Lunar Imaging and Widefield Imaging Talks

Last night I did a quick couple of talks at the Cambridge Astronomy Association on lunar imaging and widefield imaging using a Geoptik CCD to lens adaptor.

The lunar imaging talk covered the top 10 tips when lunar imaging, a demo of stacking a lunar video using Autostakkert and Registax. I then also talked about how to complete a lunar mosaic by using Photomerge in Photoshop and Photoshop Elements or in the free Microsoft Image Composite Editor (ICE).

The widefield imaging talk concentrated on my use of the Geoptik adaptor, but I also introduced the other Canon and Nikon lens adaptors that are on the market. I then mentioned filters, backfocus and focusing. I finished up showing some Ha example images that I have taken.

The Sun in Hydrogren Alpha with Coronado PST

This image of the Solar disc was taken on Saturday 6th July 2013. It was taken using a standard Coronado PST and an Imaging Source DMK21 AU618 Mono camera. I did use a Short ‘C’ mount adaptor in order to allow the PST to gain focus, without having to use a Barlow lens.

As the DMK21 is only 640×480 I have to take 4 videos and then process each one in turn using Registax 6. I then imported them into Photoshop and used the Photomerge software to align them all up into one image. I then gave the mono image some false colour.
