Welcome to my web site!
This version includes new images of the Moon, Venus, Jupiter and the Sun.
All of the images on this site are my own, taken using amateur telescopes and equipment.
As ever, I hope this encourages you to get out there and enjoy the treasures of our universe at first hand.
Best Wishes,

Daytime images of Venus at inferior conjunction
25.03.17 14:41 UTC
Very tricky to image Venus safely with the Sun only 8 degrees below the planet. Used the shadow of the observatory shed
as my shielding. The phase was only 1% and the apparent angular diameter a massive 59"! Used a basic Orion 25 red filter and Baader UV/IR rejection filter to dim the background blue sky. PGR Flea 3 CCD on my 20cm Meade LX200 SCT @ f/10.
Very turbulent air above the felted observatory shed roof.
Jupiter
This opposition of Jupiter occurred in Virgo and hence for the first time in several years, the great planet remained
south of the celestial equator and vulnerable to poorer seeing conditions.

The Great Red Spot has been quite a striking colour in recent years, so has the NEB and NTB.

Our nearest star, the Sun
As a keen solar observer, it is a lean time with sunspot numbers crashing as solar minimum approaches.
The decline throughout 2015 and 2016 was rapid.
