Description

Well I put together this machine to use my EF400 lens and make Long exposure astro photos. Decided it was time for the big test tonight. Beautiful night. Hardly a twinkle in the stars. A front moved through the past few days. Dumped 6+ inches of much needed rain and cleared out the sky nicely. Going to be that way for 4 more days too Finding the fuzzies is even harder with the EF400. I'll be glad when the Argo gets here and my DIY encoder works as planned. Anyways this is the NAN at 400mm actually 640mm with the crop factor of the 7D. Saving up for a 1.5x teleconvertor. Don't want to go to 2x the f number is awfully high at 2x. That will give me 1000mm of FL . 640 impressed me having done the same object with the 200 the other night Filled the frame. I'm sure there is more to be pulled out of the data. Just picked up Neil's Astro Tool Actions and a couple of very nice tutorials so I have something to go through them with.
