
would you have any pics of how its setup?

Hi guys
thanks for your kind comments.
In response to you request for mount pics, i added another one from September last year to my first post above that shows more detail. Note that these aluminium extrusions are specials ( actually discarded at work) and the whole platform, was very rigid, and quite heavy. It was only intended to be a temporary platform until i built something more permanent, but i deliberately chose the original extrusions in this pic for their rigidity.
Note that, as a testament to the NEQ6 mount, it handled this weight and tracked nicely just the same. Correct balance is sooo important. Since then, i have the same gear attached, but on a lighter aluminium frame made of 25mm square box ally.

Great image, Greg. It's very impressive how well you have the NEQ6 tracking!

Great looking photo Greg.

Nice setup. I'm impressed with what the EQ6 can hold.

Thx guys, yes, the NEQ6 will do well as long as its balanced nicely.
It was probably near its practical limit with that gear fitted.
