Problem with fixed aperture f8.0 on 500 mm mirror objektiv.
How can I change exposure time and get the camera to change ISO according to exposure time.
The only way seems to be to manually change ISO.
Anyone got another way to do it?
M or Tv does not give the possibility to change exposure time with the front or back wheel.
IIRC TAV mode with auto ISO should work OK for getting the settings you want.

I've used it on the odd shot but I can't really see what it is supposed to do? Can someone with more knowledge of hdr expand on it a bit?
In many cases simply preventing the highlights from blowing out, then pulling up the shadow detail will work just fine. There is a bit more control to the HDR process if doing it in post, but all too often that's used to spoil the images!

I don't normal use my widest option in narrow streets, the 360° FOV could be effective but it's a bit of a pain to set up. The 10-17 does get used as have options with a 300mm+ equivalence.

I've never been to Cadwell, but I'd heard of it's little jump, shown to good effect here.

I'd heard the milky way was best shot from the far side of the world. where it's center is visible in the dark hours. Obviously I shouldn't give up trying just because of that.
We certainly don't such dramatic foreground subjects along the east coast, but a view of the milky way should at least be possible

Agreed about quick release tripod mounts. Seems each manufacturer to their own! I suppose if one has a broken tripod, but still have the QR mount it might be worth getting that tripod. Not much point otherwise. I wonder where all the old QR mounts go?!

I see a lot of tripods, but by far the majority are quick-mount ones, but without the mount section. Having had to replace the mount on my own Slik tripod, I know what a pain they are to source.
The 52BB was a good buy - I don't know what the lens is like, but if that's an M42 to PK adapter, that's worth a pound any time. I've bought a few M42 lenses, but I've stopped doing now, unless I see something really special.
The adapter was an Adaptall2 to PK which I've never seen advertised at under £4 (e-bay currently have them from $16 to $40, or simpler third party versions around $. So yes easily worth the money, especially when the lens has a rather good reputation.

Has Rocky upped his game now?
I haven't used him since his Ebay days and he was an absolute nightmare then. I was one of the very few that got a refund on some very imaginatively described equipment and that was only because I lived so close and told him I would collect in person if I didn't receive it soon.
I've used him around half a dozen times, and twice had something small missing from the order. Last time neither of the items ordered arrived - when chased he sent a couple of e-mails saying he was out of the office & would investigate on his return. Since then he hasn't bothered replying.
I won't use him again.
I used to mention him when people at the workshop are after cheap bits, but I won't do that anymore either.
