UKS 1 - the faintest globular in MilkyWay

SPX350 F4.53, ATK-16HR, Astrodon filters.

IR IRGB
IR=14x5m
GB=5x5m

This I found in Obscure Globulars website as a challenge and then found Rolf imaged this last year successfully with the SC1 which is amazing for an invisible object! Moon was 50% phase and got nothing in red filter at all so next time tried the IR742nm filter which showed the globular strongly and green/blue showing nothing of the cluster only stars.

This Glob is near M8 Lagoon Neb and took a while to match star patterns with the tiny image on the website. I think this is a strictly IR image owing to the quantity of dust obscuring it. Best results would be by using Astrodon IR filter set for dusty obscured objects.

Regards, John.

Wow! Very cool. Next to M8?... That's probably why I never paid attention. I rarely image that part of the sky.

Well resolved, if that's the faintest you should have no problems nailing any of them. Interesting

Very interesting. Well done.
I only own a photometry I filter. I wonder if it would show up with it. No chance to test it at present due to the unrelenting cloud.

Thanks everyone, just something quick and a bit different.

Louie this has an integrated magnitude of 17.3 but is not on any maps as such and is at RA 17 54 27 Dec -24 08 37 - 5 degrees from galactic equator near M8.

Excellent work, I admire people who chase little hard exotics like this. Similar to the work BOSS super nova teams does. Plenty of pretty pictures going around but these sort of challenges are cool as well.

Good work.

Great going John.
Very interesting these hard to get dust obscured objects. Almost like a treasure hunt!
Opens up a whole new field from the standard BB & NB images we see.

Been some interesting results as well from the big boys using IR filters on many well imaged, well known objects.

I guess areas towards our galactic core, many galaxies & nebula would really benefit and yield some very interesting results.


Thanks for sharing.

Rich

Wow John that's fabulous! I can't believe how much brighter it is in IR, really amazing. It was nearly invisible in my data. IR imaging certainly seem promising with these types of targets.

It's a beautiful image, really well processed and I'm impressed with how resolved it is. The reddish colour also nicely show how obscured it is. A top image, thanks for sharing this
