Since it’s relatively easy, I’ll start with the tools required. I think this is pretty much everything I needed for the first build. Covering the easy stuff first, obviously there’s the soldering iron. It would be nice to have a … Continue reading →

Robert Brown’s Arduino-based dew heater controller

Posted on January 16, 2020 by james

Like almost everything in my life, this has taken a lot longer than I was hoping, mostly because I ran out of steam a bit, partly thanks to the weather being so poor, but also because it took some time … Continue reading →

Posted on January 16, 2020 by james

A while back I posted an image of M27 and it was suggested that I grabbed some OIII data which would show up the outer wings of the PN. As almost no-one in the UK will be unaware, the weather … Continue reading →

A second attempt at processing the Crescent

Posted on January 16, 2020 by james

I’ve had another crack at this and I think it’s better in some respects, but I’m coming to the conclusion that I really have to get rid of the stars and process them and the nebulosity separately as trying to … Continue reading →

M27 revisited

Posted on November 9, 2019 by james

I first imaged M27 quite some years back and it has always been a favourite, so it being the summertime this planetary nebula was an obvious choice for an early target. This time I used the Skywatcher ED80 and Atik … Continue reading →

The observatory at work

Posted on November 9, 2019 by james

Work on the observatory has slowed somewhat as I need to catch up on other domestic jobs, but from the images I’ve already posted it’s obviously being used. I’m not sure I have the arrangement of mounts and telescopes that … Continue reading →
