Hi. Just joined the forum and looking for advice. Living in Spain so have about 300 days clear skies per year. Astophotography is my main interest.
I have decided on the CG-5 mount as it can handle a wide range of OTA's and has "go-to". I would like a 100mm APO refractor, but not yet as funds are tight. So I was thinking of a smaller, cheaper (70mm or whatever) which could be used as an autoguider at a later date. Current buget for this OTA is €700 (including IP's finder etc). I have a small DSLR and a microscope CCD which will be used. Any advice on this would be appreciated.
Some supliers list a reducer/corrector for photography. Why would I need this on an APO? Thanks, Ed
