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

Nice collection of images Eric!

Nice images Pedro! That prom looks great.

An excellent set of images there Marty!

Good disks Eric!

Nice sun pics Martin. Good looking setup too!

What 2x barlow are you using for this image Valery?

These came out well John

Came out well Alfred!

Great shots Martin. Looks nice and warm where you are.

A super collection of images Eric!

Top shots Brian! 104 is impressive.

Thanks everyone for the kind words! Much appreciated.

Sounds a plan

What barlow is it Valery?

No frost here yet either, but must be close...

Thanks guys!

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...
