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.
