Product details


Product Description

Manufacturer's Description

Meade LXD75 - Series telescopes provide a new level of sophistication and precision at a moderate price and include the exclusive Meade LXD75 equatorial mount with Autostar control system. Manufactured entirely at the Meade Irvine facility, LXD75 series diffraction-limited Schmidt-Newtonian optics yield pinpoint stellar images over extremely wide fields, with one-half the coma of paraboloids of the same focal ratios. Combined with the fast f.4 optics, the standard equipment Super Plossl 26mm eyepiece yields an actual field of 1.3°, for brilliant, rich-field imaging of nebulae, galaxies and star clusters. The new Meade LXD75 German-type Equatorial Mount has been designed by Meade engineers and is manufactured of machined aluminium for high performance photo-visual observing, moving effortlessly across the skies in either tracking or automatic GO TO modes. Manual fine-adjustment controls in azimuth (horizontal) and elevation (latitude angle) facilitate alignment of the mounting to the celestial pole; the standard-equipment polar alignment viewfinder, with illuminated reticle for easy visibility against the night sky, provides confirmation of precise alignment. The Autostar Dual-Axis Electronic Control System is of advanced electronic design and is included as standard with the LXD75. It offers automatic GO TO facilities at 4.5°/second on both axes simultaneously, to 30,223 database objects.

Guide, measure angle of arc, and Az in one EP 23 Jan. 2011
By Greg S Pecaut - Published on Amazon.com
Verified Purchase
A very virsitle EP. Lots of fun for helping take better observation notes. Calculte size and distances with the EP. Can be used for drift alignments, but I prefer a simpler double cross hair EP for this.
The illuminator works fine, but is not a pulse type, though it can be screwed off and a pulse used instead. Optics are simple good old Meade EP optics, but then you use this EP for measurements more than observing fine details.
You will need to do a little math to measure the diameters of craters or distances with this EP. It can also measure the separation in minutes and seconds of double stars. Using the protractor built into this EP you can align it to measure angles (Az) from target to target, and with the linear scale distances. (you need to do the math based on the scope you are using the EP in). Has a very small double cross hair reticle in it also. So it can be used for drift aligning your mount too, or if you have the patience manual guiding. The EP does barlow well, with all of my 1.8X, 2X and 3X barlows.
This is not the EP you want for lining up you alignment stars for a Go-To scope, nor for manual guiding. The simpler double cross haired illuminated EP is used for that. It is a fun EP to play with, and can help you take much better observation notes.

Really useful eyepiece! 16 Dec. 2009

For centering a star, collimating, determining angular distance, you won't find an eyepiece as effective for the price!

Good eyepiece for performing measurements... but a couple of caveats 14 Nov. 2013
By T. Campbell - Published on Amazon.com
Verified Purchase
The eyepiece itself is essentially a regular 12mm plossl -- but it has a reticle with several patterns for measuring angles and distances.

One of the patterns is a distance scale. You have to do a tiny amount of work to calibrate this scale to YOUR telescope, since the focal length of your scope will alter the angular distance of each division on the scale and the instructions to do this are the first problem with this eyepiece (the eyepiece is fine... the instructions are wrong -- more on that in a moment.)

Another factor I noticed (but very common to eyepiece with built-in illuminators) is that the dimmer on the illuminator is a bit flakey. I removed the dimmer knob and put a drop of contact cleaner on it and exercised the knob a bit to work the contact cleaner through. This resulted in MUCH BETTER performance. It may need more than one cleaning (mine started to get flakey again after a month or so but not nearly as bad as it was when it was factory new.)

About those instructions... Meade will tell you to point your scope at a star near the zenith (directly above your head relative to the ground) -- which is wrong. They'll also tell you that a star moves at 15 arc-seconds per second. Which is also wrong for most stars.

The stars don't really move... the Earth spins. A star near the Earth's poles will appear to hardly move at all. A star located above Earth's equator will appear to move considerably faster. This is the flaw in Meade's instructions. Incidentally, it's those stars above the equator which seem to move at about 15 arc-seconds per second. You can calculate the actual movement... it's the number of arc-seconds in a circle (360 x 60 x 60 = 1,296,000) divided by the length of a sidereal day (23h56m04s - note... NOT 24 hours... that's the length of a solar day which accounts for movement of the Earth in it's orbit around the Sun) converted to seconds (86,164) which works out to 15.04 arc-seconds per second.

To calibrate the distance scale to your scope, find a star which, in the RA/Dec (right ascension / declination) system has a declination value very close to 0º (which means that star appears to be located above Earth's equator - stars near the poles have a declination near 90º (or -90º in Southern hemisphere).

To determine the angular separation of each division on the scale, for a star with declination 0º (above the Earth's equator), place the star at one end of the scale, stop tracking the star (so the star can drift one side of the scale to the other), and count the number of seconds it takes for the star to go from one end of the scale to the other. A star at Dec 0º moves at about 15 arc seconds per second. So multiple actual seconds by 15 and since there are 50 divisions on the scale, divide by 50 and that's the distance per division.

If the star is not at declination 0º, then multiply the number of seconds by the Cosine of the star's declination. E.g. if it takes 90 seconds to go from one end of the scale to the other (do several runs and get an average) and the star has a declination of 20º then it's:

90 * cos(20) * 15 / 50 = 25.37 (which would mean that each individual division on the scale represents 25.37 arc-seconds.)

The general formula is: <seconds> * cos(<star declination>) * 15.04 / 50
where <seconds> is the number of seconds it takes a star to go from one end of the scale to the other
and <star declination> is the declination of the star you are using to to perform the measurement.
15.04 is the actual number of arc seconds of movement per second for a star at declination 0º (but you are multiplying by the cosine of the declination which will adjust for this)
50 is the number of divisions on Meade's scale.

This is just an example because the ACTUAL value will depend on the focal length of your telescope.

I used this eyepiece to measure double star position angles last weekend. It worked fine. My only comment is that I wish the illumination control worked a bit better, I can't dim the reticle as much as I would like. Still was able to make all me measurements though so not a big deal.

Sometimes a bit flaky! 1 Dec. 2011
By Odinaz - Published on Amazon.com

I was pleased with the lens when I first got it and it worked wonderfully. Then, within a couple of months, it started 'flaking out' on me. Sometimes it would illuminate and sometimes it wouldn't. I thought it was a battery problem, but it wasn't... it was just flaky! For what Meade charges for this lens, I wish I had looked a little further and found a better quality eyepiece. Oh well, that is the state of products on the market today, I guess. I gave it a 2 stars because it worked for a couple of months, if it operated when I got it like it does now, I would have given it 1 star and sent it back. You decide.
