Imaging setup

Nice to read the different approaches to imaging. Here's mine for what it's worth. Like Ross, my setup is out in the open although I have a couple of USB leads from the PC inside to the scope. My EQ6 mount is permanently set up and aligned using Polemaster. All to save setup time. I'm lucky in havin...

Star count

There's still time to take part in this year's Star count provided we get an hour of clear sky.

Untried filter

Last night was my 1st imaging session since April & 1st try of a CLS-CCD clip filter. The BG in iris reads 2820 which seems a bit high.
Three hours so far and hopefully add to it tonight or Monday to pick up the faint galaxy cluster adjacent to NGC 7331. Bill C

Re: Light Pollution Gradient Removal

Not much saving to do Bill. I've had the program for a while and seem to remember it being less than £30. It's as good as David says. BillC

Re: The first night of the winter?

I hope your Tuesday night forecast is the accurate one. The 'Clear Outside' site says high cloud rolling in around 9pm

Hi Ross. I would find it useful at my caravan and would be happy to make a donation to the society. Bill C
