The Sun in Hα – 2021-08-15

The Sun in Ha

The Sun produced a really nice vista on this day, somewhat continuing yesterday’s visual feast. Observing with ASI 178MM (cooled), B600, Lunt LS60T Ha, mountpusher, EQ3-mod, these are the results.

The very high dynamic and the intricate details demanded compositing this time, even though I know the details change over time. Life sucks, live with it.

Venus 2021-08-15

Venus, 2021-08-15 through a solar continuum (green) filter

Alright, let’s go after Venus with whatever I have at hand. The local time is 16:45 (13:45Z), Venus is at around the meridian at around 45 degrees high. Behind a brightly lit blue void. The available rig: ASI 120MM (cooled), Baader Solar Continuum Filter 1.25″, barlow lenses, TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod. Fun part: the bright sunlight and the bright blue sky made it next to impossible to spot Venus, using a mount that’s not properly aligned, thus almost no coordinates. However, I cheated. I used the Sun — fairly easy to find — to get an idea about the RA of the unaligned mount, drew lines onto the mount (it has seen worse), and I hacked together a few lines of arduino with a dev board and an MPU 9250 to show me the attitude of the scope. Have I mentioned how handy these little ESP32 dev boards are, and how arduino in general solves decade old problems, making the pedestal of obscurity embedded is in general shake a wee bit? However, I feel literally, physically tired of having to outsmart and circumvent, or just brute force every possible issue the universe (or better call it real estate maffia, then govid-19, among other issues) has in store for my hobby. Given the instruments, this picture is nowhere near the quality of my epic Venus season.

I took a total of 27 individual recordings, and stacked the best 300 of each into one picture. ASI 178MM (cooled), Baader K-Line Filter 1.25″ (double stacked), TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod

The Sun, Calcium K, 2021-07-25

This time, a rather aggressive processing, maybe for the better, who knows.

The Sun in K 2021-07-24

This optical tube is a marvel, at least with the Calcium K filter. Although there are some stacking-aligning issues left on the picture above, it is still the best I have ever made.

2021-07-22, K-line Sun, first light

This is the first light of the APO tube I just bought, and put into the lunchbreak-heliobservatory: ASI 178MM (cooled), Baader K-Line Filter 1.25″ (double stacked), TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod

I really like the design of the tube, how short it is, though its focal length needs either an expansion tube or the flattener, which I figured wouldn’t be a good fit for the Sun.

The tiny additions I put onto the tube: the focuser and the cardboard adapter for the ND3.8 filter I already have for the MC102/1300.

It was a really nice surprise to see the Sun in much more detail, than through the Canon EF 200mm f2.8L II USM

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.).
