My grinding tool is making cool patterns!
You’re looking at water trapped under my 12" meniscus mirroe, and flowing between the channels in the home depot porcelain tiles on my grinding tool. Those tiles will grind flat eventually.

Taken using my 4.5" telescope and phone! Both Mars and Jupiter fit into telescope view!
Very annoying observing session. Tried to take photos of the ring nebula but missed; planet conjunction was extremely slightly out of focus and I didn’t see until morning, and I looked for but still couldn’t see M33. Couldn’t see any detail on mars by eye either; that should change as we get closer to opposition.

I saw the aurora! It looked like light pollution at first, and I only realized what it was when I noticed the underwhelming “clouds” were in a different place after ten seconds. An hour later they had slight tints of red and green and distinct ray-like shapes! Very cool. Phone camera picked up way more color and detail than I could see by eye, and long 8s exposures picked up even more.

I wanted to stack together multiple exposures to reduce the amount of sensor noise… and clearly this code has some precision bugs. but it looks really cool

Introducing “Finley”, probably the jankiest and most colorful eclipse imaging setup of all time. The only telescope I have which is enclosed (and therefore safe to use on the sun) is this donated finderscope, meaning I’ll have crosshairs in all my images. I’m taking pictures using my friend’s phone which he gave to me after the screen cracked. I designed a 3D printed adapter so it fits on the sturdy 3D printed mount I designed for the far bigger Hadley telescope.

A quick moon pic from my 3D printed telescope and phone cam. Some out of focus tree branches snuck into the top and traced some faint dark lines!

BEHOLD, MY FIRST STACKED ASTROPHOTOGRAPHY IMAGE!
This combines 20 1/2sec exposures taken with my phone through my 3D printed 4.5" telescope. You can see stars down to magnitude 12!! This is so cool.
Turns out I didn’t see a galaxy in my photos because… I was looking at photos of a non-galaxy. This is the ring nebula, M57. Oops.

I found this with the help of an amateur with a huge telescope and laser pointer so bright it looked like a line pointing into the sky. Looked like a dim circular smudge to the eye. Picture taken with the 25mm eyepiece, so I bet I could get an even better picture through the more zoomed in 6mm

Reminder to North and South Americans, there’s an eclipse today! https://www.timeanddate.com/eclipse/in/usa?iso=20231014 DON’T LOOK AT THE SUN WITHOUT SPECIAL ECLIPSE GLASSES, EVEN DURING A PARTIAL ECLIPSE! If you don’t have one, take a piece of paper, punch a hole in it, and look at the shadow. Trees or colanders with many holes will make very cool shadows!
