The principle instrument is a 250mm aperture, f/7.9 Ritchey-Chrétien telescope (GSO RC-10) on a Software Bisque Paramount MYT robotic mount. Guiding is via a ZWO ASI290MM camera on a piggyback 30mm aperture, f/4 guidescope. The primary camera is a QSI660ws-8 CCD with an 8-position filter wheel (open, luminance, red, green, blue, Ha, O3, S2). Focus is managed by an Optec TCF-Si.
The camera operates at a pixel scale of 0.46 arcsec/pixel (normally binned to 0.93 arcsec/pixel) and a FOV of 21.3 arcmin x 17.1 arcmin. The guider operates at 4.95 arcsec/pixel, and typical guiding is around 0.1 pixels, which is less than half of our best seeing conditions.
I have fairly recently started using PixInsight for the bulk of my image processing. For many years I've used Maxim DL for this, but it is really showing its age (and is ridiculously only available as a 32-bit application). While PixInsight has some conceptual design issues I consider questionable, there is no doubt that it is vastly more powerful than Maxim for image processing, utilizes much more modern algorithms, and does not require a subscription to maintain the latest version.
In some cases I use FITS Liberator or DS9 to achieve precise transfer functions. Final processing is usually in Photoshop.
