Antlia Triband RGB Ultra Filters

[floyd_2]

Just wondering if anyone is yet to have any experience with the Antlia Triband RGB Ultra Filter. I love using my OSC for EAA astronomy but find that most filters tend to give way too much false colour to my subs. The Antlia Triband looks like (on paper) that it might be something worth trying to combat light pollution AND keep more natural colour in my shots.

I have one on the way, so Ill test it out soon...:D

Hi Floyd,
I know what you mean about natural colour. I seem to get more natural colour from my OSC than Mono. Recently I have been shooting with the OSC and using the narrowband SHO filters with Mono camera and using these stacked subs as luminance layers. This helps enhance the colours taken with OSC. Appears to work quite well.

I couldn't resist and grabbed one at about 1am this morning lol. I will eagerly await its arrival and clear skies!

From my very short testing of a pre-production version, it appears to work well from my Bortle 7 sky. Very good halo suppression as compared to something like the L-Pro filter. Colour balance appears better than L-pro with improved blue transmission.

It’s sounding positive Ted. Thanks for the feedback. I hope that we can score some clear nights soon so that I can get some sky time!

Under Bortle 7/8 skies in Sydney my ZWO 2600MC ( with its UV/IR cut internal protective window ) provides great RGB colour on broadband targets (eg: Trifid Nebula and most Galaxies ) during new Moon periods. It’s just all the LP gradient you have to deal with but Startools does a great job in that area.I don’t both with Broadband targets when the moon is up and growing ,I break out the Antlia ALPT.
I think any filter you use to suppress LP and/or moon glare is going to have some negative affect on true RGB broadband spectrum
This new Antlia RGB may have found the holy grail of OSC Broadband filters ?
The relatively new Antlia ALPT Dualband OSC filter is a real winner compared to others Ive used like ZWO , L Enhance , L Extreme, I love it . I’ve yet to see a thorough report on the 3nm L Ultimate ?

Cheers

I’ll be testing it tonight on NGC 2020

Following with much interest…

Thanks
Hopefully you capture plenty of data late in the evening / early hours when the moon is descending
Looking forward to seeing your results

Looking forward to seeing how your filter behaves Nik. Nothing but cloud here yet again this evening :(

Autofocusing with the L-ultimate filter has been an adventure you need 15 second exposures so that's taking a while
see how my subs turn out

Wondering if anyone’s got any experience with this filter yet? I’m seriously considering purchasing one for osc galaxy imaging in my b7 location… in particular whether it does anything at all to reduce gradients?

[Startrek]

I just read the specs on the Testar site and the filter is basically a mono luminance filter ( UV/ IR Cut ) with specific RGB band passes
I don’t know how cameras like my ZWO 2600MC will behave as it already has a Luminance type UV/IR Cut protective window over the sensor.
Yes it will block some LP but the RGB signal may be very weak ???
It may be more suited to the 533MC, 294MC and 183MC cameras which just have an AR protective window for dust and humidity.

There’s one positive review from a guy near Hobart using an f2 RASA

I might check on CN
