I'm primarily a VS observer, having started at age 15 or so with delta Cephei, with a subsequent primary interest in cataclysmic variables. More recently I've taken an interest in exoplanet transits, imaging small satellites in the outer solar system, the photometry of extra-galactic variable stars, and (to my surprise) imaging globular clusters and especially those not in our galaxy.

In the summer of 2018 we bought Tacande Observatory which houses a 40cm Dilworth-Relay telescope. Because the relay lenses in a Dilworth tend to scatter light, albeit not very much, it is not particularly good for observing bright objects. It seems to be particularly good at picking up things below 20th magnitude ...

Another in the series of images of small satellites in the outer solar system. Pasiphae is about 60 km in diameter and was at magnitude 17.2 at the time of observation. The thirty 1-minute subs were stacked on the predicted movement of the satellite, which is why it appears circular and the background stars are trailed.

Both Pasiphae and Sinope (image at are believed to be fragments of a single asteroid which was captured by Jupiter in the distant past.

Saharan dust illuminated by a full moon resulted in a rather lower-contrast than I would have liked.
