Venus 2020-04-20

Same gear, this time I pushed ten minutes into the CaK and also at around ten into the OIII, though for the latter without a particular reason (I forgot to press stop).

Venus in CaK and Oiii

The gear, as usual, was the N150/750 on a modded EQ3 autoguided by the soapbox project. As a camera, it was the modded-to-be-cooled ASI178MM, with an automated, originally manual filter wheel. I used the OIII and the CaK filter this time, to create to bicolor combo.

Same gear as before, too lazy to write it down yet again. The green and CaK filters got into this picture.

Venus, green plus calcium K

The same exact gear, it’s getting boring to write it down. Only this time, it was between passing clouds, quite annoying.

Venus green+U

The same gear, but now the fully automated filter wheel with its hand controller optionally connected to the soapbox project and the desktop app now controlling sharpcap — telling it which filter is active. This day the Venus U filter yielded the best result.

In fact, the pros and cons in my experience with Venus, two different barlow lenses and two different scopes, the N150/750 and the N250/1200:

filter pro con
Venus U brighter image way less sharp, could be due to the barlow not being optimized
CaK quite sharp darker image needing longer expos/higher gain

Venus with the U filter and the OIII this time

Same exact gear, except for using the Venus U filter for this shot. Was it luck or something else, this time the Venus U image was better than the Calcium K. Not the best seeing. So, the outcome is:

Venus

Same exact gear, but worse seeing. Also, it’s curious that the contrast on Venus has diminished somewhat.

Venus

Using the same gear as yesterday, the N150/750, the motorized filter wheel, the green and Calcium K line filters and the cooled ASI 178MM, all guided by the soapbox, I imaged Venus.

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.).
