Hi guys

Looking at getting some rgb filters and I def understand you get what you pay for.

Anyone able to recommend a quality 1.25 set for a reasonable price .

It's often work keeping an eye out in the classifieds or on AB&S for filter sets for imaging.

What camera are you using? The reason I ask is that ZWO have a set of rgb filters that are matched to the performance of the 1600 chip, so if you have one of those, they might be worth the extra investment.

Yesterday I took delivery of Altair Astro LRGB premium filters.  Not tried them yet but thought the price was reasonable.

Altair Astro Premium 1.25" LRGB CCD Filter Set UV/IR Block & AR Coating.

Anyone tried these ?

Think the altair lrgb are a clone of an optolong lrgb which are a clone of something else as they all have the same schott 2mm glass just different holders, optolong are just more expensive, so will probably get the AA RGB to match my AA narrowband types, would like to get a recommendation on these. ton

People get along fine with the zwo premium asi1600 set. It's decent and will work with more than just the 1600. The next step up from that is really the baader or astronomic set. Not so sure about the optolong set or AA set. Best idea is to look at shots of the horse's head nebula shot with different filters on astrobin. Look for reflections on the brightest star. 

Have you manage to take a test image yet?

The astronomic ones are as close to par focal as you will get, not used baader RGB so can't comment on those, but have used baader narrowband and they are a nice set.

[ebdons]

Hi, not sure on  specifics but if the glass and holder are the same spec thread depth etc, narrowband and lrgb should be exact or close to parfocal? I have my astronomic 12nm set which are parfocal but with 1mm glass thickness, but not totally sure when the glass is thicker 2mm 2.1mm zwo and 3mm type if  this the case? would need to test to be sure? Ton

Baader LRGB is pretty damn good for the money, pretty equivalent to the Astronomik from what I've seen.

[ollypenrice]

I use the Baaders. I'm pretty sure that any deviation from parfocality comes not from the filters but from the colour correction of the optics.

Sorry to jump in on the thread,  I am also looking at filters (NB first and then RGB). It looks like Astronomik have 2 versions of their RGB filters, the ones you have being one. Do you know what the difference is. I have read up on them and still not really sure ? 

After reading up a bit it seems the Baader are good with the Astronomiks being similar if not a little better.

[Fieldsy]

I’ve gone Baader LRGB and Baader NB .

thanks all
