Can't beat that price for a 6" scope with a 2" focuser.

well my SW 130/615 was $60,

and it's almost parabolic...

What a great price, hard to beat $60 for a real telescope. That is 50 times less expensive than a 130mm refractor, is it 50 times less useful? lol

Wow! One nice thing about a scope this size: you can even just put it in your lap and scan the skies with a wide-field eyepiece. A friend has one of the ES MakNewts mounted as a ‘finder’ on his 22-inch Dob.

If I didn’t already have my ATM 6” F/5 with a moonlight focuser, I’d order one of these. My scope was built around an old commercial mirror set that was not very good. OWL re-figured it for me for a reasonable price with a very short turn-around. However, I bet I have a lot more than $190 invested.

Is the 6 X 30 straight through finder correct image or mirror image?

Thanks.

I put it up to my tv genesis that it's next. looking at saturn it was only a little softer. I was realy suprised at the magification it took.

so $60 compared to tv genesis could go for $950 but when original how much was it?

Not a correct image but an upside-down image, not sure if it is mirror image but I never considered using it anyways.

The 6x30 finder looks like the same that is supplied on many Celestron, Orion and SkyWatcher telescopes. It produces an inverted image, same orientation as in a refractor without the diagonal or in a Newt. The image is just turned 180 degrees.

Well, I ordered one of these 6" OTA's this past Saturday night. I've been looking for a 6" f/5 Newt with a 2" focuser for a long time. I want to maximize the aperture and ease of portability and minimize the weight and cool-down time for a grab-n-go scope. I define grab-n-go as one trip out the door, telescope on mount. Anything else is not really grab-n-go.

I also like the image orientation in a Newt: inverted. Ideally, I'd want the natural orientation, but that is difficult to accomplish optimally except for binoculars. I don't like a reversed image as in a refractor+diagonal, Mak or SCT.

The fact that the Woodland Hills vendor verified that these XLT 150's are shipping with a 2" Crayford closed the deal for me.

Looks like I might be selling my 130mm f/5 Newt soon.

Maybe I'll do a three-way shootout among my 6" f/5 Newt, 6" f/12 Mak and 6" f/15 SCT. It's difficult to justify keeping all three now.

Get this from the ad patter for the Omni XLT 150:

Quote:

Using aspheric shaping technology in conjunction with hand-figuring the optics, the Omni XLT presents an image with virtually no spherical abberation.

A fancy-shmancy way of saying the primary is parabolic.

Is anyone or has anyone use this scope to image with and if so, How well did it do?

Several Danish imagers use 6" f/5 dobs and they do very well indeed. You need a coma corrector, of course, like for any other f/5 newtonian.

This image, for example: http://www.astronomibladet.dk/images/stories/aktivastronomi/m81-m82.ed1.jpg

is taken with a Sky-Watcher Explorer 150 on an EQ-3 mount with a Canon EOS500D, by danish amateur Henrik Rosenørn. The Explorer 150 is virtually identical to the Celestron Omni XLT 150.

Clear skies!

Oh, that's tempting. I berate myself for selling my Omni 150 for some pittance a few years ago, and I'd be happy to have one back.

Joe, I enjoyed reading your excellent review of the Omni XLT 150 (old focuser version) while I waited for mine to arrive in the mail. The comparison versus the Astro-Physics 155 f/9 EDT was enlightening. Also, you're right about that faux-Pentax freebie EP that comes with the scope--it's not too shabby!

Orion discontinued their 6in imaging newt.
It had 2in crayford with fine focuser and built-in extension tube.

Try using WO binoviewers with the newt.
Nice comet scanner.

I'm trying really hard to convince myself that I don't need this scope.

I also noticed that the WH website's description of the scope has not been revised yet.

Interesting! This looks like it would be a great grab and go scope. I don't have any mount for it.

What would be a good but simple mount for this scope? Something like the mount in the op photo? What is that one?
