Imaging and Image Processing with a High Frame Rate Camera

Imaging and Image Processing with a High Frame Rate CameraMick and I talked at the Cambridge Astronomical Association about Webcam Imaging or really nowadays High Frame Rate Camera Imaging on Wednesday 21st June 2017.

The talk covers a brief history of webcams and high frame rate cameras, it then covers setting up your camera and using camera filters as well as looking at Field of View (FOV).

We look at using camera software for capturing the images, including  Sharpcap and Fire Capture. We also looked at Registax 6 and Autostakkert for processing and the usual Photoshop and Microsoft Image Composite Editor (ICE) for making lunar mosaics.

Included in the PDF are some of Mick’s best solar, lunar and planetary images.

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.

A and F Type Stars Talk

On Saturday I did another talk for the Cambridge Young Astronomers. This months topic was covering the Hertzsprung–Russell diagram and explaining all the different star types within it. I was given A and F type stars for my talk.

Hertzsprung Russell Diagram

I started by looking at the Hertzsprung–Russell diagram and then gave facts on A and F type stars. I then picked an A and F type star example and explained more about the stars. My example of an A type star was Vega and my example of an F type star was Polaris.

I have put a copy of ‘A and F Type Stars’ talk on the downloads page if you want to have a look at it.

The Moon by Eye, Binocular and Telescope

On Saturday I did another talk for the Cambridge Young Astronomers. This months topic was our nearest neighbour. I chose what you can see on the Moon by naked eye, binoculars and telescope.

I started by looking at the main seas or Maria on the surface of the moon that you can see with the naked eye. I then went onto looking at lunar craters including Copernicus, Kepler and Tycho. I then showed an image of their location on the moon as well what they look like through a telescope.

I then moved onto looking at the Apollo landing sites and looked at Apollo 15 landing site at Hadley Rille with an image that I took on my 8″ RC telescope. I then showed a quick video of the phases of the moon which were sped up to illustrate the best time to view the moon along the terminator line.
