It's Showing its Age...



Yup...the 10D is 4½ years old now...and it's showing its age.

Just two days ago, I tried taking a long exposure photo of the lightning (see previous post) storm and the number of hot pixels that popped up are definitely more than when I first bought the camera.



I guess it's kinda protesting against the abuse that it's gone through. I suppose once I save enough for the new 40D. At least it's got "Liveview" which should help in getting a more accurate focus while shooting either prime focus or through eyepiece projection.



Orion's 120mm ST OTA is a 600mm f/5 and is going for under 1K at Astro, but after reading about it, I'm beginning to wonder if a shorter but faster 600mm is a good alternative to my current 1000mm f/11 mirror...

Or should I get a NexStar??? The Orion accepts 2" eyepieces which is a BIG bonus cause I wear eyeglasses...

The difference between the new generation C90 (M's Scope) compared to my old C90 is quite obvious. The new C90 is a 1200mm f/13.3 which appears very dark even though the magnification is better...

Maybe I should continue with the C90 first because it's a pretty decent all-rounder and M's already got the monster NexStar 8SE...

Argh...decisions decisions...
