A DMK21AS camera fitted with a UV/IR filter was placed at the prime focus of a Coronado Solarmax ll 60, BF15 and 5000 AVI frames were captured in 4 overlapping areas of the Sun. The resulting images were combined into a mosaic of the entire disk. The resulting image was colourised to represent the wavelength of light used to capture the image:

The lens assembly from a x2 Barlow was attached to the front of the camera and a region containing AR1410 and some prominences were imaged, exposed for the disk and also for the prominences. The two images were combined in Andrew Sprott's 'Solar Layers' software:

Prominences, AR1410 and a long filament were captured.

The IR/UV filter was then removed and the camera system was attached to a Ca K-line PST scope. The region of AR1410 was imaged. The resulting image has been colourised to represent the wavelengh used to make the image:

AR1410 is clearly visible as is the chromospheric network of high magnetic flux.

A Pentax K=x DSLR was used with a 20mm Plossl for eyepiece projection and the solar disk was imaged:

This is not an easy technique, but with practice, should yield acceptable images,
