Well as usual I started out last night with great intentions but the gods of weather are detemined to give me woes

I started capturing with a couple of 3 minute frames to make sure everything was tracking and focused OK

Then switched to a 10 minute frame and this worked Ok then thought why not a few 15 minute frames

Left the mount unattended came out about twenty minutes later to check one good 15 minute frame so left it then came out about 30 minutes later and PHD had stopped somewhere inbetween due to as far as I could tell excessive dew build up on the guide scope.

Reset everything tried again and same thing happened. So I wrapped the guide scope in some towel and managed to capture 4 decent 10 minute frames in a row before the same thing happened again.

So I ended up with 1hr 15 minutes in 7 frames, 2x10 minute captured between 7.30-8:00pm a 15 minute frame just after 8:00 pm and 4 x 10 minute frames between 9 and 10 pm.

As expected due to tracking and fore mentioned issues this image has been cropped. Next on my list 2 dew heaters and controller.

Oh well you can only

Long dew shields and thick ones would serve you better for your guide scope Trevor.

Despite all the issues you still ended up with a fairly good image Trevor. Keep at it mate.

Thanks guys the feedback is much appreciated.

The guide scope has a dew shield but didn't seem to help last night

Paul a longer dew shield over heater straps works better
