Hi,

I have only used PHD2 with a widefield (SVQ100) scope until just recently. With the SVQ100 I have had no problem with finding stars or the brightness of stars.

Recently I have started to use a C11 Edge @ 2800mm. I an finding that the stars are a lot dimmer and fewer of them. I have been having "Star Mass Loss" issues as well. I have tried binning the Ultrastar to 2x2 but it doesn't seem to help a lot.

I am using 5 sec exposures....should I up that to ten seconds to try and get a brighter star? What settings would help improve the Star Mass at this FL and configuration?
