Finding your target

Home Forums Spectroscopy How do you find your target? Finding your target

Hi John,

This is a common problem unless you happen to have a mount capable of very accurate pointing. You can either use your finder scope visually, or more conveniently, attach a small CCD or CMOS camera fitted with a normal camera lens on top of your scope so you can see the wide angle field to which the telescope is pointing on the computer screen. Within this you should be able to see your intended target. By working out where the small field you see in the Alpy guide camera is within the wider field from the piggy-back camera, you can work out how to adjust your mount’s pointing to bring the target into the Alpy guider field.
