Subject: Mars images - Aug 23, 27, 31
I finally finished processing last week images, which I have attached. Overall, seeing has been poor with only the Aug 23 images revealing any amount of detail.
The Aug 23 images were taken at Starfest, a combined effort of Brian Lula, Gord Rife and myself. Brian Lula offered the use of his beautiful 20cm, f15 Maksutov while Gord and I captured the images and worked at processing. Seeing was good that night, and transparency as also very good. Solis lacus was placed on the central meridian and presents a wealth of detail. I slightly different set of filters were used with the portable filterwheel. Details noted on the image.
The pair of images from the 27th and 31st were taken with the 30cm SCT @f34 (standard Maple Ridge scope) and ToUcam with Schuler filters. Seeing was poor both nights, and I manually selected the best 10-12 frames from 450 in the video clip. Aug 31 images were slightly better. Both nights suffered from intermittent thin cirrus cloud, and I tried not to image while the cloud was present.
All images aligned and stacked with RegiStax and processed with MaximCCD.
Please let me know if there are any questions or comments.
