Astro Tutorial #1.12: What is 'seeing'?

Hey folks,

today's video will be all about the technical term seeing:

What factors influence our observation session?
How do different seeing conditions look like?

We will discuss this topics by having a look at three images I took from Venus.
One with bad seeing – one with intermediate seeing and one with quite good seeing.

Join me on this trip to the planets!
Clear skies everyone!
Chris

I’m a rookie in this space. Your videos has been THE content I was looking for and I must admit, it’s very rich and enlightening. I’ve become your fan Chris 😇

I was tormented with bad images of planets for a long time until one day I was able to get details in Mars. It was then that I realised all my failed attempts were due to bad seeing, particularly high humidity of 95% and fast moving air currents. Thanks for the video.

Been binge watching your tutorials. Really appreciate these. Thank you.

Your channel is very interesting. In the last week or so I bought a pair of 20x80 binoculars, and (in England) tried them on orion nebula, light gathering was great, saw the nebula and stars within, but I couldnt get a perfect focus on it, or any stars or Jupiter, and began suspecting the optics were faulty. I tried considering cooldown time, dew, my eyes, and light pollution. No real change over a ccouple nights, but tI had been looking in large gaps between clouds. Suddenly got perfect focus, easily, 3 or 4 nights later, when there was no cloud at all. I believe the sudden improvement was partly cooldown time for the binos, but largely due to better seeing, which I had under appreciated. Ive added dew shields, a bino bandit, keep the binos in the garage instead of indoors, and will add dew heaters if the need arises. I have a good tripod, but am working on making a parallelogram mount so I can observe seated, version one needs improvements, so work continues. Subscribed;)

Great informative Video
Also @4:16 it looks a Bit like a Sad Face Venus :-)!!!

I assume the higher the angle up plays a part in the image, less atmosphere to contend with? Thanks again Chris. 🪐☕️

Hey Chris, I was wondering if you are considering making a discord server. I have lots of questions and i think that a community of passionate people is the best place to ask for answers!
Great job, keep it up!!

Aren’t you mixing transparency and seeing? Seeing is often good with high humidity, while transparency low.
One more thing, what is point of this video. You need to tell how numerically seeing is presented, how it is measured, etc.
