Description
90 second unguided exposure at 400 iso using a Canon Digital Rebel at prime focus to my 5-inch f/7 refractor. Refractor uses Meade AR5 objective with 3.1-inch diameter ED Triplet APO f/7 condenser lens to improve color and widen field of view, converting AR5 to near APO performance. This combo produces a very flat field at prime focus - super for photography.
