Celestron 93640 overview

  • 1Description

Ultratelephoto photography is easily achieved with your telescope by purchasing this Celestron SLR Camera Adapter with Integral 2x Barlow Lens.  You'll need to take precautions to minimize vibrations, such as locking up the mirror if possible as well as using a cable release or remote control to fire the shutter.  This SLR adapter's got a built-in 2x barlow lens to assure that any telescope can achieve proper focus, but many telescopes will be able to use it with the barlow attachment removed if you prefer.  It will depend upon how much in-travel your focuser barrel has at its disposal.  It can, of course, also be used on a catadioptric scope which has a 1.25" focuser barrel.

First, remove the eyepiece. Next, attach the SLR camera adapter where the eyepiece would normally be attached to the telescope, and screw in a T-mount adapter to the opposite end of the SLR camera adapter. Now you can attach your camera to the T-mount and you are ready to begin taking pictures!

Note: Your camera will need to be in fully manual exposure mode, although some brands of camera may also work in aperture-priority autoexposure mode.  Additionally, if there is a switch on the camera which chooses the focus mode, that switch must indicate manual focusing.

Inserts in to 1.25" focusers
Requires T-mount SLR adapter (listed here as accessories)
Incorporates 2x magnification
Built-in barlow lens can be removed (some telescopes will not focus properly without barlow)

    SLR Camera Adapter with Integral 2x Barlow Lens is rated 4.2 out of 5 by 25.
    Rated 3 out of 5 by from First Time with an SLR adapter Being my first experience, I'm not sure what to expect, but am not so happy with the results. First off, my scope is 1250mm, which is difficult enough to stabilize for viewing, and with this 2x on it for the SLR, I have not been able to get a stable shot yet. I figure that more practice will help me to get better at it. I figure that the 2x might be causing me more problems, so I ordered the single adapter and will see how that works. I also get a white spot in the center of every photo. Again, this may be due to my inexperience in how to use these properly.

    Rated 5 out of 5 by from This is a very versatile adapter. I brought it to use on my Nexstar 114 GT and it works very well. The Barlow x2 lens can be unscrewed so it can be used as a straight adapter as well as a x2. Luckily my micro four thirds camera adapter has enough room to allow the 10 eyepiece to be fitted as well. This gives me four different magnifications that I can use. Unfortunately my 25 eyepiece is too large to fit within the camera adapter. My images are quite good but I would like to sharpen then up a little. I think I need to work on my shutter settings to reduce shutter shock when shooting the moon, and take care with my telescope setup for better tracking when shooting the planets. There is a little play when fitting to the scope, but this is the same play that both my eyepieces have.

    Rated 5 out of 5 by from Got a great photo of the moon! Once I received this lens, I attached it to my Canon Digital Rebel XT using a T-Adapter and was able to finally take a picture of the moon through my Celestron 130 SLT telescope. Previously I had used another lens, but could not get anything in focus as the lens was basically just a metal tube. Without this device, I would not have been able to accomplish this.

    Rated 4 out of 5 by from Great for price So far used for digital photography with microscope. Plan Telescope use. Parts and threads fit fairly well. The barlow lens is so so. Mixed metal and good hard plastic product. Fits T adapter well. Pleased with product relative to its pricing.

    Rated 3 out of 5 by from Use with SLR adapter It fitted nicely onto my Sony DSLR using the T-mount adapter. I'm using it with my Celestron NexStar 114GT with acceptable results, hope I'll be able to improve as I get more used to. The side screw was too tight and there was a small burr in the inside, and I thought I should return it, but I was eager to try it, and decided to remove the burr. I scratched a bit the interior of the piece in the process, but it did not affect the performance. The lens can be removed and used with other eyepieces,which is a nice feature.

    Rated 4 out of 5 by from It works Used with 6 Newtonian. Had tried a non-magnifying T-adapter but couldn't get the camera close enough to focus. This did the job. Moon fills up entire frame. Remote release is a must (I used a corded one).

    Rated 5 out of 5 by from Works great Using this camera adapter I was able to attach my Canon DLSR body directly to my telescope. It works perfectly and I am taking awesome photos of everything in the night sky.
    Date published: 2015-07-16
    Rated 4 out of 5 by from Very economical barlow for photography I imaged both Jupiter and Saturn and a bright star using the C14. The adaptor is very economical and all you need extra is an extra $ T mount fitting and you can start.The camera attaches very nicely and it fits snugly into the C14 just like an eyepiece(with the right angle prism removed.) It is a much simpler process than prime focus photography alone where you need to fit a special adaptor.The resulting image was quite large and I did notice some fringing colour, but this may have been due to lower altitude. However the barlow is clearly at the cheaper end of the spectrum.Bear in mind when using this device that the image scale will be such that you are at the mercy of atmospheric turbulence. Also you may need to take precautions from DSLR 'shutter shake'. A 'live view' mode if you have it, is one way to go...
