PST with red color filter
The redesigned PST has a clear objective that allows all of the sunlight to pass into the telescope, whereas the original design had an opaque objective which I guess blocked most of the light at the objective.
With the aim of blocking much of the unnecessary wavelengths, today I tried a 2" red color filter in front of the objective. I had difficulty seeing a difference between the two images. Wondering if anyone else has tried this?
