Celestron 93665 Wedge for NexStar Evolution/SE, Black

This product is well constructed and operates as advertised. It was easy to install onto a Celestron NexStar 8se mount. The tracking of the scope with a CCD camera has improved with this device. Polar alignment, combined with Celestron's SSAG product, is very easy and accurate, especially when compared to using something like the PHD2 software and a guiding camera.

Allows me to accurately track the stars and planets with my Evolution 8HD. Makes the longer photographic exposures much easier. A bit heavy, but you want that in a good build. A good step up product for the beginner and more than novice astronomers.

Excellent service and quality product.

This is an excellent, heavily built wedge! I purchased it for my Celestron nexstar 6se and was very impressed with its solid construction and nice design. I have a wedge for my 12" Meade lx200 classic that is just a collection of metal slabs bolted together which Meade thought was high design in its day, this one however actually has some nice touches to it when contrasted with my old lx wedge. The anodized parts add a nice touch of color and the hooks for hanging the hand controller are thoughtful but maybe placed a little far back on the wedge. There are cutouts to reduce weight but they add a nice touch of design. The azimuth adjustment controls are awesome for when you need to dial in a fine adjustment while polar aligning. I'm excited to start using this and look forward to many nights of astrophotography using the excellent 6se and it's amazing optics.

This looks and feels like a solid piece of engineering. Strong and precise build. I used it to convert my 8 inch Celestron SCT from Alt-Az to EQ. Does the job perfectly. Instructions for mounting are easy to follow. This was a great purchase.

Solid built but single fork is lacking strength I have the 9.25 evolution the wedge is solid and I was very impressed buy the build which explains the cost, but I have to set 10 alignment points to get it close to working the issue is the single fork arm, it is designed to operate upright, but the wedge has it hanging under to fork standing on top and in any other conceivable position other then vertical and it appears to cause flex in the arm. So to find a deep sky object you have to align to a bright object near by to compensate for the flex. Going to try it one more time before I return it and look at a polar mount. Got another clear night and found that you need to pick alignment stars about 90 degrees apart and that if you find a bright star near the deep sky object you can align on it then move to the deep sky object. I took photographs to show the stresses on the single arm. the photos are taken with a cannon t6i with no processing. RC car batteries are for the dew shield heater. The first Orian nebula is without wedge second is with the wedge the 3 photograph is the sculptor galaxy and is a multi minute exposure. After months of fighting with it, I broke down and bought a CGX Mount. When I spoke to celestron support they advised that the 9.25 is to heavy and will cause prior performance, probably why it is not mentioned in the product description.

This is very heavy duty! it is also heavy in weight! Quality piece to adapt your electronic mount to.

I save a few $ by buying an open box item. Amazing improvement over no-wedge days for sure. I think this is a nice step forward in my astro imaging adventure before getting a dedicated EQ mount eventually (I can't expect too much from a single fork Evolution mount in long term). It makes 8-15" unguided exposures almost streak free. 30" not so much. Need to try with more ref points than one next time I am out :) Also its extra added weight absorbs vibrations nicely and makes whole setup more stable. Pro tip: you will need an illuminated cross hair eyepiece for your polar alignments!

Excellent product. Solid and easy to adjust, the weight is necessary for a solid platform for the telescope. Polar alignment is a cinch!

Es una excelente opción para los que no podemos conseguir una montura ecuatorial tan fácil (ya que su precio es por lo general muy elevado). Cumple su función, ayuda mucho para astro fotografía de objetos de espacio profundo ya que elimina la rotación de la imagen. Cabe mencionar que no ayuda mucho a alargar los tiempos de exposición de las fotos ya que la montura (de un celestron Nexstar 6SE) solo permite exposiciones de máximo 40 segundos pero les ayudará tener autoguiado, lo cual apenas tuve oportunidad de probar y aparentemente se puede prolongar más el tiempo de exposición de las fotos aunque no he probado hasta que punto. Un punto a considerar es qué hay que buscar en internet cómo hacer la alineación ecuatorial con la cuña ya que en el manual del telescopio ni en el de la cuña explica cómo hacerlo. A final de cuentas, es accesorio recomendado si van a hacer astro fotografía, no pueden conseguir o no quieren invertir en una montura ecuatorial, van a hacer autoguiado y están conscientes de que aún con la cuña no van a poder lograr exposiciones demasiado largas.

So heavy and sturdy

The Wedge was delivered super fast. Thanks. However, when the packing was opened I found one of the two Azimuth Adjustment Knobs was twisted and bent. This has apparently not happened due to packing. I doubt the packing has been done knowingly and regardless of this so-noticeable damage. I'm very disappointed as I did not expect such high-end, reliable product being delivered with such negligence. Except for this defect, the product is of usual high standard and quality. (If needed I can send you the photos of this damaged knob). Could have given five stars to this product but for this defect.

Muy buena calidad. Muy robusto.
