second light report
Well last night was the 2nd time I got to use my TSA-120.. For a few reasons, I haven't been able to get it out the last couple of weeks.
The seeing was really good last night so I cranked up the magnification and OMG!!!... this scope produces great star images...!!! Achernar's Airy disk at magnification looked amazing!!! From 150-375x, I've never seen anything like this...!!!!! The lack of diffraction spikes really made it easy to see an apparently perfect airy disk. Stars just look beautiful!! Star colours seem to be presented nicely.
At 50x with averted imagination I think I could see mottling in NGC253 & NGC55 from suburban Melbourne. 47 Tuc. looked great & the scanning the LMC was fun at 26x. But I spent most of the time just looking at stars, because they look so nice!
However, not everything is perfect though... at 375x on Achernar, I could easily see false colour as the seeing caused the image to shift in & out of focus. In focus it seemed OK, but at 375x it's sometimes hard to tell whether the image is in focus or not due to the seeing.
Has anyone else noticed this with the TSA-120?
Am nonetheless very pleased with this exceptionally built scope.
Still don't have a hard case yet :-(
