Hi all,
Second attempt at Saturn. Thanks heaps to Matt and Jeanette for the advice
Conditions were much better last night and I was able to capture a LOT of data.
Anyway, here is my preliminary processed image. The first image is processed in Registax only. Second image is a good raw frame.
Paying careful attetion to the exposure during capture (as Matt suggested) worked a treat. I tried to keep it around 200 by adjusting the gain while keeping the exposure long. Decreased the frame rate to 15fps and used the automatic white balance (all as suggested by Matt).
Thanks to Jeanette, I went the 2x enlargement during frame alignment in Registax. I assume this is better than doing it at the end.
I realise this preliminary image is probably overprocessed, but I'm learning and have enough data to keep me busy for a while developing processing techniques now.
Thanks again for your help guys. Any comments, criticism, reprocessing most welcome. I'm trying to get better at this.
Celestron C8 with 2x Ultima barlow for 4000mm focal length;
Philips SPC900NC webcam at 15fps;
Stacked about 600 of 1000 frame in Registax;
Slight wavelet processing in Registax;
Slight final processing in Registax.
I'm thrilled at the detail captured in this image
Have fun,
Doug
