telescope on an slr?

hello . dont really know where to post this but here it goes.
has anyone used a telescope to take picture of the moon and such long distance subject, if so how good is the IQ?
any recomendations as im looking ofr that kind of set up soon.
thnx for the responses.

This would probably get a better response in the Talk About Astronomy section...

Yes, but only on film, I haven't done any digital astrophotography. Of course the IQ is good, but that depends on the optics of the scope itself.

I've tried astrophotography with my 40D + Meade ETX90. The problem is the digital bodies are much heavier than their film counterparts and need more support. Otherwize its the same.

One difference is that you will want (if you don't already have) a remote shutter timer.

Keep in mind most telescopes were not made for taking pix through.

Most *bargain* telescopes were not made for astrophotography. My old '6 Meade Newtonian was designed specifically for deep space, wide-field astrophotography. I've managed a few good shots through it over the years, but my skills don't match its capabilities. If your telescope was bought at Wal Mart, Hobby Lobby or through the Sears Wishbook (I'm dating myself, I know) then it's not going to work well. Higher quality Meade, Celestron, Orion and other brands with stable mounts and good tracking systems can give excellent results. The added weight of digital SLRs isn't an issue, as T-mount adapters can handle it and the counterweight on the telescopes GEM adjusts easily for compensation.

Astrographs are telescopes designed specifically for use with a camera--they're not intended to be looked through, visually.

Many serious astrophotographers mount their cameras and control the shooting remotely via a computer. Digital photography has opened up astrophotography for hobbyists in ways that wasn't practical with 35mm film. Check the astrophotography forums here, and also over at Cloudy Nights for lots more information.

I took this Moon photo with my 50D hooked up to my Meade ETX 125. But in that case I think we're talking about a DSLR on a telescope and not the other way around (even if the the etx125 is fairly compact)

Great stuff here

That is a beautiful moon shot - You can even see the colour coming through - Excellent!

Thanks. I'd recommend checking the astronomy section of the forum for much more info on this.

My ETX 90 starts to sag when I attached my 40D to it... even barebones (i.e. no grip) the weight was a bit much for the ETX 90's motor... it kept getting off alignment.

I actually disassembled the built in base on my ETX90, and attached an arca-swiss plate directly to the bottom of the telescope, so i can mount it straight on my tripod. It works a lot better, if still not perfect since the VF gets very dark and is hard to focus.

Check out the astro section.

As for me, I would rather shoot with the Takahashi FSQ106N (astrograph, but excellent visually also) than the 500/4L EF IS due to the optical quality. Both are in the 500mm range, but are worlds apart, optically speaking.

There are good telescopes, and there are no so good ones. Same with lenses. But even the best commercially made camera lens in the 500mm class focal length can't really compare with the Tak in terms of contrast and color correction.

Takahashi scopes are prime glass. I'm not surprised it out-performs even an L, although I'll bet the minimal focusing distance is a bit longer. Also, you're going to pay a premium on the Tak over the L.

About 18 months ago, I ordered my dream scope, the Meade LX75 SN10-AT. That's a 10" Schmidt-Newtonian, and the kind of scope I've been dreaming about for 30 years. Alas, they were backordered, and by the time one came available, my carefully hoarded cash had been spent on car repairs and other mundane necessities. It's probably for the best, though. To get the kind of quality astrophotography I wanted, I'd have had to upgrade the mount to an Orion Atlas, replace the focuser, and a host of other little tweaks that would've ended up costing more than the original scope purchase. But hey, someday...

Have you tried the same shot with your 7D? Bet there would be even more detail!
