When it’s close to a favourable opposition, Mars is a great imaging target. For best results you need a planetary camera that can record many still frames in rapid succession. These can then be processed using freeware programs such as AutoStakkert! or RegiStax. The larger aperture of telescope you can use, the better. Allow your scope time to cool before use, typically 1-2 hours (large scopes may need longer). When imaging, re-focus after each filter change and ensure focus is accurate.
A colour camera or monochrome camera with filters, eg, RGB (Red, Green, Blue), is ideal. However, colour can suffer from atmospheric dispersion, an effect that chromatically blurs detail. This worsens the closer you get to the horizon, fine detail becoming less distinct and colour fringes appearing, but these effects…
