Whilst waiting for the kids to go to sleep I get the chance to wish you all the very best for Christmas!

I believe the originals are now freely in the public domain so here's a couple:

http://flic.kr/p/94brRY

Both have distinct colour casts from the old slides, which I've only partially removed in PP.
As they're not really my own work I'll be removing them from flickr in a week or so, & to err on the side of caution I think it best to only post links.

I recently copied (photographed to digital) some ancient slides of my Dad's. Amongst his collection were some old NASA slides (Gemini/Mercury era) - If I photographed those, they'd fit your title nicely... - But I guess that's cheating.

I've had some tele-converters where the aperture lever on the TC tended to slip peat the one on the lens, jamming the two together. It was possible to turn the bayonet about half way but not separate them.
I eventually found a slight sideways pressure on the aperture lever slipped them back past each other and allowed them to undo. Ten+ years later I found them & used them again having completely forgotten the cure.
Much cursing ensued, but at least this time after I finally got then apart I took the chance to cure the fault (a slightly bent lever on the TC)

If the bag was sold as a buy it now it falls under the distance selling regulations. In which case, unless the returns information in the listing says otherwise return postage must be paid by the seller. (Saying No returns is not legally allowed for BIN or relevant for goods not as described)
In E-Bays safety centre I find this 'In general, the seller is obliged to pay for the return postage & packaging unless they have specifically provided, within their returns policy, that they require the buyer to pay for it.' Which can apparently apply even if you just change your mind

I would add to SmutjeUK's advice that return postage costs should be paid by the seller if it's not as described.

I've tried out a generic e-bay power supply (switched mode 6V, 7.5A max) with my K100 and it seems to work OK (Apparently the Pentax one for the K100 is 6.5V & 3.5A).

I'm also intending to make up an external battery box to hold 4 D size duracells, for use away from power points. I might get it done next year...

No 5 looks like salt rather than sugar, but there are thousands of compounds it could be if not restricted to everyday household items.

I'd agree with Peter that after 'batteries, spare card & practice' a CPL is the most useful (It controls reflections & can help pick out clouds etc.)

I find graduated filters generally don't fit horizons so the software approach works better. Non graduated ND filters can let you extend exposure times - but generally require tripod use because of that! For extreme applications (e.g. removing pedestrians from street scenes) welding glass can work perfectly and is much cheaper than equivalent photographic filters (ND10 equivalent £2 instead of >£50)

The effects of most filters can now be easily reproduced via software, so the requirement for them is MUCH less than with film. However this can mean that some are sold secondhand for very little - allowing you to play with ones that seem interesting.

To me the best accessory for general photography is a Tripod (strongly recommended for low light, macro & even landscape work), beyond that it starts to depend on the types of Photography that interest you most. Playing with your new camera will help you decide that...

It always amazes me that some people try to turn a good steak into a piece of leather before eating it.
Blue is perfect, but if its a bad cut you might want to overcook it to medium rare.
Unfortunately some restaurant's idea of medium rare, is well beyond medium.

Personally I'd avoid the tinnies too most of the time, the metal taints the flavor of any decent beer. Stubbies are better - and would probably be my choice in hotter climes - but most of the time I prefer a darker beer. (Porter, mild, winter ale, or Trappist dubble...)

Snows nearly all gone at home now & I've got my car back (undamaged). I think a nice beer (or two) is called for to celebrate - the Grimbergen will do nicely
