Antares,globular cluster M4 & (part of) The Rho Ophiuchi cloud complex

20 frames taken 4/28/12

Experimented by creating a 2 pane mosiac

Conditions were poor, evident by all the noise. Planning to add more subs when conditions are better and correct halos and color around each star

Combined 5x300sec frames from previous version with a 2 pane mosiac 5x600sec/each pane-taken with ST-80, T3i and CLS filter

Added 5x600 sec Ha from T3 and 75-200mm lens f/5.6 (200mm)

2 hours 5 minutes

 

 

Telescope used: Orion ST-80(my "guide scope") mounted to 8" Meade LX-50 on standard Meade equatorial mount & HD tripod, Canon T3 w/ 75-300mm lens and Ha filter piggybacked on 8" Meade as well

 

Images aquired using APT
