I know some of these zoom lenses move, especially when pointing up high where Antares is at the moment. You were smart enough to tape it to prevent this, well done. I'll have to give this region a go myself, you've inspired me to dig out my zoom lens.

Haha, was a bit cool that night, funny enough the stubby holder now has a dual purpose! It hugs the lens acting as a dew cover while taking the chill out of the metal. Will have to take flats next time to remove vignetting though. I'm tipping another challenge in itself. But it did its job keeping the dew off the filters covering the lens.
I used a Canon EF 90-300mm F4.5-5.6. Its versatile for wide angle and close ups like this image. I found that the focuser slides under its own weight when pointing to the zenith, hence taping it to the lens body. Its a bit rough and ready but does the trick. I also had to remove an artifact that it produced (some reflection spot offset from the bright Antares), maybe a result of using filters in front of the lens perhaps?
I was keen to have a go at Rho after seeing an awesome post of this subject going back recently. Its a lovely area of the sky.
Good luck Mickoid.
