Mars is currently slightly above 5 arc seconds and as I'd been clouded out for a week or so, I couldn't resist seeing what I could see.
The image at X170 was simply too tiny to make any real sense of in my small scope, though dark albedo markings were visible. Increasing the power to X340 increased the image scale to a good size for studying. I had no preconceived idea of what the LCM was, and thought at first I was seeing Sinus Meridiani and Margeritifer Sinus, but I was wrong!
After working out the meridian it became clear the dark feature just below centre is Syrtis Major and the bright spot to the left of centre is Hellas. I used a prism diagonal just to confuse everyone! ![]()
Not too bad for a 100mm scope! ![]()
