Very nice image Kris. The filter has done a superb job on Halos. Can I ask what durations your individual subs were ?

Cheers Paul


Thank you Paul. 😀 I am really pleased with that, too. Did not really know what to expect, first time using it. These were 300s exposures, looking at the ADU readings I think there was still some room for longer exposures at the same gain 100. I thought I would just stick to 300s to see what comes out of it.
