Clearsky Scorpio Astro Ha+Oiii / Sii+Oiii 7nm Golden Dual Narrowband Filter 2\" For Sale

Up for sale a complete set of ClearSky Astro 7nm Golden Dual Narrowband Filter 2\". This is the collaboration edition with Scorpio Astro, and the optical specifications are identical to the original Scorpio filters.
I have only used this set for about 2 weeks, and they perform phenomenally well.
Crystal clear, NO scratches on the glass.Great halo control. I used them paired with my Askar 71F,no visible halos around bright stars.
There are a few tiny, minor dust motes/specks on the surface. I haven\'t tried to clean them myself as I prefer to leave the glass untouched (I am too paranoid to scratch it!). They can easily be cleaned off with a proper lens pen or blower if you know how, but they absolutely do not affect imaging performance.
I have recently upgraded to a 3nm Antlia HO+SO set, so this trusty 7nm set is ready for a new home. This is a fantastic budget-friendly entry/intermediate set for deep-sky imaging without breaking the bank for 3nm filters.
