LtE in CMO #240

From Frank J MELILLO

@. . . . . . Here is my first image of Mercury since June of 1999. It was taken about 15 minutes after sunset. The seeing was just below average. But, I got only one good image when the seeing stabilized for a few seconds.

I might detect some markings from the terminator to the limb on the north side of the disk. I was wishing to take more images but already it had passed behind the trees. I am planning to take more images of Mercury during the favorable evening apparition in May.

@. . . . . . I am trying not to leave Mercury out. Last Saturday, I managed to get a fairly good image with a Wr. #25 red filter right after sunset. This time I was more prepared, but it was a lot more difficult than on 1/28/2001. Again I had very little time left before it went behind the trees. Unfortunately, no details visible which I already expected that when Mercury appears as a crescent.

 Also on that day, here are my latest images of Venus in UV light. As you notice, the details are getting finer and finer due to the increasing apparent diameter. What happens when the details spread out, this lowers the contrast. This works the same way with the deep-sky objects. Regards,

@. . . . . . Finally, I took my very first image of Mars for this 2001 apparition. The seeing was quite good for hi-resolution. At CM - 313 degrees with a red filter Wr. #25, Syrtis Major is clearly seen while Hellas is quite dark. NPC is difficult to see. But, there are numerous details around the North Polar Region.

 It will be posted in the Mars Watch 2001 web page.
