Popular Post Astrobdlbug Posted March 2, 2021 Popular Post Share Posted March 2, 2021 (edited) So I made a rash buying choice last week after seeing results of @Wyvern image of Rosette using the Antlia 3.5nm filters I contacted Zoltan and he had just taken delivery of the new Antlia 3nm Pro versions - so I made a unilateral decision and opted for the pay in four paypal route and next day a lovely set of 3nm filters arrived at my doorstep. TBH I had been looking at 3nm option,at least for Ha, for a while but the price hike on Astrodon and Chroma recently just felt that ownership of these coveted items was slipping over the horizon. So it was a punt in the dark so to speak - but oh boy - either I am easliy impressed (true) or these filters deliver in buckets. I posted a couple of screenshots of the Ha subs over the weekend in the Anyone imaging tonight thread - honestly with 98-100% moon the 300s subs looked like a final integration..... So yes another end of season Rosette - I can say its been rather good fun processing the data , yes with moon there was gradients - to be expected- but rlatively easy to fix with DBE. Would have been great to image another target without the moon later this week, but weather forecast looks grim for imaging. The other 'win' was that this was the first time in well over a year that I had set up mu AT106EDT with the FF/FR attached and my old notes with spacing was spot on and also setting up the OAG with Lodestar all worked out an I got guiding down to 0.84RMS best and worst around 1.3RMS - I'm imaging at just under 1.5arcSec/Pixel with this setup Image details Antila 3nm Pro filters Ha - 36 x 300s Oiii - 36 x 300s Sii - 36 x 300s Total 9hrs Integrated with APP and processed PI and PS So I am awarding the winning Rosette to the Antlia 3nm Pro filters Bryan Edited March 4, 2021 by Astrobdlbug 14 Quote Link to comment Share on other sites More sharing options...

Astrobdlbug Posted March 3, 2021 Author Share Posted March 3, 2021 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 2 Quote Link to comment Share on other sites More sharing options...
Wyvern Posted March 4, 2021 Share Posted March 4, 2021 That is superb! I think I need some of the 3nm ones now 😂. Wish I could get some more time on this target... Glad they are working out for you! That image certainly shows what they can do. 1 Quote Link to comment Share on other sites More sharing options...

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.

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 1 Quote Link to comment Share on other sites More sharing options...

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 Bryan Edited March 4, 2021 by Astrobdlbug Quote Link to comment Share on other sites More sharing options...
Carastro Posted March 4, 2021 Share Posted March 4, 2021 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. Carole Quote Link to comment Share on other sites More sharing options...

Carole 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 Bryan Quote Link to comment Share on other sites More sharing options...
