Description

I got a nice Rosette image with the HyperStar 9.25 and ASI2600 monochrome camera, with H-alpha and OIII filters, so I decided to shoot some higher resolution "luminance" data with the Esprit 150 at f/7. The focal length is almost exactly twice the HyperStar 9.25 so the HS data would be like binned color. I shot through the Optolong L-eXtreme filter, even though I was using a mono camera, because it would get both the Ha and OIII data for the luminance channel.
