New Antlia 3nm Pro Narrowband Filters v's A Full Moon : The winner - A Rosette

Thanks for the positive feedback, all the detail cam from the Ha - I've posted the integration below - to get this much in 3hrs is a game changer. I know its only one image so far with these new 3nm filters - however it has been a WOW moment for me to get that much information in an image from a relatively short integration time

How do you find the Oiii filter? I find that the uncalibrated images have a few weird gradients compared to the Ha and Sii. Of course this calibrates out with the flats so it's not an issue.

Love it. How much was the set of Antila's Bryan? Are they all 3nM?

Yes they are all 3nm versions of the Antlia narrowband filters Ha, Oiii, Sii and are the 1.25" mounted versions, they were £278 each so pretty much 50% the price of the two premium brands available for 3nm filters -oh the Oiii was more it was £310. And as I said the pay in four option spreads the pain over 4 months

 

Just realised I have been spelling the brand name incorrectly in this thread its Antlia

Here's an uncalibrated 300s Oiii sub - its got some amp-glow on RHS - which I saw in the 300s darks, but not seeing anything strange -just a screengrab from a PI screentransferfunction

Love the colouring on that, I can seem to get that darkish brown to the Ha, all I can get is red, yellow or orange.

Thanks Carole - Its a bit of a Pixinsight mix - so I use a pixel math combination that I found on Coldest Nights website and that gives a red/Green output - I then create another colour mix using the SHO-AIP script which I use pretty much 100% per channel, I then created a Pixelmath equation to mix 70% of the coldestnights mix with 30% of the SHO.

After that I then go into Photoshop and use selective colour to modify the mostly Red and Yellow and that gives me that brown colour ..... its a bit convoluted but does result in a pleasing narrowband colour pallette
