peter shah Posted February 12, 2021 Share Posted February 12, 2021 A little low in contrast but I can see how deep it is....Detail is great....I quite like the look of these Antlia filters Quote Link to comment Share on other sites More sharing options...

Wyvern Posted February 12, 2021 Share Posted February 12, 2021 Really nice! I have the 3.5nm versions and am thrilled with their performance and it looks like these great too. 1 Quote Link to comment Share on other sites More sharing options...

Just about John, only took a few months, still a couple of niggly things regarding the primary mirror screws to sort out. Dave Quote Link to comment Share on other sites More sharing options...

Filters seem to compare well with my Astrodon 3nm, only got Ha ATM but O3 is on the way Dave 1 Quote Link to comment Share on other sites More sharing options...

The primary locking screws can't be locked very much as they push the alignment out but if left slightly loose they work themselves undone, I've put some springs that I had around under them to keep them under tension but need to get some better fitting ones, they're also grinding into the aluminium of the mirror cell and could do with replacing with plastic ended ones, the primary adjusting screws screw though a casting with a spring on them but those springs are too big and fall off the side of the casting so need to fit some washers on them but it's useable.

Wyvern Posted February 13, 2021 Share Posted February 13, 2021 Might be worth looking at increasing the exposure time, looks like there's plenty more depth to be used up there. Quote Link to comment Share on other sites More sharing options...
