Above and Below: Mars night of 8/29/03, stack of 60 images above, stack of 25 below left; stack of 71 below right. Note the polar hood feature (the bright blueish area at the bottom). Mars was just about it's max size and brightness.

Mars is ~~coming~~ here! That bright red (orange-yellow) star you see in the south before sunrise is Mars. The red planet is closer to the earth in August 2003 (toward the end of the month) than it has been for about 60,000 years.

Above: Mars, taken 7/27/03. This is a combination of about 250 images taken between 3:30 and 4:15 a.m. The image on the right represents an effort to separate the color channels and to realign them. The image on the left comes from the same source and just ended up with a different color balance when processing was completed. Images graded, aligned, and combined in ImagesPlus, then processed in Photoshop including an unsharp mask set to 16 pixels.

Update 7/13/03: Got up at 3:00 a.m. this morning. The weather was clear, dry, and pleasant! I used the PS-One external monitor on my camera this time, and doing so seemed to address the battery drain/camera overheating problem I've been having. The image above right is a stack of 94 shots. The orientation was reversed to stay consistent with what others seem to be doing. Used my Celestron 26mm EP, various exposure times centered around 1/20s, otherwise same details as below. After resizing to 150 pixels wide I tried a variety of unsharp mask radius settings and settled on 15.0 pixels. The two images on the left are from the same stacks of 120 images processed differently in Photoshop. Basically I tried for a more neutral color balance on the middle image, where I didn't mess with the color balance in the one on the left. The 1st two images are reproduced in a smaller size, below.

Update 7/12/03: Had another go at Mars this morning at 4:00. Clouded out at 5:00.
Above images: Tak FS102, Teleview 5x Barlow, Olympus C4040 digital camera, Orion 40mm plossl EP. Two images on right are both combination of 10 to 15 images combined in ImagesPlus and processed in Photoshop. (The two on the left are from 7/13 and are stacks about about 100 images each and the notes from 7/13 apply.)

7/6/03, 4:00 a.m. Partly cloudy. I set up in my driveway and saw some intermittent good views, seeing a prominent and well-delineated ice cap, and some dark surface markings. Very small now, using my 3mm EP (273x). Started taking pictures. Naturally, when conditions improved briefly, the batteries in my camera died. The 2nd set, which are new, died after two exposures and seem to be defective. After that, the clouds came back. I put the stuff away and went back to bed!
