Venus, Oiii and CaK

I used my usual Venus gear: EQ3 with the added ST4 port, N150/750, filterwheel, OIII + VenusU and CaK, ASI 178MM cooled.

Venus, full spectrum

This time I used a very modest setup: the sky wasn’t promising, and indeed, the seeing was quite bad. So I put together the MC102/1300 with a barlow and an ASI 120 MM with an UV/IR cut, to capture Venus. Otherwise the unguided EQ3 did its job, given the lower magnification.

Venus 2020-04-22 and 23

The gear is the same, but I deployed a new workflow: I start the editing on the raw stack, before applying any wavelets. The reason for this is that Venus has a nasty habit of its edge going easily overexposed. The pictures are through the Venus U and the Ca K-line filters, combined with the OIII filter.

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

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.).
