Welcome to my web site! This latest version includes an image of a long dark filament on the Sun plus a
sketch of M7 from southern England.
All the images on my site are my own, obtained with relatively modest telescopes, cameras and filters.
As ever, I hope this encourages you to get out there and enjoy the treasures of our universe at first hand.
Best Wishes,

Long, dark filament on the Sun
22.8.10 09:11 UTC
Although there were no sunspots today, the Hydrogen Alpha view was more interesting.
Orion 80 ED Apo refractor SKYnyx 2-0M CCD; Coronado SM-40 double stacked filters < 0.05nm passband.
Open Cluster M7, Scorpius
This was sketched on the nights of 11th and 12th August 2010 from Charmouth, Dorset whilst
on holiday with the family. The altitude of this southern cluster varied from 4.2 to 2.9 degrees
during the course of the drawing, and the sky was not fully dark either! At the caravan park in Dorset,
I was almost as far south as you can get in England at +50 44' 07". You may know that M7 is at a very
low declination of -34 49', so even from this site it does not attain an altitude greater than 4.4 deg.!
Telescope: Megrez 80mm triplet apo refractor, x24, on simple camera tripod.
I thoroughly enjoyed four clear nights, just lapping up the dark skies by naked-eye and through the
80mm refractor! On the night of the Perseids maximum, the limiting naked-eye magnitude at the
zenith was 6.6 - 6.8, with Uranus and M33 glimpsed without optical aid. My 13 year old son, Jack
and I counted exactly 100 meteors between 22:10 and 23:10 UTC and a further 89 between 23:10
and 24:10 on the night of 12/13 August - we were both facing in mostly, but not entirely, the same
direction.
