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.
My first relative success at this target.
Some dust mites show because the mount had good tracking and I used no darks nor flats. With my camera the cure should be quite simply to power cycle off/on so that auto-cleaning moves the dust elsewhere.
Capture: Olympus E-PL6 on Skywatcher 130PDS at 565mm/4.35 with SWCC and didymium filter on Omegon EQ-300 tracking RA

Site: 50km from Paris (France), sky Bortle ~ 4
Processing: Regim 3.4, Fotoxx 12.01+
First view of the Sun for almost a month, but the wait was worth it. The large sunspot has split into 2 umbra, both within the same penumbra. Plage and filament activity nearby. There is a large prominence just above this on the oncoming limb and 3 other prominences on this limb. On the Western limb there is another even larger prominence. I will set up for WL and have a close look at the AR. Hope your skies are as clear as mine.
Both little used, 'as new' condition, selling due to change of camera.
Price incl. shipment: Ha: £99; CLS: £49
These are compatible with Canon 5D / 6D, etc, here are the links for details on these filters:
During the 3 clear nights in a row, I had last week, I could not resist giving the Horsehead Nebula a go, using my Vixen VC200L.
Whilst imaging with my Canon 450D via APT, I could not make out the Horse's head whatsoever on my laptop screen, but I knew I was on target, because I could see NGC2023, at the bottom of my screen.
Anyway I was pleasantly suprised with this result after processing through APP and tweaking in GIMP.
Not the total failure I was expecting.
