Solar imaging – 16/2/16 (+ something unexpected)

As I have been very busy trying to make the most of all the opportunities to do imaging, I have not had the time to process these until now. It can be predicted that the clear skies will not last in England, and hence it is good to have things to process on those days when it is not possible to do imaging. Here are the solar images I managed to capture last week, including a surprise.

Equipment used:

Skywatcher ED80 with Daystar Quark (Chromosphere) with Baader UV/IR filter, mounted on iOptron ZEQ25GT, imaging with ZWO ASI178MM-cooled imager with Revelation 1.25″ 0.5x focal reducer connected to Microsoft Surface Pro 3. Sharpcap 2.7 used for image capture.

Below are the images from that day.

While imaging the sun, I noticed the sound of a helicopter flying past. I thought to myself how great it would be to capture it flying past. And lo and behold, I saw its silhouette flying past the solar disc on my computer screen. Here it is below.

The helicopter looks like a military one, and has two rotors, so likely a Chinook flying from RAF Benson, South Oxfordshire that day.

I am well pleased with the lack of the Newton rings now that I used the Baader adapters to mount the camera onto the Daystar Quark. Now the next step is to try and reduce the moisture inside the Quark, so that it does not impact on the image capture. And of course learn to colorise the solar images.
