I took following photos through my Daystar Hydrogen Quark filter, with different settings on the dial on the filter. This dial varies from -5 to +5, and I wanted to see whether photos were better with one or other setting – those settings vary the tuning of the filter.
- Sky Watcher Equinox 100m OTA
- Daystar hydrogen alpha filter
After this analysis, I am still not sure which setting is best! However, visually, and also Damian’s previous assessment, was that setting -5 was most effective for my Quark H filter.
it is worth saying that these photos were taken before I sorted out the flat frames on FireCapture, and the alternate dark and light banding in the photos shows (Newton’s Rings).
