As new condition ultra narrowband 1.25" Baader filter. 3.5nm bandpass for nice small stars.
Bought and loved it, but planning on going from mono back to OSC so won't have a use for this narrow a bandpass.
Selling my full narrowband set up for multiple reasons: I could do with the money and mono just isn't really doing it for me.

Hello, this is my first attempt on NGC 7635 with my skywatcher 250pds on an NEQ6 synscan mount. These are 7min subs stacked to a total exposure of 5 hours taken with my unmodified canon 700d and a skytech cls filter. No coma corrector was used as I haven't gotten one yet. I'm just wondering how I could make my images look clearer when zoomed in and improve them overall as I can see the image gets more blurry when I zoom in onto the bubble, should I use a higher magnification? Do I need to take more darks to get rid of the redness around the image ? Or perhaps I stretched the image too much in Photoshop? I used 10 darks, 60 bias and 60 flat frames.
Update: I have now further processed my image with greater care and got a much better result.
THIS ITEM HAS NOW BEEN SOLD.
This listing is for my personal narrowband filters (Kayron from Light Vortex Astronomy). They are the Astrodon Hydrogen-Alpha (HA), Oxygen-III (OIII) and Sulphur-II (SII) 3nm 1.25" narrowband set. These are considered the highest-end narrowband filters money can buy, able to produce images of exceptional quality and incredible sharpness, cutting through a vast amount of light pollution. The 3nm variants featured here are fantastic for pulling out fine nebulous structures clearly above background. For more information, please see Astrodon's website:
Please note that these three filters together currently retail at just over £1,710 from UK suppliers, €2,180 from European suppliers or $1,690 from US suppliers. Payment is preferred via bank transfer but PayPal is OK with an extra 2.9% to cover PayPal fees. I'll cover postage to you via tracked Courier.
I welcome any questions you may have regarding this listing. Thank you for looking.
