Lines of small sunspots

A Fujifilm Finepix S8200 Bridge camera was fitted with a Baader solar filter, set to ISO 100, f/6.5 at 1/1000s exposure and mounted on a Merlin, auto-tracking mount. The camera was set to its maximum of 40x zoom. Two sets of 10 images were captured in rapid succession in burst mode. The images were stacked in Registax 5 to produce the final image.

Star Party at the Garnswllt Activity Centre last night

Despite the fact that there was torrential rain as well as hail, the star party was a huge success. Brian Stokes's lecture was packed to capacity. In an adjacent room, Gaynor, Steve and Colin demonstrated GOTO telescopes to visitors. The cafe served refreshments and approximately 50 visitors enjoyed the show despite the weather. The success of the evening was due in no small part to the hard work, organising and marketing skills of Events Organiser, Emina Redzepovic, who left the Centre for pastures new after the event was over:

Brian gave an interesting lecture:
The room was packed to capacity:

Telescopes were demonstrated by Gaynor, Colin and Steve


A successful end to the night-time star party season.
The next star party will feature our own star, the Sun, at the National Botanic Gardens on May 24th

95% waning, gibbous Moon with Barlow projection

A Pentax K-x DSLR was fitted with a T-threaded 2x Barlow lens and placed in a low profile focuser of a 130mm, f/5 Newtonian on a Synscan AZ mount. The camera was set to 1/200s exposure at ISO 400. 10 RAW images were captured in rapid succession, of each of two overlapping images of the Moon. The images were stacked in Registax 5 and the two resulting images were merged into a single image. Click on the image to get a larger view:

The Sun in white light

A Fujifilm Finepix S8200 Bridge camera was fitted with a Baader solar filter, set to ISO 100, f/7.6 at 1/1200s exposure and mounted on a Merlin, auto-tracking mount. The camera was set to its maximum of 40x zoom. Six sets of 10 images were captured in rapid succession in burst mode. The best 48 images were stacked in Registax 6 to produce the final image Which shows AR2005 and other sunspots on the disk as well as prominent, faculae. Click on the image to get a larger view:
