Our biggest source of light polution is Teeside about 40 miles away. If you know where to look Carlisle (30 miles) produces a little patch of orange on the horizon. Tyneside p

Or a bit a of junk. Around a couple of hours after sunset the sky is crawling with visible satellites. Couple of hours as by that time it's dark enough on the surface but the satellies are still in full sun.

There is an Android app "Space Junk" that lists and plots a lot if not all the visible bits of junk/satelites that is hurtling around up there.

Wouldn't rule it out but the ISS is very bright, something that attracts your attention. The first time I saw MIR it was a "WTF is that, aliens?" moment, quite fast, very bright (think venus bright). Came in and checked the Heavens Above web site.

Ordinary satellites look like medium brightness stars but then you notice it moving.

For the dog/cat/bins it'll be ample, added advantge is that the shadows or areas outside it's reach are not pitch black hiding a whole tribe of tea leaves.

I saw three satellites, and no Perseids. /She/ is really p***d off by the barn owl that went past me at head height 10ft away. I've never seen one so close!

Been there too often.

Both tasks should be as easy as each other at 30ft on a ladder:-)

I'll work up to 20ft on a ladder at a push, but anything after 15ft I find uncomfortable.

I used to apply grease to the screw before installing

I'm still using some 40 year old copaslip. I will run out one day or lose it in the shed I suppose.
