Moon with DSLR
Imaged the Moon with my EOS 300D DSLR behind the AT80 telescope and a barlow lense. Focal distance appears to be 1400mm, close to the ETX105, so the barlow factor is about 2.6. Moon fits in the image full-size.
Took 150 frames with the finest JPEG setting. Didn't do a polar alignment and total session time was 45 minutes. So I had to recenter the moon manually several times during the 45min framing session. I Focussed by eye through the DSLR viewfinder. This is not an accurate method so I retried the focus 3 time during the session.
Afterwards during postprocessing on the laptop the frames 105 up to 162 appears to be have sharpest focus. I stacked them in registax V5. The Wavelet function in Registax adds a lot of focus and detail, but one must beware not to overdo this.
