macholtz and pleiades
Skies finally cooperated on Friday night. Here's my very first attempt
at astrophotography with the canon digital rebel. It's amazing how easy this thing is to use. https://webspace.utexas.edu/hillcp1/...%2003 30z.jpg This is a combination of 4 30 second exposures at ISO400, through a vintage pentax smc takumar screwmount 200mm telephoto lens @ f/4, piggybacked on a c8. The image has been washed and tweaked a bit with photoshop. Not too shaby for a first try. Can't quite get the magenta skyglow out yet, but I'm working on it. I'm not recording much tail at all. Here's a reverse grayscale of the comet itself before processing (ie only the 4 tiffs combined and then saved as a jpeg after cropping): https://webspace.utexas.edu/hillcp1/...0greyscale.jpg Chris |

Chris,
Fantastic image, especially if it's your first try with the Rebel! Did you let the Rebel do the dark frame subtraction or did you do it yourself in Photoshop? I'm trying similar with my Minolta 7Hi but the skies here in Maryland have been overcast almost non-stop. I tried a piggy back session last night in between clouds with not so good results. Andy |

Gotta try the stacking. But first gotta improve my drift alignment technique. My stars look like little dumbells. Right after I shot the set of macholtz pictures, I tried for a set of Orion's belt and the nebula, and these were not as good, some with dumbell shaped blobs instead of stars. I'm thinking that mirror shake may be a problem, so I'll try a black hat next time (if it ever clears again). I think I'll eventually try the firmware hack to get mirror lock-up, but don't want to void the warranty on this camera yet when it's only a week out of the box (smile). 'luck - Chris Thanks for sharing. Nice work.
