Aberdeen may get to see them but according to Gedds they won't come much further south.
Note that the shaded areas refer to the locations where the aurora will be overhead. Because the auroral forms are more than 80 km (55 miles) above the earth, you may see them from as far as 400 km (250 miles) away

Pentax 16-45 F4
Sigma 24-70 F2.8
I now have a Tamron 28-200 as a walkabout, small light and decent IQ, cost £50

Different crop, rotation, tweaked exposure, and unsharp mask.

wasn't that sharp and produced terrible shots so
Not sure about the elephant shot, when I look at the original it does look a bit sharper.

the alternative to a big lens is smaller lens and stealth

The lens has its critics but easily available off ebay for circa £220;



All handheld.
With some PS work they could look quite impressive.
IMHO If you put ANY teleconvertor on your 55-300 you will lose so much light and gain so much shake at the long end it will be a waste of time, and money. Remember your SR on the converted zoom will not work properly unless you change the fl every time you move the zoom.
Teleconvertors only work in the field on large aperture primes, or expensive large (f4 or larger) aperture zooms. If you cannot afford one of the big Sigma zooms I honestly believe you should look at a cheaper long range prime. Do not waste your cash on teleconvertors for small aperture zooms, I speak from experience over the last 2 years.

Sometimes the setting means much more.
Well done.
