Duo narrow band help

[Calzune]

Hi

Im planning on buying a duo narrow and filter for my modded dslr and for an upcoming cooled camera (osc) 

Im wondering if anyone have any good tips on what brand etc to use. 

I have seen ZWO and stc sells duo narrow bands.

I don't want to spend a fortune on this filter so this is the cheapest I have found. 

What I need is a 2" filter  that I thread on my field flattner right? 

Im new to this hobby so I need all help I can get

i think the https://www.firstlightoptics.com/light-pollution-reduction-imaging/optolong-l-enhance-dual-narrowband-deep-sky-imaging-filter.html reviews favourably

There is also the Tri-band (or Quad Band depending on your Sky quality) filter from Altair Astro which I use and has had some good results..

It's about 50 dollars more than what I planned... But I guess I have to stretch the budget if I have to. 

The price is almost the same between those 2 filters, so which one is the better one? Or are they the same? Just different manufacturers?

I saw a video that that filter produces halos around the stars, have you noticed that?

Not as yet, but I also saw it on the video!

I choosed the Optolong L-eNhance Dual Narrowband filter. 170$ on aliexpress 😄
