Description

Another quick experiment for seeing how near I might point over the glow of Dallas Texas.  About 34 subs each for RGB and 95 L at 60 seconds.  Also 28x180s each for Ha and O3. Made the RGB and blended H&O into that and also a bit of Ha into the L before making the RGBL.  Clouds have returned so this one might be hard to get more data.

Used SW Esprit 120 with Riccardi reducer and QHY 294M camera.  633mm. Guided with asi290 mini through a SvBony 60mm guide scope.  Pixel peepers will see even without glasses that the corners are bad..  The spacing is probably about 3mm too far way from the reducer. I'm trying another solution tonight using the same TSRED80 that works so well with the TMB 80 OTA.  I'm hopeful.
