Yup, sadly this sounds like (another :( ) poorly performing Quark.

Like Rod says, contact Daystar. Good luck :(

Yes. A t-2 extension that is 80 to 100mm.

Re: January 18 2021 Observations

Thanks James, nice report, glad we have a bit more to look at. Storms here for a couple of days then forecast to brighten up at the end of the week. I might see if I can have a working at home day on friday for some cheeky lunchtime solar. I see what you mean when you said how green the grass was in...

I don't think you will go wrong with that Basler 640 camera Alfred, sage advice from justapictureposter.

Re: Sony IMX253 mono cameras

what type of power supply and cable do you use to separately power the GH3 ? Hi Franco, I use one of these GPIO cables and just connect to a 12v lead acid battery I power the mount with. http://astrograph.net/epages/www_astrograph_net.sf/en_GB/?ObjectPath=/Shops/www_astrograph_net/Categories/Shop/P...

Looks good to me Bob, if a power supply feels heavy that is normally a good sign.

Re: what should I expect to observe visually these days? (H-alpha)

Like Rod says, stop using the 0.5x reducer, just use the 40mm, 32mm or 25mm plossl. The graphic below shows what you would see using TV plossls.

Re: Sony IMX253 mono cameras

The USB hub you posted Bob and the power supply later would definitely be an improvement on the WallWart power supply. I'm guessing your mount has 12V going to it Bob? Whats the source here? Liking the system! :) That's cool Franco you worked with Cello with ML, I know them. My 2 channel upstairs ru...

Re: Calcium Grains in a Tropical Winter

Alfred, Alexandra. How do you find the focus on your C11s?

I'm going to try collimating, focusing, putting a proper focuser on the back, refocusing and then imaging. I hate the native SCT focus I have to say.
