NOTHING is more comfortable for visual use than an alt-az mode fork mount SCT.




I would think that an alt-az fork mounted SCT would have trouble with Dobson's Hole.

Yes, they certainly do; or rather, the observer does, due to eyepiece positioning.

Not sure about disposable, but my luck absolutely sucked last year with anything that had electronics in it. My Nexstar11gps, CG-5, and AVX, all crapped out on me. The 11, and 5 went out in June. The 11 was bought used the September before, and the 5 was only 6 months old. The 11 was not a cheap fix ($800, including shipping) and the 5 was warranty. The AVX died on its 5th use! They just swapped out the whole thing, due to ongoing issues with some boards I guess.
Not a good trend, but Celestron made better what they could, and I'm glad. If it was "disposable" I really don't think they would've been as quick to rectify everything as they were. So, some would see it opposite the way I do, and have given up. Others, like myself, see it as one of the risks with electronic equipment.
It may help that I was a Sonar Technician on submarines a long time ago. I learned that even toilets break when you least expect it. Luckily, it never broke on me. Lol

Another bubblehead? I think you are the second or third one I've found on this forum. ET2/SS here. SSBN 659 Gold Crew. On my boat, one guy earned the "Golden Crapper" award not once, but twice, the same night. Sometimes, even with toilets, it's operator error. Not me thank God...

Normally I agree with Rod (except when he discusses my former employer LOL).

I find a SCT on an equatorially mounted fork to be much more comfortable to use than when mounted alt-az. Easy to see the whole sky from a single standing observing position.




Yeah, it's all bluebirds, puppies, and daisies...till you get near the pole. Anywhere near the pole.

Lol. I always looked for bubbles. STS2/SS USS HAMMERHEAD, and Spadefish. Yep, a river rat too!

Well, I figure I'll just dive in, even though this is like my third post. In response to the OP, how would something like the Celestron CGEM Pro mount fit in there? I am in the market for a telescope, I have been for some time and the funds will finally be coming together sometime this year.

I keep debating which mount to get...the Celestron CGEM DX or the Celestron CGEM Pro. The DX is a nice mount, lot of people have it, no one really seems to complain about it. The CGEM Pro, however...it is the only thing on the market except maybe Meade's new mount that "looks" like am amazing feat of engineering.

But...does that matter? Is the CGEM Pro worth the extra price over the CGEM DX? Or is the DX more than capable, and something that could last for the next decade or two just as well as the Pro?

anything treated well will last a long time. Mechanics will fail, that's a reality. The classics we see are the ones which were well built had survived, but the ones that didn't will, you will hear the sounds of crickets.


Made in China is a subjective thing since there are high quality items made in china. If companies buy low end items from the factories...guess what? I know first hand of this.

I've always figured down the line if I get several good years of good use out of it before it craps out, just deforking it and putting it on a AVX or whatever they have at that time.

It'll die someday maybe but I'm ok with that, it's not like you have to throw the tube away.

My CPC925 lasted about 4 years before the Alt motor became intermittent. Eventually I removed the OTA and it lived on an Atlas mount. Sold both later when I bought a AP900GTO. I use the AP mount with refractors and an C11EdgeHD. The C11EdgeHD is a heck of a lot easier to manage than the upper assembly of my old CPC925. I do monthly volunteer public outreach with our Planetarium's CPC11 scopes so I still have the regular experience of lifting the upper motor/scope assembly onto the pier.

I sometimes use my C11EdgeHD on a DM6 mount. Pretty easy to setup but refractor's wider fields of view are better suited to non-tracking mounts.

I am currently using the CG5-ASGT mount with my C11. I find the setup to be quite stable and very enjoyable to use. In my light polluted neighborhood, I have no problems viewing the planets, but need to get to darker skies for DSO's. I am considering getting the CGEM mount which can handle the weight of my C11 plus all the accessories I like to use. I will keep the CG5-ASGT for my NExstar 8SE to use in GEM mode and not alt-az mode, but will keep the Nexstar base for use in the winter when it gets too cold outside to fiddle with aligning a GEM when my fingers freeze long before the corrector plate does.

In Astronomy, "deforked" sounds like such a dirty word. I don't expect my CPC 1100 electronics to last forever. If/when the electronics die, I will use it manually. Heck I use it manually a lot any way. By then I hope I'm pretty good at star hopping. This may sound like a dumb question, but if the gears mess up, can I still use my CPC manually?

I have a Meade 2080 that was made sometime in the mid 80's to early 90's and it's still going strong after all these years.. The mirror is as good today as it was in 2000 when I bought it from the second owner. It has standard coatings as far as I can tell. But the mirror is very very good. It beat out several 8" newts, a couple of 10" Dobs (remember this was 2000 - 2002), and a couple of other 8" SCTs in side by side comparisons. No one could figure out why it was that good optically. I guess I just got lucky.

The only reason I bought the Meade LS8 was the light weight. My back and knees took a real beating since 2004. A light weight scope is now a must for me.

The gears are not likely to "mess up," so don't worry about it. And if by "manually," you mean loosening the clutches and moving it by hand...the gears are not involved in that.

As far as the longevity of modern SCT's is concerned obviously the OP is concerned more about the mount, as we all know that SCT optical tubes will still be in use after decades of service.
If a 'Go To" mount gets you outside more often, then good for you. Personally I still prefer the thrill of the hunt.
I tried a "Go To" mount once, and I found myself looking at the hand controller more than the sky. After the hand controller died twice within the first 3 months, I got rid of the go to mount as I wanted a mount that I could use for 20 plus years with out any problems. I bought a standard issue G-11 and have been very happy.
Just like John Lennon once said...
'What ever gets you through the night"....

I have a few semi antiques, and they are still very good. The older one is a real early version, 2.23 i think, and I have no problems. I was able to tear it all apart, inspect everything, clean it and put it back how it was with only minor instructions. I noticed very little wear, and I can only think it did see plenty of use as it came from a school. If the 10" ever died I would resurrect it with Autostar upgrade, then make an alt\az chair-bed out of the rest of the guts, with appropriate motor, clutch and spindle diameter upgrades, of course. I was thinking 8" Meade F\6.3 Sct with 45* diagonal, or better yet straight through with some binos! And an adjustable motorized headrest, of course. Dream on, right? But seriously, it'd be totally rad and cheaper than any of the super cool-guy mounts out there.

I use my CPC manually quite a bit. Sometimes I get lost in what I want to do for the night and just go "hunting"
I also use it this way for gathering objects for lists and awards where GOTO isn't allowed.
