Convection Cells, Chromosphere Network, Full Disc | HighRes | Sept 11th 2019

Post by MalVeauX » Wed Sep 11, 2019 4:25 pm

Hey all,

Had a clear sky this morning and playing around with some new configurations. With some help from members of the forum in the mod board I have tinkered up a little different PST mod that involves a straight through configuration using the stock blocking filter. Anyhow, it works as a standard PST but without the black box, and as a typical PST mod that inserts into another scope, such as my C8 Edge. Tested everything today with an ASI290MM.

Good set of images, Marty. Your experiments with the design have worked out nicely.
