Due to the very few light, exposure times needed to be at around >100ms and gain pushed to > 3/4 of the slider to get meaningful results.

7 Iris, 16 Sgr – 2020-07-09-10
I observed the asteroid 7 Iris’ close approach (though not the closest point) to 16 Sgr. These are some of my recordings. The autoguiding was done through a photo tele lens, as the main camera was exposing for seconds at a time. HEQ5, N250/1200, TSO ADC, ASI 224MC and ASI 178MM(cooled), home observatory, mountpusher

My Filterwheel Automation
Quite some time has passed since I automated my manual filter wheel, so now I write the article. I built this one mainly for fun, I could afford the (overpriced) automated version.
The specifications behind the whole idea
- automate the manual filterwheel — without modifying the wheel itself, revert the changes should I get bored or if anything goes south
- make it fail gracefully: the DC motor can be driven by anything outputting around 5V, a manual H-bridge and a couple of AAA batteries for example. Experience: the first version with the encoder failed due to the intense sunlight — hence duct tape and a paper cover of the window were added. Failing gracefully meant disconnecting the logic and connecting the manual H-bridge. No observation wasted.
- make it compatible with my existing gear (the soapbox and the noszogtató)
