 Post subject: CCD vs DSLR
PostPosted: Wed Feb 20, 2013 4:02 pm 
Hi all,
I've been thinking of upgrading my imaging systems, namely my canon eos 1100D & my Philips SPC900 guide cam.
I was looking at the Canon 600D with a view to getting it modified for astronomy. The cost for this upgrade & mod are (forgive the pun) astronomical!

Instead of spending upwards of £650-700 on a camera, I was wondering whether a dedicated CCD would be a better option.
I've really no idea about them except at 1st glance they're a really expensive item!
What I want to know is
1. Are they better than a Canon (by that I mean pound for pound more value)
2. monochrome or colour (Why you'd choose monochrome over colour)

sorry if this seems a bit daft, but it may clear up a few things for me.
The very fact that Dave & Gerald use a Canon may already provide me with all the answers to my question!!!
Cheers
Andy

Andy,
The way the most have gone on cameras is a secondhand already modified Canon camera. These run around £200 to £400 depending on model. The latest ones with multi-megapixels are not a step forward.
As regards an astronomial CCD camera it is not just the cost of the camera. To benefit from their performance long sub-exposures typically 10 to 20 minutes are required. Having a mount and guiding system capable of supporting them is essential. The real advantages are only achieved with a monochrome sensor - using the LRGB method. This brings a level of complexity both in taking and processing way beyond the "simplicity" of a one-shot Canon. It is a step to be taken only when the imaging bug bites deep and all the pieces of the jigsaw are in place. I should also add that cooled astronomical cameras and the Lancashire climate don't agree - only one manufacturer (the most expensive of course) builds one immune to our damp.

Thanks for that Dave,
I'd presumed as much, but wanted to be sure prior to he wallet being significantly emptied! I will hunt around for an older model canon already modded for astronomy.

Cheers
Andy
