Amazing, superbly put together. I'm sure that there are some who will simply say "PhotoShop"

Great perspective...it's no wonder I can't find my tools after I've used them...

And I thought I was big. Actually that's what I do as another hobby, imaging far away space "stuff" like nebulae, galaxies (some colliding), star clusters, exoplanets, a few planets, and other space stuff. I have a home observatory with roll off roof we built when we built the house and run a remote system in California at a place called SRO Observatories. I've also help setup numerous telescopes (24-32") at various universities and worked on setting up and getting operational their CCD imaging systems. This like woodworking is a hobby........I'm retired.

I read an interesting piece of data about UY Scuti, the largest star we know of. If light could travel around the surface of our sun it would take 8 seconds to make the rotation. On UY Scuti it would take 14 hours to make it around.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I'm always amazed when I ask people what our closest star is and they reply Alpha Centauri which is actually a star system. But of course the closets star is our own sun and named Sol. Other than it being the local star in our planetary system it's not particularly large or bright on the stellar scale. Luminous Blue Variable are far large and brighter but are a bit unstable either expanding or contracting almost constantly. Will it end in an implosion or explosion? It's anyone's guess.

This is interesting....it takes me 21 seconds to cross a major intersection in town. Longer if I have to dodge cars that are running the light.

Just Monday we had the Mercury transit of the sun and it takes solar filters to image it or a indirect method to view, such as projecting on a surface such as a white board held behind the telescope. I don't usually get into such events but it won't happen again until 2032. I did take my travel scope to Hatteras, NC while on our anniversary trip and managed a few images. Local atmosphere and of course the sun makes it a bit tedious but managed a few decent images. I also didn't take a proper mount but rather used my heavy tripod which was barely suitable but worked with some finessing. If you want the pictures are posted here https://astral-imaging.com/Mercury%2...it%202019.html The second image shows the effects of the local atmosphere. The total transit took over 5 hours but it became hazy after about 30 minutes and Mercury became mostly obscured although the sun burned through. These were taken with a DSLR camera (Canon T7i and Astro-Physics Stowaway refractor telescope) and not CCD.
