I hacked two macrorails (one manual and precise and the other motorized but wobbly) together to make my Frankenstein-rail. Haven't had lots of time over the past few weeks due to a home improvement project that needed finsishing (cabinet to install a large Bosch combi steam/microwave/air/grill oven at eyelevel in the kitchen) but here is one of my first tests of the rail as it stands now.

I replaced double-sided tape and tiewraps with two-component epoxy, got a 220V adapter for my PentaxKP to avoid having to change batteries constantly because of excessive liveview usage and a longer cable so I can use the controller without inducing vibrations.

Shot on a Pentax KP with an Irix 150mm/f2.8 at an aperture of f5.6 and shutterspeed of 1/180th. I used a flash at 1/4th power manual setting through a Sto-Fen diffuser at 45 degrees and I let the whole setup become vibration-free between shots with a 6-second pause between exposures (also helped the flash keep up).

I did shoot raw+ but found the jpegs perfectly acceptable for stacking so I ended up using those. Post processing of the end-result output from Zerene (16-bit tiff) was in Digikam's built-in editor and final sharpening and NR in NeatImage. Click to see a larger image in Dpreview Gallery.
