Piggy Back

How often does an amateur astronomer get to use a 2.3 meter telescope for astrophotography? And even better - use it only to piggy-back their cameras on the massive 6 ton mount to use as a tracking platform. Well - here are a few shots taken with such a setup.



NGC 2239 through a Canon EOS 5D and a 400mm lens. This is a sum of 25 5 minute exposures at F/4.0. Processed with ImagePlus and PSCS3.



M33 shot through a 6" F/9 APO refractor with 0.63 Focal Reducer onto a Canon EOS 1D MKIIN. 32 4 minute exposures at F/5.6 processed with ImagePlus and PSCS3.



IC434 shot through a 6" F/9 APO refractor with 0.63 Focal Reducer onto a Canon EOS 1D MKIIN. 35 5 minute exposures at F/5.6 processed with ImagePlus and PSCS3.

Very nice images, Dave. I really like the Horsehead region!

Are you using the Canon software to control the exposure length Dave?

I've been tempted to use the MLS 60" and my piggy back mount, but we don't have enough engineering time during dark time!

I love the photos, Dave. They could all hang in my living room anytime. Wonderful work....Sallyann
