What is the difference between Meade LX90 and LX200?
The LX90 lacks the primary mirror locking that you get with the LX200. This can help when it comes to astrophotography, though many people don’t use this locking feature anyway. You can also lock the mirror down with the LX200 too. The LX200 comes with an additional Meade micro-focuser that you don’t get with the LX90.
Is Celestron better than Meade?
Meade and Celestron are both top brands in the telescope business. It does not seem Meade is any better or worse than Celestron as both make great products that can last a life time with proper care and use. However, Meade’s prices are much higher compared to Celestron, which may help you decide what brand to go for.
What is Coma Free telescope?
Telescope Designs Free from Coma Some telescope designs are free from coma. Classical Cassegrain telescopes, for example, have coma inherent in the design. But by slightly changing the configuration of the mirrors, the very similar Ritchey-Chrétien design eliminates coma but instead suffers from astigmatism.
What is an ACF telescope?
ACF telescopes ACF (Advanced Coma-Free) is an altered version of the Meade’s previous schmidt-cassegrain telescopes that replaces the traditional spherical schmidt-cassegrain secondary mirror with a hyperbolic secondary mirror.

What does coma look like in a telescope?
Coma is an aberration that occurs predominately in reflectors and manifests itself in the appearance of ‘comet-shaped’ stars with their brightest portion pointing towards the centre of the field of view.
What does coma aberration look like?
Coma is a complex aberration that affects only light rays from a point that pass through the lens at an angle. With coma, the rays don’t refocus to a point, they flare out from the point (Figure 9). This makes points of light look like a comet with a blurred tail, hence the name.
Is Meade going out of business?

What makes the Meade LX90 so special?
Meade’s LX90 also features Ultra-High Transmission Coatings (UHTC™). UHTC™ are specialized multi-layered coatings that are precisely designed to improve the performance of your telescope’s optics. You’ll see brighter star clusters, more fine detail in nebulae, and additional surface features on planets.
What is the focal length of The LX90 series ACF™ telescope?
Where To Buy? The LX90 Series 10″ ACF™ Telescope features a 10″ aperture, 2500mm focal length, and f/10 focal ratio with Dual-Fork Mounting.
What kind of Mount does The LX90 have?
All LX90 models feature a solid and stable aluminum double-fork mount with fast slew speed adjustable from 1.5° to 6.5°/second. Mount and electronics are internally powered by (8) x C-cell (user-supplied) batteries, which will typically operate the telescope for a generous 60 hours (optional Meade Universal AC Adapter can be used).
