I decided to try the DS 2.3+ with the PST-DS today for some solar imaging. I was hoping I would not have to use a Barlow lens to achieve focus, but unfortunately, I had to. The good news is that the large chip in the 2.3+ still enabled me to image pretty much all of the solar disc. These images are stacks of around 30 of the best frames from the captured AVIs. No other tweaks have been made other than stacking and wavelet processing; the color is as captured.
