Which filter to upgrade first?

[Anubis1311]

Looking to upgrade from ZWO 7nm NB filters to Antlia 3nm filters. Haven’t got the funds to buy all 3 at once so will do one at a time. My initial thoughts are to get the Oiii, then Ha and finally Sii.

is this the best order to upgrade them?

Ha first would be my preference then oiii then Sii.  But either way, Sii last.

Oh really? I thought Oiii as that would be the biggest improvement filter to filter. I guess given most targets have more Ha that actually makes sense. I’ll go for the Ha first. Thanks

I had the exact same feeling : my O3 stand to gain the most from good quality, whereas getting better Ha feels like it's easier with relatively little time investment.

But then again it's true that Luminance tends to come from Ha so getting smaller stars and better detail will pay off on the overall image quality.

Did you upgrade then? And if you did, if you were upgrading again which way would you go knowing what you know now about your filters?

I moved to ultranarrowband and did it one at a time with Ha first then Oiii then Sii.
