March 2002 Newsletter

The monthly meeting will be held on Friday, 1st March, at Timperley Village Hall, 8  pm. Graham Sinagola will be speaking on astrophotography.

Recent Events In the past month, there have been two visits to the observatory by a cub scout group from Stockport. The first event, on the 18th had clear skies, the 14’’ was brought out to observe with, and a slide show was given by Chairman Chris Suddick. Feedback from Richard Bullock was that both groups enjoyed the visits, but a shame the second visit wasn't blessed with clear skies. Approximately 20 ADAS members went to the National Space and Science Centre on Sat. 23rd. A computer failure at the centre caused some initial problems getting in, but the trip was a success, and enjoyed by all. Another visit may be organised for a midweek date, to avoid weekend crowds. Graham Cliff and Chris Suddick arranged an early meet at the obs earlier in February to connect the newly acquired web cam up to the 14’’, and display images on the computer. The good news is that everything is working OK, but unluckily, the sky was cloudy, and it was not possible to make any observations or record any images.


A Messier Marathon has been suggested for the coming month, as we will be presented with the best chance of seeing most of Messier’s catalogue in one night. Taking care to observe in the correct order, so as not to miss anything, it should be possible to obtain sightings of up to 100 objects.  Given usual dates for dark sky sessions, the weekends before and after the new moon, would be Saturday 9th & 16th March. As usual, call Graham Cliff or Don Utton on the day no later than 3 pm to confirm details of Location/times etc.


Roger Livermore has been in contact with Adam Davison of the Mersey Valley Countryside Management Department, with a view to organising an event at the visitor centre at Sale Water Park in May.  There are 5 planets close together in the western sky in May, and it has been suggested that this would be a good time to go and set up a variety of members’ scopes to view the planets. Facilities at the centre include a meeting room equipped with a digital projector, so the possibility is there for a presentation to be given. Roger has mentioned that the department will need to know whether or not this is to happen, so a decision should be taken at the meeting on Friday 1st. Given that the event is well attended by members of the public it will be a good opportunity to generate a little publicity for ADAS.
