99% waning, gibbous Moon

A Fujifilm Finepix S8200 Bridge camera was set to ISO 100, f/7.6 at 1/640s exposure and mounted on a Merlin, auto-tracking mount. The camera was set to its maximum of 40x zoom. Five sets of 10 images were captured in rapid succession in burst mode. The best 45 images were stacked in Registax 6 to produce the final image. Click on the image to get a larger view:



Four hours later, the camera was set in B/W mode, f/6.5 and 1/800s exposure. 40 images were captured and stacked in Registax 6 to produce the final image:


The second image is rotated with respect to the first because an AZ mount was used.

SAS on S4C Dibendraw

A team from Swansea Astronomical Society helped Dr Rhodri Evans with the filming of part of a Welsh language space and astronomy program on S4C Dibendraw (Infinity) produced by Telesgop Productions. These scenes were filmed in infra red light at the National Botanic Gardens of Wales.








The team comprised Rhodri Evans, Nicola Mackin, Colin Miles, Keith Davies and Steve Wainwright.
The program was screened on Wednesday February 12th. The following link should work for a few days. English subtitles are available:
