Best piggyback shot without a drive

Hello, I was just curious if anyone else out there has ever done any piggyback astrophotography without a drive on their equatorial mount. I can't afford a drive, so instead I do it manually.

I took this 20 minute exposure of Orion by continually adjusting the scope every five seconds or so using the manual slow motion controls. I used my 8" SCT as a guide scope and centred on Alnilam, then brought it out of focus so it was easier to determine drift, both in RA and Dec (I didn't properly polar align my scope either).

Just curious if anyone else out there has any piggyback shots from such a painstaking method?

That's a great job.

What film did you use? It seems to have good red sensitivity.
