Sunday Sun 14th April '19

For the third day in a row the morning was clear and bright, although it started out somewhat overcast and I thought the opportunity to image was lost. By 9:00 am, however, things had taken a turn for the better and the cloudy sky had miraculously cleared, although, as I found out when I got set up, the seeing conditions were only poor to mediocre. Anyhow, on the basis of some scope time is better than none, here are the results of my efforts.

A closer view of AR2738 started to show the limits of the conditions. So tempting to over-sharpen...

Then over to the red end and again the limits showed with some of the finer details unable to be resolved.

Compare this image with one taken a couple of days earlier taken using the same setup (150mm/ DS Lunt35 mod, Basler acA1920-155um and 2.5x Powermate) in which finer details are visible. Seeing and air clarity make all the difference. Click on the images for their best representation.
