I find LED spotlights are a good option (bright, low heat, if a bit expensive for a bulb) generally in a desklamp mounting.
I often end up using a LED torch though as it saves finding an extra power point, and is more easily redirected.

I see no reason why polarisers shouldn't work perfectly well at night, but they won'y increase the contrast of your skies.
They should be able to reduce reflections on a surface so you can see through better, but I can see potential problems with finding suitable subjects to try that at night...
Perhaps a moonlit seascape might be suitable, but as Ken infers the exposures will become rather long.

Great so for my 1000-4000mm telescope that works out at 3.125km at the wide end (which is f16) to 12.5km zoomed in (f64) no wonder focusing it has been a pain!

Can you explain how the calculated hyperfocal distance of 4900mm (4.9m) has you setting the focus to 2.5m ?

Yes, any pentax Digital camera will work with all Pentax lenses.

You don't mention which series your old lenses are but from the camera model I'd guess F or FA lenses which are fully compatable.
Older K & M series lenses do not give you electronic control of the aperture but can still be used with 'green button' metering.
Antique M42 screw lenses need an adapter, but otherwise work like the M series.

Edit Drat,Graham beat me to it.

I'd don't think either of these are free. If you don't already have them it might be possible to develop them but it would not be at all easy

Personally I don't want to limit myself to an individual style, I think the subjects & fields of photography I play with are too varied for this to be possible.

In response to the Original post, there is already a private way to lend support if required.

This remains between you and the receiver and avoids anyone joining the forum for a nose...

My thought are with Bernard, and I hope he gets this outrageous situation suitably cleared up, but I fail to see how going over it continuously will do anything to help him get it sorted - and could just make it more awkward.

I've got one double axis one & now a disc type one (which stays on the carera as a hot shoe cover).

I don't use either for everyday shots, but for IR work, where I can't see ANYTHING (other than perhaps the sun) looking through the viewfinder, they're easily worth the cost.

Using the extreme ND filters/ nighttime seascapes etc. are typically similar.

Even without low light working, the K100d viewfinder is rather small & dark not good for judging horizontals. My old ME/MX/Zenit etc are much better. I'm guessing Smeggypants has a pentaprism camera not a penta mirror one


Almost forgot the other extras. I've got about 2/3s somewhere or other, but the only one I'd consider a MUST HAVE is the blower. Other potentially useful budget toys include;
a welding filter Shade 8 is best) for ultra long exposures (with custom WB)
Tabletop tripod
An adjustable lens hood (Black foam sheet & velcro) Folds flat yet fitts multiple lenses

There are RF remotes to operate the flash (which unsurprisingly work via the hot shoe). I've not heard of any that control the camera, though it shouldn't be too difficult to make one that plugs into the remote socket (Instructables probably has a design).
I suppose it would be possible to design an RF receiver that had an IR output - a hot shoe mount might make sense for that.
Was the article you read written before the K-x came out (or perhaps just based on old information)?

I've had several sets too, most have been excellent but one set seems to loose power excessively I think it may just be a single dodgy battery (I do remember my charger reporting one as faulty which then seemed OK after re-seating it)
Perhaps the reviewers had a similar temperamental battery...

For the price I'm convinced they're worth getting even with the occasional dodgy one (The set still works fine just runs down quicker etc)

Still looks rather low in pixel count but at the rate those go up by it woun't be long till it beats my left one - even without the zoom.
Hopefully I'm getting mine upgraded this year - the MK2 eyeball is sure to be an improvement
