  1. I'm betting (cautiously) on star movement. 

     

    In all but the worlds cheapest tripods Mirror vibration self damps in MUCH less than 10sec. It is an issue with mid-length exposures (1/60-1/4sec), with long lenses or macro where the "perfect storm" of vibration amplification due to long lens length/high magnification *and* a lack of spare time to fill in with stable image (its not an issue in a 2sec macro shot, for example) fuxors your shit good - but mostly mirror shake is just something people like to talk about as the reason their handheld photos come out blurry.

     

    Anyways, in the case of your photo - With such an even exposure across the length of the star trails, I assume it is mostly the motion of the earth. If it was mirror shake, you would see a little motion, and an overexposed spot where the camera finally settled. You got none of that. 

     

    You could shoot a 2, 5, 10, and 30second exposure, and see if the trails are proportionally long. 

  2. Anything with a 5-pin DIN plug is balanced from the cartridge, that I have seen. It's easy to rewire if it's not.

     

    I could not be bothered to quote PretentiousFood...

     

    I'm not totally convinced of the benefits of a balanced phono stage. 

    Balanced inputs, so that you get noise rejection for the cartridge level signal, absolutely. Balanced RIAA? SOOOOOOOOOO much work for no benefit. 

     

    Balanced inputs. Convert to SE (transformer or op-amp based to get noise rejection) do RIAA & voltage gain single ended. Do whatever you gotta do for outputs (transformer or op amp phase splitter).

  3. I'm thinking a 24mm f2.8D but have read mixed reviews.

     

    I love my 24F2.8 AIS. The prophet Ken Rockwell (and yes I'm joking about the prophet thing) assures us that the optics are the same. 

     

    That being said, I would decide on a FOV~=focal length, and go from there. Its not *really* fair to compare such widely dis-similar focal lengths. 

     

    Or since this is head-case, just buy them all. 

     

    Because 24mm.

  4. Steer far far far away from any TT with automatic anything. 

     

    Adjustable VTA is nice, but also not :P 

     

    I think the audiophile community makes MUCH more of VTA than is necessary because a modern tonearm needs to be designed to be put on who-knows-what TT with who-knows-what height from the plinth to the platter. TT's designed to "just work out of the box" (by engineers {who got payed to do that}) can easily get VTA to within a few MM for any cartridge with a fixed tonearm.

  5. SA5K are also very placement-sensitive*. It sounds weird, but they might just fit your head better than other people. 

     

    That being said, I can never reallllly get their treble down to what I consider flat (HD800ish).

     

    * Most headphones are, actually.

  6. Craigslist - mid 80's to early 90's high quality turntable.

     

    Integrated receiver (1970-mid 90's?) with phono input. Will probably have a niceish radio tuner and probably a passable speaker amp if you shop carefully. 

     

    New cartridge, or at the very least a new stylus if the TT comes with something niceish. 

    Maybe a record and stylus brush to help with the dust bunnies. 

     

    There is no reason to spend more than $200 all things told, and you can often do MUCH less if you are careful, patient, or already have some of the parts. 

  7. I have a Fortis. 

    I like it a lot.

    Edit: Please excuse the overall lack of quality of this picture. I took it before I figured out how to edit photos.
