What are the advantages of remote observing? • Altitude • Latitude • Longitude • Avoiding light pollution • Technical support • Taking on new astronomical challenges • Wide range of telescopes and filters to chose from
Altitude The five telescopes in the RAS Observatory are sited an elevation of 2225 metres in the high desert - close to Apache Point Observatory – and well above most atmospheric pollution. Latitude and longitude • Location: 31 miles east of the town of Alamogordo, New Mexico USALatitude: 32° 54' 14" Longitude: W 105° 31' 44” • Time Zone: GMT -7:00 New Mexico.
Latitude and longitude - continued Just compare the view of the southern sky! HORIZON RAS Observatory view – 32N My home town – 52N
Light pollution • Alamogordo, the nearest large town to the observatory, has one of the strictest light pollution ordinances in the United States. If you fly over Alamogordo at night, it is almost invisible, so effective is its battle against light pollution. The State of New Mexico takes light pollution seriously too and in 1999 Governor Gary Johnson signed the nation's strictest state anti-light pollution legislation.
Technical Support • Most observers have little interest or aptitude for “tinkering” • If something breaks they want/need/would like somebody else to mend it! This is exactly what happen at the RAS Observatory. New Challenges • Members wanted the chance to do a far greater variety of astronomical activities than were possible with their current equipment.
4 versions of M20 – each taken through a different telescope in the RAS Observatory
The types of projects members have done • Using standard (RGB) and exotic (H Alpha, SII and OIII) filters to image both well known and less well known objects. Rosette Nebula - Monoceros
Veil Nebula - NGC 6992 20 minutes in H Alpha, RED 20 minutes in OIII, GREEN 20 minutes in SII, BLUE
Crescent Nebula – NGC 6888 in Cygnus Magnitude: 10.0 - Size: 18.0'x13.0' 40 minutes in H Alpha
Hydrogen Alpha S II M42 and M43 These well known objects looks very different at three different wavelengths. In each case the exposure was 40 minutes. O III
Red = Ha, Green = OIII, Blue =SII Red = Ha, Green = SII, Blue =OIII
