Anyone using Altair 2" Premium Narrowband CCD Filter Set?

[oymd]

Evening everyone

I’m slowly assimilating my future MONO setup  

I’m planning on getting 2” LRGB and NB filters, even though the plan, for now, will be an APC-S sized mono sensor.

For filters, my eye is on Baader’s new CMOS optimised filters, but I’ve read some negative comments with regards to halos on CNs. I’m looking at the NON F2 filters, as my scope is an Esprit 100ED f/5.5.

I realise that short of Chroma and Astrodons, all filters will have issues.

The Baaders are not CHEAP. £580 for the 6.5nm set and £915 for the 3.5nm set.

So, I’m thinking of getting the Altair Astro NB premium set. They are 2”, 6.5nm and £475.

I’ve seen ZERO reviews or feedback on the internet regarding their performance or quality?

I tend to like Altair’s products, and anything I’ve bought or used from Altair has always been QUALITY.

Whats the word on these filters?

Would be immense if someone can give me some feedback on them?

Many thanks

Antlia look like they're better than most but without the price tag of Astrodon and chroma .. worth a thought

Just did a quick search on Antlia. 
 I could only find them on RVO. 
The 2” are all 3nm Pro series. 
The three filters are £1374!!

Thats an entirely different price bracket!

Sorry but I don't know what the altair ones were price wise, other than cheaper..I would expect them to be cheaper than baader, but I'd  also expect them not to be as good..price of a big sensor eh

Yes. But the new Baaders are just £125 more for the set!?

So, obviously not that cheap?

Wish someone who has actually used them pick up on this thread and provide some feedback. 
 

I doubt they would be rubbish compared to Optolong/ZWO and similar cheap NB filter offerings. 
 

I generally have had god experience with Altair products.

I think they're the same as optolong, same bandwidth

I have a set of Altair Astro premium 6.5nm 1.25” filters and I suffered from halos but mainly on Oiii which prompted me to upgrade to astrodon filters (only 1.25” second hand)

Excellent! Finally someone out there who uses/used these filters!

So, overall, are you happy with the filters?

From my research, I think that almost ALL O3 filters suffer most from halos, except for the Astrodons and Chroma. 
 

Were you satisfied with the Halpha and S2 6.5nm filters?

sorry for the delay in my response

it’s my wedding anniversary!
 

I will try and dig out some files to give you some examples. 

I was happy when I first used them and I think the ha and sii were halo free but it was my first narrowband imaging rig post dslr so the difference was amazing to me!

I didn’t use them long before I swapped the Oiii, (I saw an astrodon oiii 5nm for £250) and I continued with the Altair ha and sii and astrodon oiii for a few months before I saw a full set of astrodons including rgb for £900 so I swapped the lot 

I hope that helps?

Sorry, last question. Moving to Astrodon, was it night and day?

I’m afraid so. 
especially Oiii

my first image with the new Oiii filter 

previously I would have had a halo to deal with on this

unfortunately I can’t remember if the Ha and Sii are astrodon or Altair, sorry 

I have since bought a 3nm Oiii to assist capturing that bandwidth under moonlight but not had the opportunity to really test it

However, now I’m dealing with the CCD/CMOS issue and considering a complete shakeup of my imaging rigg!
It never ends!! 🙄
