Now for a real challenge...I don't see a lot of images posted of Mercury from any size scope, let alone images captured using small scopes, so it may be that this is not a popular topic, but it is possible to capture surface features with a small scope on Mercury, and I'm sure there must be someone else out there who has tried and has images to share.
Yesterday evening, Mercury was close to the crescent Moon, making it easy to align my Nexstar 6SE on the Moon, focus, and then slew to Mercury. The day before I aligned on the Sun, which was further from the planet in the sky, and had no luck finding Mercury (aligning on a single solar system body isn't very accurate). The resulting image is by no means impressive, but comparing to the WinJUPOS simulation, it does look like I captured some albedo features. I used an ASI224MC camera with 2x Barlow, ADC and 610 nm filter. Imaging time was around 6:40pm, and seeing was pretty terrible. I'd like to think that in good seeing, someone could do much better with a 6" scope.
