Comparison of Antlia Triband vs ZWO dual band

[AstroMuni]

Hi all,

I had a chance to do a quick comparison between these two filters and thought I would share it here.

Both sets of images (30 x 60s) taken on the same night with setup of SW130pds + ASI533MC Pro with gain 240, offset 70 and -5deg. Stacked + Background extraction done in Siril followed by Autostretch.

With ZWO dual band https://www.firstlightoptics.com/narrowband/zwo-2-duo-band-dual-narrowband-filter.html

Are you sure you have those the right way around as I would have expected the teal colour from the tri-band and the green from the duel band. 

That tri-band filter is not what I would select for an emission nebula. For the 533 i would grab a 1.25.

Actually while that ZWO is technically a duel band filter its very wide in the OIII and so is not a true duel narrow band filter. I would get something like the L-Extreme instead. It looks to be almost 40nm wide.

The top photo looks like very similar to one I took last year using a ZWO L-Enhance filter - although in this case my subs were 180 seconds, and I took 60 of them, with a fairly slow Tak TSA 102 f/8 refractor.

I did check and I have it the right way around. It wasnt meant to be a which filter is better OR the most suited for a particular target type of comparison. Its just what I had in my possession at the time comparison 🙂

Indeed, they look quite similar. I wish I had all the filters to do a comprehensive comparison 😉

Thankfully S@N mag did one recently https://www.skyatnightmagazine.com/advice/multi-band-filters-astrophotography/

I've been on the fence to which dual filter to but for ages, I grabbed the cheaper Askar duo on my last ride up to FLO. Only had a couple of hours on it last night and my backfocus needs work but I'm kinda happy so far. Need to see what a bright star does if there are any halos. When my neighbours house gets out of the way i'll take a similar shot of the veil and post it here. 

Anyone got any links or pointers for processing dual band images? 

Here's a rushed stretch and blurX/NoiseX of the heart from last night.
