A look back in time – Messier 16 from July 2021

On average light (and radio) takes about 43 minutes to get from the Earth to Jupiter. On average radio signals travelling at the speed of light from Earth …

Mythbusting: Broadband imaging from INSIDE city limits

Myth: You cannot image from inside cities because the light pollution will make things impossible. TL;DR: Modern software and filter technology is game-changing for imaging in the city, even for broadband targets! Long form: Let’s take a bit of a deep dive into this. For many, many years it has been accepted truth that you …

A long time ago, in a galaxy far, far away.

Ok, as galaxies go, Andromeda is right next door at only 2.5 million light years. Light that reached my 61mm telescope earlier this year left shortly after the earliest humans learned how to use fire. In playing with some new software that uses AI and machine learning to reduce deviation due to the atmosphere I …

It’s fairly bright with an apparent magnitude of 4 but it does span a huge amount of space, about 2 degrees wide. It covers an area …
