For sale is a full set of 31mm Chroma imaging filters:
- LRGB
- Ha 5nm
- OIII 3nm
- SII 3nm
Purchased about about 18 months ago, they are in pristine condition including protective packaging. These filters handle bright stars very well, without the halos which plague many other brands (especially for OIII). They are also parfocal which reduces the need to refocus between filters during imaging runs.
Selling due to upgrade to a full frame camera.
Most of the images in my
Astrobin Gallery were taken using these filters with an ASI1600mm camera and Esprit 120 refractor.
