Quote:From what I've read the EQ-M1 drive is the one to get, not the AstroTrack drive. The EQ-M1 is supposed to be more accurate with better electronics.
Quote:But seriously guys, the thing will fit in a suitcase or a backpack, runs on a couple of D-cell batteries, and can be set up and ready to go in a couple of minutes. Plus it's cheap! To me, it sounds ideal for traveling to dark sky sites while on vacation or stepping outside in the backyard for some quick imaging. It could be fun.
Quote:Rather than drift aligning, simply mounting a small scope and putting the mount in 'home' position (counterweight shaft down and scope parallel to RA axis) may be sufficient to get a decent polar alignment by putting Polaris in the center of the fov (if you can see it).
Quote: When I bought mine I never thought I'd be using a lens longer than around 50mm with it.
Quote:I think I could justify buying a prime 50mm f/1.4 to use with this setup. Patrick
Quote: So, actually there is no point in paying 3.6x more for the 50/1.4 for astro, except for build quality, etc.
Quote: How did you attach the mount to the tripod is look like a pvc pipe of sorts....Also what make of tripod is that?
Quote:Does that mount have a vixen dovetail receptacle or something else it's hard to make out
Quote: So how did you do the polar Patrick...
Quote: Quote: So, actually there is no point in paying 3.6x more for the 50/1.4 for astro, except for build quality, etc. I took a look at both of them at the local camera store. The build quality is definitely better with the 1.4, ie...metal bayonet vs plastic, plus the 1.4 has USM autofocus, etc. It's kind of a toss up, but I'm still leaning towards the 1.4 based more on that then the aperture. I have so much sky glow I could be shooting at f/8 and still be fine on tracking. Re the f/1.2, it's out of my league.What are your thoughts on the actual image quality differences between the f/1.4 and the f/1.8 such as edge of field quality, etc. Do you know if Canon uses the same type of glass in both lenses? The local camera dealer said the f/1.4 had better image quality, for what that's worth. What do you think?Patrick
