NEXSTAR11 GPS vs Meade LX200 10"GPS
Posted 21 June 2003 - 06:37 PM
OPTICS: I give to Celestron. Much sharper image then Meade.
Alignment: close but I give Meade this one. Celestron first
star is way off from finderscope, I even reset to factory setting to start all over again but same result.
Satelite GPS aquasition: Celestron! real quick!
Less Noise when slewing: Celestron again. Very quiet when slewing. My Meade sounds like a coffee grinder.
Focusing: Celestron! Very little image shifting when focusing. For the Meade I purchased the Peterson kit to correct the terrible shifting I was getting. That has reduced the shifting to 0. Meade take notice.
Targets: Meade - has the 140,00 plus targets in its database. But whether I will ever get to see them all in my life time is another story....maybe in my next life.....
mounting scope to tripod: Celestron. Easier than Meade but once again I had purchased the Peterson mount kit for the Meade. Now it too is a one shot, quick mount. without it, it is Celestron hands down.
I havent had that many clear skys on the east coast here with all the rain but hopefully this summer I can really give these two scopes a run for the money. The loser will be sold but so far I really like the NEXSTAR11. Less perks but less hassles. and lighter to handle. Meade is top heavy and with the handles on the lower part of the forks its like a wrestling match lifting/setting it up. Anyone else have their own opinions on these two scopes? Thats all I can give you now.....

Does your Meade have the UHTC? I think my Meade has great optics.
As to the mirror shift...I experienced the same with mine, but since I have started backing off the entire locking mechanism when I set up I no longer have that problem. I was wondering if many people experienced that problem but still had a little friction left on the knob. The manual just states to loosen the knob. I learned almost a year into ownership I needed to turn it until it did turn to the right anymore. Also I noticed that periodically moving the mirror to the front and back stops helped reduce the shift when focusing. I had read somewhere that the grease was not evenly distributed on the gear and this helped.

As far as alignment being off in the Celestron? You have to complete a GPS alignment then calibrate the compass and level. Once this is done the first (and second) star should easily be in the finderscope. If you reset to factory settings, it will have the magnetic deviation set for Torrance and the compass will be off.
As far as the Meade being noisy, keep in mind that it is slewing at a much higher speed. I have the 11GPS and am VERY happy with mine and agree with everything you said. Just keep in mind the calibration item above.

Several other things...As far as the 46,000 vs. 140,000 object data base this doesn't even count. Connect your scope to The Sky and you have access to 19,000,000 objects. Same with a lot of other planetarium programs. How many of Meades 140,000 objects are duplicates? Use hcAnywhere and you have the capability of wireless control over the scope and are able to plan custom 200 object tours with hcTour.

I couldn't agree more. A large percentage of the database is also filled with stars.
So my advice, don't get carried away by the size of the database....don't equate it to aperture

Guess you can add that to my USB, Firewire, Bluetooth etc. wish list. They won't push it until the department store scopes have those options.
Better yet, put all the objects on slides, the data base pulls up the slide and you can look for as long as you want. CloudyNights won't stop you, cold won't stop you and you won't have to slew or align! You could even view in daylight!
Time for my meds

Success! After resetting to factory, the GPS auto alignment was performed and calibration of compass done. I did detect a slight drift on the target after 30 minutes. It was still in the FOV but near the edge. Maybe I should re-calibrate again? Last night the sky was great! Looked at M13, M27, M5 all came in quite beautifully. Even saw a few meteors. The optics on the NEXSTAR11 were great. I had a nice quiet night of slewing.
Clear Dark Skys

You are right. I can (and will) purchase the programs for more targets and load it to lap top and run it to my scope. I had quite a few owners tell me to do this. And I am taking yours and all of the others advice to do so. I still have to purchase the hardcase for the Nexstar. I plan on doing CCD imaging so I have a long way to go. This rain we have been getting on the east coast is very discouraging. Hope the SST at Savoy MA is clear....
Reguard and clear dark skies to you

Anyone else have their own opinions on these two scopes?
I've had 'em both. I liked the quiet slews and smooth focuser of the Celestron. I also found it easier to load/unload and setup than the 10" Meade. My aging eyes don't see any difference between 'em optically. I find the Autostar II controller to be much more capable than the Nexstar, which does matter (if I wanted to drag a laptop around with me I'd have kept my 10" or 12" Classic). The ability to control the microfocuser with the handbox is a real plus (I used an NGF-S on the C11 but had to have a separate control for it). I wasn't able to choose a clear winner myself and ended up keeping the 10" Meade for other reasons (compatibility with my observatory scope). I'd have been very happy to keep either one.

MA for SST and it worked flawlessly. I used velcro to attach hand control to base. I found having to constanly take it off the fork everytime I slewed to different target annoying. Using the rs232 port at base for hand control solved that problem. I Put a piece of velcro on the right side of fork (at base) and a piece on back of hand control.
It did the trick. I found I really dont need a microfocuser for the NEXSTAR. There was practically no image shifting when focusing. Only thing about hand control is you cant adjust the brightness for the readout/screen. Only one setting there. Other than that I found no issues with the hand control. I found the menu easy to use. MARS looked outstanding at Savoy. Used a Nagler 12mm with a orange filter to inhance the Martian terrain. Had a 25" Dobson owner commenting how great Mars looked through my scope. I peeked through his scope and only difference was it looked larger in lens. Clarity was same in both scopes!

I've been content with both the Blue and the Gray focusers for visual use, but find that I can get a little more precise for imaging with a Crayford-style focuser. The Celestron focuser feels better & has less backlash & focus shift but mirror flop is always there. It's a bigger deal on a GEM than the NX11 fork mount, though. Meade's lock sorts that out nicely.
As I say, I could have flipped a coin and couldn't have lost. I like 'em both a lot.

There is an alternative to Velcro! I use this 3M™ Dual Lock™ Low Profile Reclosable Fasteners all the time. It has a nice “snap” when you attach something. It holds items much more securely than with Velcro. You can usually find it at the hardware store. Just an idea.

<quote>You have to complete a GPS alignment then calibrate the compass and level.</quote>
I'm assuming I reset to factory defaults first, do the initial gps alignment, and go into the menu's, and select the 'calibrate' option? What's in vovled in selecting that option. I've seen it in the menu, but the manual is somewhat lacking in proceedure.

I will use it as a backup or while doing astro photography with the 11", I can use the 10" for viewing. I should also consider piggybacking the 10" onto the 11" lol

Which one is better for astro photography (becouse of tracking accuracy) and what is the maximum useable exposition for deep sky objects.

Care to share where you found the NS11 for that price? I'd definately pick one up!
Edit: oops sorry
