Well I never thought I would see this double cluster at this wide an angle - when I have imaged it from home it has filled half the field of view! We also just about have the heart and soul nebula in the image too - shame we did not lower the cluster down a little bit to get them both in. I always thought the soul nebula looked more like a little baby! Pier 4 is a ZWO ASI-2066MC Pro OSC, with a Sigma 105mm f/1.4 lens stopped to F/2, an Astromechanics focuser, guided with a ZWO ASI-120 Mini and ZWO Mini guide scope, on an Astro Physics AP900 GTo3 mount. The mount actually runs unguided, so the guide scope is in there only as a backup. I used 120 subs of this, at 30s long each, creating an integration time of 1 hour! Take care...

A lovely image Simon, Always nice seeing a double cluster Yes I agree, it's a shame that we didn't get both in together

Hi Simon,  Hope you are well and great to see you turning out some more images. Now onto that image itself.  Had you not posted what the image was I could quite easily have been fooled into thinking that this was taken from a mini submarine deep underwater showing the bright "eyes" of an approaching dragon fish in the bioluminescence. That is really wide with those 2 nebulae at the top that are very difficult to capture together without mosaicing.  Well done,  Best regards,  Ray
