I want to mount my Meade 10" OTA on an equatorial
      #4566442 - 05/06/11 11:38 PM

Want to keep it under a grand.
The GG5 has a weight capacity of 38 lbs. The OTA is 28 lbs.
I plan on only doing astro work with my canon dslr.
Is this mount a good one for the price?

That's a visual capacity. You won't be getting good pictures at 2500mm focal length on a CG5. Even with a focal reducer it is a stretch.

Look for a used Atlas even that is borderline. $1000 won't buy you much quality at the payload you need to carry.

yep. wrong scope (too long focal length) and not enough mount to start AP with... will be massive frustration...

You will need a Losmandy G11, Celestron CGE(used) or Celestron CGEM-DX at a minimum.

All those are nice mounts, but a Meade 10 will ride _quite_ nicely on an Atlas EQ-6, too.

Oh yeah it'll ride ok but imaging with that mount and tube will be a challenge. If he said he were visual only I'd recommend the atlas without hesitation. Unfortunately he wants his cake and to eat it too.

It's more than possible to image with this OTA on an Atlas. Yes, it would be easier with a larger mount...but substantially easier in this case would need to be the next step up from a G11...Titan, AP, etc.

Frankly, I don't think a 10-inch Meade is a very good imaging solution for most folks. It is heavy, and the major "gain" over a C8 is a narrower field...which ain't much of a gain.

The Meade 10" ACF is an excellent choice for imaging CAT man. Nice Wide Field also.

NOT for a noob to AP, it isn't...

between that focal length (can you say spend at least $5 k on a mount)? and it's sheer weight (can you say spend at least $3k on a mount for visual?), it is NOT a scope for AP for the faint of heart... and a CG5?...



fuggedaboudit

not gonna happen...

Meade 10'ers are nice scopes, but for AP, one has to know what one is getting into... they are heavy for their aperture...

The Meade 10" ACF is a good scope for AP, but its challenging and is not easy. I've had a long love-hate relationship with my LX200 and we've been on speaking terms only since its been sitting on a GEM. And even with that it still is a challenge.

For AP you'll need a mount that can handle the weight (28 lbs naked, and there's a whole mess of other stuff that goes on there too - camera, finder, rails, etc.). You'll also need to respect the focal length constraint.

I'd say you'd be at a disadvantage with a CG5, and should re-think that first.

Hmmm, for a smallish CCD a 10" is a big scope, but for a DSLR it should work fine. A CG5 is probably a tad light unless you're careful. I've been imaging with an LXD75 AR-6 and a DSI Pro III and this is a fairly heavy scope (about 28+ pounds fully loaded), but I wouldn't recomend it for a beginner.

Nice wide field, huh? It may have other strengths, but even reduced to f/6.3...Not So Much to that.

The field is awesome. Even reduced to 6.3.

I did put my old Meade 10" on my old Atlas and for visual it was fine if a little prone to vibrations when focusing making that job difficult.

Imaging was a whole different matter. To image, a guide scope is essential adding to the overall weight along with whatever camera+imaging accessories you use. In my case I very rapidly maxed out the mount.

If well balanced it will swing it around but I found that the amount of counterweight needed at the end of the bar caused some nasty vibrations that made imaging impossible and focusing was near impossible. In a nutshell, with all that weight, I never got a useable image.

After that experience I sold the M10 in favour of the much lighter C9.25.

I should also add that this change didn't solve all my problems. I've been trying to image for about 2 years now and only in the last 6 months do I feel like I'm getting a handle on things. This is largely due to the fact that I gave up my stubborn pursuit to image at long FL and resorted to my WO110 at 650mm. Guiding this on my EQ6 was a joy and I finally managed to get some images I would be happy for others to see (still not great but presentable). Only when I gave into this did I feel like I started to learn what I was doing. Before with long FL heavy scopes it was an exercise in frustration.

I now have a G11 that's awaiting first light so I'm hoping this will give me the extra pulling power I need to move beyond the WO.

I have found my intro to imaging with a CGEM and a light (13lbs) f/5 Schmidt-Newtonian challenging...I can only imagine the frustration of attempting to begin imaging with a heavy, "slow" tube riding on an even lighter mount...

How the heck can a 10-inch SCT have a wide field? My 8-inch is a 2000mm FL.
