Astrodon 3nm for 5nm
Hello all!
Yes, you read that correct, I’m looking for someone who’s wanting to upgrade from 5nm to 3nm 36mm unmounted narrowband (Ha, SII & OIII).
I’m getting back into mono imaging again soon and while using a F/3 astrograph im better with the wider band pass of the 5nm than 3nm. So, is there anyone wanting to make an upgrade?
