EM-11 & EM-200 How big are they?

Posted By Rob Mackie

Hans
It's been a while since I owned a G11, but I'd say that the EM200 is roughly comparable in size,perhaps a bit lighter. I find it easier to move about than the G11 because the GEM head can be quickly removed from the tripod. Regarding capacity, the EM200 will easily handle the M250 and FSQ. I use heavy imaging equipment atop my EM 200 and it handles everything without any problems whatsoever. Quality wise, go with the EM200. It is a superb mount and a significant step up from the G11. If you're strictly a visual observer, either mount will keep you happy. If you're sure you'll be using an M250, go with the EM200 rather than the EM-11. You'll appreciate the extra capacity of the EM200.

FSQ 106 ED Pictures and Preliminary Observations

Posted By Rob Mackie

I just spoke to Art at Texas Nautical. He tells me I need a 25mm spacer between the ota and prime focus adapter (see my comment #3 and #6). He's sending it gratis and tells me this should eliminate vignetting, which is due to my using the 2" visual back between camera and prime focus adapter. I'll let you know how it works.

Monkey Head in Narrowband Color

While checking out this image on your site, I took the opportunity to view many other images. You've got a nice processing touch, not at all heavy-handed, that produces consistently excellent results. I note than your exposures are longer than what I'm accustomed to. I typically do 15 or sometimes 20 minute Ha sub-exposures. Yours are longer and the total exposure time is also considerably more than my usual 2 - 3 hours. Are you imaging from a dark site, and is your mount located in an observatory? Aside from Ha, I don't do much narrow band imaging but that could change, especially after viewing your results.

Excellent image! I like it very much and want to take a shot at it myself.
