Mewlon 250 First light

Posted By Alan Friedman
Hi Brian -

It takes a while to break in a new set-up. Keep at it - the Mewlon should be a great planetary performer for you!

FPS VS. QUALITY

Posted By Alan Friedman
Wes' comments are very true.

Another consideration under average seeing conditions is the benefit that can come from imaging at specific wavelengths to combat the air turbulence. In seeing conditions of 5-6/10 pickering It has been my experience that streams taken with a red filter show higher resolution than full visible spectrum streams or streams isolating the shorter wavelengths - even though the red filter required an increased exposure and 15 fps capture rate (instead of 30fps).

A final Jupiter

Posted By Alan Friedman
Thanks very much for the generous comments. I certainly hope to travel some in the next several years - tropical climates seem very appealing during our 5 month Buffalo winters 8). I wonder how to shlepp the equipment? I have driven the 10" mak down to Florida a number of times but it has always enjoyed a passenger seat!

I am headed to New Hampshire for a couple of weeks with a big family, a small scope and a sketchbook. I look forward to catching up with all of you and the Mars imaging season when I return.

best wishes -
