|I've written a second page for my description of lunar libration explaining some of the details that control when the libration zones become visible.|
|I have made a large-scale picture of the Moon at 5.3 days. This is linked from my picture of the 5.4-day Moon where I have corrected an important error.|
|A new, monochrome picture of M15, a globular cluster in Pegasus. Imaged with a Ritchey-Chrétien and guided with an ETX125.|
|Another picture of the rotating sky, imaged with a better camera and lens than before|
|Saturn reaches opposition on 29th June and the rings will still be fully open this year. But its declination will be slightly further south making imaging even more challenging. Here are my first pictures for the season.|
|In June 2018 a planet-wide dust storm engulfed Mars. On 27th July Mars was going to come closer than it had since 2003 making for a good opportunity to capture its surface details. However, would the dust obscure the features? So I decided to image Mars as often as possible before that date, and this page shows the pictures I obtained.|
|On 6th June 2018 there was a transit of Europa across Jupiter. I captured a series of pictures during the transit and that of its shadow.|
|I have joined the Doncaster Astronomical Society and so I can use their 14-inch LX200 which is a superb instrument for imaging the planets. This is my first attempt at Jupiter under less then ideal conditions.|
|My local astronomical society has a 14-inch LX200 which I have started to use to image the Moon and planets. Here is a picture of Gassendi as a first try.|
|In January 2018, a day before third quarter, I took pictures of the same area of the Moon as I did at the previous first quarter. On this page I show both pictures side by side.|
|A novel way to balance two telescopes on a single mount.|
|In 2014 we moved and I had the opportunity to have a new observatory. This is the story of its construction written as we went along.|
|The full saga of my home-built, roll-off-roof observatory.|
|I have been trying out a new idea for control of dew forming on the front of my LX200 and DSLR lens. This page describes the system and my results.|
