Well, at long last I think I’m finally getting the hang of this autoguiding lark! The picture below is of M44, the Beehive cluster. It’s a stack of 16 x 2min exposures taken with a Canon EOS400D at ISO800 through a 8″ Meade LX200R witha a Meade f/6.3 focal reducer; autoguiding was done using a Starlight Xpress Lodestar guider through an Equinox ED80 refractor. Image acquisition and processing was performed using Images Plus 3.0.
M44 isn’t a particularly interesting subject, but it’s big and it’s bright – good for practising on! While I type this, the same set up is imaging globular cluster M3 in Canes Venatici. I’m keeping my fingers crossed!
Well, while M3 was being captured, the optics on both scopes started to dew up. I ended up with 10 x 2min images which were processed to give this image. It’s not as sharp as I’d like – more work on focusing required – but at least the guiding worked 🙂
