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)

The Sun in CaK

I put together a rather modest setup: the Canon EF 200mm f/2.8 L II USM telephoto lens with an ASI 120 MM camera, and the CaK filter that has given me so much joy while observing Venus, all mounted on the EQ3. The goal wasn’t to image something never seen before, but just to blow the dust off my astronomy gear. I am lazy so I don’t like moving the dovetails around, and I  had a piece of hard wood — a dovetail it became.

Jupiter 2020-05-18

Just an early morning Jupiter, with my usual planetary gear, HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher Acceptable seeing but poor transparency.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
