Venus, false color

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.

Venus, false color

Again, nothing new, same old gear, but I replaced the red/infrared filters because I suspect that my barlow lens is not permorming well with the wide band filters. So this time, green is the new orange, and the Calcium K line remained, as I like it better than the Venus U, at least for this setup.

N150/750 on the modded EQ3, the soapbox autoguider, ASI 178 MM with cooling added. I was looking at the amount of boxes I put together, and it’s starting to eclipse the “original” gear.

Venus, OIII + Calcium K

Nothing fancy, it’s just that my filter wheel arrived, and using the gear from an old printer, and a dc motor with a reductor box, I motorized it before even its first use. It’s still manual in the sense that there is no sensor to stop the wheel, it just goes one way or the other. Instead of the red channel, this time I used an OIII filter for the orange, and the cyan is still the Calcium K, as I like it more than the Venus U. The seeing, well, could have been better.

So the gear: N150/750 on the modded EQ3, the noszogtató autoguider, filters, ASI178MM modded (cooled)

Nothing fancy here, just using the same gear with the same settings. A slightly improved szappantartó autoguider and the knowledge that that mount is, in its current mechanical state, simply incapable of not sliding a few arc minutes from time to time, be the reason a backlash or tension building up and then being released.

With this PITA-19 I am more than limited, so I must settle with the N150/750 on the home modified and auto-guided EQ3. Using the Calcium K line, the Venus U and a simple red filter, I obtained the following pictures. The seeing was varying, with good moments and very bad periods. The best frames I obtained with the Calcium K filter, so the final color image is K as luminance over red as orange and K as cyan. The camera, as usual, was the ASI 178MM, no cooling this time.

The session spanned for more than two hours, so I had enough time to see the clouds move.

While this madness-19 is bit by bit closing down the planet around me, the sky is still free and safe to explore. So I pointed my light instruments, the N150/750 mounted on the modded EQ3 towards Venus, again, using the Venus U, Calcium K-line and Red Baader filters with the ASI 178 camera.

Nothing fancy, just working like a dog to obtain this picture. Unfortunately Venus is not available any more from my balcony observatory.

With the small gear, I imaged Venus. This time, the U filter delivered the best image, as a combination of the seeing and timing and the height of the planet. Modified EQ3, soapbox, N150/750, ASI 178 MM cooled, Baader Venus U, Red and Calcium K line filters were used during the session. The final picture depicted here combines the U filter as luminance, applied on top of the red as orange and u as cyan false color.

Using the experience gathered from my balcony observatory, I tried the old gear: the N150/750 on the now modified EQ3, and targeted Venus with several filters and the cooled ASI 178MM. Most pictures came out to be garbage, but some were good enough to start mixing them together. So I created a Calcium(Red-Calcium) bicolor image. Red became orange, the Calcium K line became cyan, and the Calcium K was applied once more as a luminance layer. It was kinda the first light for the ST4-enhanced EQ3 with the soapbox-guidance.

Venus

I imaged using the HEQ5, N250/1200, ASI 178MM (cooled), home observatory, mountpusher gear, aided by a red, Calcium K-line and a Venus U filter, all three from Baader. I used the red as orange and the U as cyan, to create the false color RGB picture, applying the K-line as a semi-opaque luminance layer on top.

With each passing day, the planet moves more and more out of the reach of my balcony observatory, these days the best horizon, the aperture being already partially covered by the corner of a wall, is at around 17:10 local time.

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.).
