Sunset Aurora 26th October

So we arrived in Iceland a few hours ago, clear skies and cold! We're stopping about an hour out of Reykjavik in the sticks, with little light pollution. The aurora was visible as soon as it started going dark. 98 frames, 20" sec exposure iso 800, 10mm f4. https://live.staticflickr.com/65535/4896441...

Don't forget to de-aluminise the secondary mirror!
Depends how much light you want coming through 😉

Re: Interference eliminator and tilt adjuster

The daystar interference eliminator is my personal favourite Pedro. I use mine on the ep end to connect it and the camera to the quark.

Re: Dark filament in 3-D through C8 telescope.

That's a superb image! Do you use the same barlow lens with your Ha images as you use with the CaK images with the C11 Valery?

It's quiet indeed. I'm hoping it picks up once we get to the other side of winter. Nice disk John, what does the Mg look like?

Re: Lunt monster

A 100mm internal etalon with 300mm objective would mean that the sweet spot would be smaller than that of PST. You could see the whole full disk with this but not all of it would be on band.

Saturday Sunshine 19th October

Hi Everyone. A last minute change of plan to the weekend meant I had time for some solar observing, a rare thing for me as we head towards the winter season. Took some time for the back edge of the weather front to finally budge, where I was rewarded with lovely transparent skies, but the seeing was...
