02/23/2008 - MARS: LX200 DSI PRO II

With Mars shrinking rapidly in size, I've about lost hope of capturing a significant image of the dwindling planet. After a very clear, bright day, clouds began moving in soon after I began capturing sequences of Mars images - typical of the Pacific Northwest. Here is the best result from tonight, a tiny, fairly sharp image of the tiny red planet. With the 12" scope out of commission while a pier is being built, the 8" is all I have available for imaging right now. This photo was taken with the 8" Meade LX90 and a Meade DSI Pro II camera.

02/18/2008 - RED MARS

Here is another disappointing attempt at capturing Mars. This image was acquired early in the morning on February 18, 2008 from Port Orchard, Washington, using an 8" Meade LX200 and a Meade DSI Pro II. Seeing conditions were not bad but my alignment was, making it difficult to keep the planet steady and in the FOV for optimal focus and processing.

02/12/2008 - DEWY MARS

The day was unseasonably warm and clear, so I thought that if the weather held, I might be able to get a few hours in with the 8" LX200. After setting up the telescope and doing a quick and dirty polar alignment, I was surprised to find that for the first time in my life, I'd hit precise alignment dead on, right out of the box! It was a great night of viewing, as the telescope tracked perfectly. I started imaging, moving between Mars to M42 and back, as I went through the trials of focusing the DSI Pro II. As I started to get near perfect focus, it became more and more difficult to keep the image sharp. Puzzled, I scratched my head and continued to work on the focus, slewing from bright to dim objects, back and forth, exposing Mars, slewing again, etc. Finally, I took a look at the corrector plate and saw a solid film of dew! I have a heated dew strip but the day had been so perfect that I had thought I would have no dew problems. WRONG! After only 90 minutes, I was done for the night. Above, you'll see a horrible photo of Mars, but it was the best I could get through the dew. There's always next time. That's how it goes here in the Pacific Northwest - you can wait two months for a clear night and then have it derailed very quickly if you get in a hurry or get careless - which is what I did tonight.
