Rosette Nebula RASA8 - a photo on Flickriver

            Here's the second in my series of objects shot with the RASA8 during our recent clear stretch (also from my light-polluted backyard).

Taking flat frames with the RASA turned out to be very easy: After I parked the scope (towards Polaris and safely away from the Sun!!), I just shot my flats pointed right at the clear, blue sky.

The advantage to this method is that it's incredibly simple - no need to set up a flat panel or figuring out how to get a flat panel to sit on top of the gear at the front of the RASA. The disadvantage is that your color balance will be MAJORLY messed up in your calibrated frames. Fortunately, you can recover the white balance in post-processing. :-)
