  • Baader 2" Mark III Multi-Purpose Coma Corrector for Dobsonian OTAs

    An ideal visual and photographic tool for fast Dobsonian optical tube assemblies (OTAs), the Alpine Astronomical Baader 2" Mark III Multi-Purpose Coma Corrector (MPCC) improves your views and image quality on any OTA with a removable 2" collar. It eliminates distracting off-axis comas and ensures stars remain tack sharp all the way to the edges�without adding any magnification, reducing the focal length, or narrowing the field of view.

    The MPCC is optimized for fast f/3.5 to f/6 Dobs and will transmit enough light to completely cover today's large DSLR camera and CCD imager sensors without vignetting or requiring addition back focus distance. Phantom Group Multi-Coatings maximize transmission through the visual bands while blocking ultraviolet (UV) and infrared (IR) wavelengths to prevent ghosting by sensors that are sensitive to them. The MPCC has standard 2" eyepiece filter threads and a second set of male threads that match their T-2 Astro modular accessory system to give users access to a wide assortment of adapters and rings that allow the corrector to be attached to gear from eyepiece holders to imagers with relative ease.

  • Baader Deluxe 1.25" / T-2 Eyepiece Holder

    Part of their T-2 Astro modular accessory system, the Alpine Astronomical Baader Deluxe 1.25" / T-2 Eyepiece Holder is designed to provide a reliable and simple way to hold your eyepieces, diagonals, Barlows, or other accessories.

    It is made with tight tolerances to minimize sloppiness and has three clamp screws to ensure the eyepiece is centered and accurately optically aligned, with a bronze compression ring to hold your gear without marking or marring the nosepiece. To help ensure tack-sharp images, the holder has a micro-focusing mechanism with 5mm of travel and a lock to set the focus. Standard T-2 internal (female) threads are machined into the telescope side of the holder.

  • Baader VariLock 29 Extension Tube

    Part of their Astro T-2 modular accessory system, the Alpine Astronomical Baader VariLock 29 Extension Tube allows you to set your perfect extension length and lock it in for the precise focus distance of 20-29mm. An engraved scale on the tube lets you note the selected length for future repeatability. Both sides have standard T-2 threads to make it completely compatible with all rings, tubes, holders, and other parts of the Astro T-2 system for creating custom visual and imaging rigs.

    Beautiful, and everything I want it except that the keyboard keys didn’t work😭
    Color: Light Pink
    I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.

    Great quality at a remarkable price
    Color: Navy Blue
    I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews. The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available. The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.
