2023/03/19

Below is audio of a piece I’m working on, called “Slow Blink.” The ring modulator on a synth comes in at 13 seconds. Schematic of the 4-diode design of a ring mod above. Has a sound like a broken bell. Without it this synth part sounds very clean, same as the synth that precedes it. … Continue reading "Ring modulator audio example"

MICHAEL W. DEAN ·

2022/12/28

Here’s my photo of M31 (Andromeda Galaxy), the closest galaxy to us. The many things marked PGC_____ are tiny (to us) galaxies that are much further away. Next to each catalog number is a little circle or cross point showing the location. In some you can actually see a tiny oval or dot. M31 is … Continue reading "I love those tiny (to us) little distant galaxies"

This is an area the size of about an American … Continue reading "My pic of Perseus Double Cluster (NGC 869 and NGC 884)"

How star tracker photo mounts work (polar alignment...

MICHAEL W. DEAN ·

It’s kind of fascinating, and this is how all tracker mounts work, even huge observatories. You point the base north. Not magnetic north, but geographic north. You mount it at an angle equal to your latitude. For me that’s 45.13 or as close as I can get. Then you use the sighter scope, a cheap … Continue reading "How star tracker photo mounts work (polar alignment scopes)"
