I see these units especially useful for capturing meteors etc considering the often reasonable results you get from doorbell cameras ... Alan

How big Is the universe?
Alien 13 replied to VirgoCluster25's topic in Physics, Space Science and Theories
I had always thought that the Universe was tiny, smaller than a photon or electron... Alan -
What does nothing look like?
Alien 13 replied to VirgoCluster25's topic in Physics, Space Science and Theories
I want to know how big or small NOTHING is too. 😋 Alan -
If I put my hand out the ISS window.
Alien 13 replied to Sunshine's topic in Physics, Space Science and Theories
I would be up for a dip into outer space for a few seconds, cant be worse than sticking hour arm into a hot oven or a freezer, things we do most days or even a flame.. Alan -
electric shock from mount
Alien 13 replied to alacant's topic in Getting Started Equipment Help and Advice
I treat this annoying tingle the same way I would noise in one of my Valve amp designs that have separate ground and signal earths tied together with a 1-10 K OHM resistor with a 10 nano farad cap in parallel with it. Alan -
'Fine tuning' the universe...
Alien 13 replied to ollypenrice's topic in Physics, Space Science and Theories
I remember shortly after my stroke many years ago that I began to smell colours which lasted for a few years and have wondered if for example an Alien species that processed the EM spectrum as sound or scent etc could develop a greater understanding of the Universe or Math's than us or is visualization on a PC screen or book the only way.. So complex math's without numbers or symbols. -
'Fine tuning' the universe...
Alien 13 replied to ollypenrice's topic in Physics, Space Science and Theories
Man created the universe we see today, without us time has no meaning so an infinite number of universes may have existed before this one.. Alan -
I understand the need for these things, I live in a UK city not far from the center and cant get full fibre broadband for another 7 years so could be tempted 😋 Alan

My needs are simple, a 70mm refractor with fixed 6x magnification and a correct image view with internal focusing, it should have zero CA or other defects and be nitrogen purged... It should also not have a commercial eyepiece in its construction as they all have some issues but should have a soft rubber eyecup assembly. The military have some and I was lucky enough to look through one a few years ago and nothing today comes even close to the clarity and colour of the pinpoint stars. Alan

Best Wide Angle Camera Lens for Aurora?
Alien 13 replied to Kryff's topic in Getting Started With Imaging
Samyang 14mm f/2.8, manual lens but one of the best or the 28mm version. Alan -
The ideal way of supplying 12V over long distances is by using the 4 wire method, two current carrying wires and two thin sense wires which all go to the mount, unfortunately few commercial power supplies have this. The method you are using does the same thing but with 4 wires the PSU senses the load so adjusts the output voltage accordingly showing a constant 12 or 13V on the display even though the actual output wires might be a lot higher.

It reminded me of your left field design for a focuser.. Good to have new ideas. Alan
