Looks like 14.3 volts for constant voltage charging would be best (more on this later, stay tuned).
Put another battery in it, charge circuit shuts off when voltage reaches 12.7 volts.
.
Anything < 12.3 causes sulfatiion.
"Sulfation of batteries starts when voltage measures less than 12.4 for a 12v battery"

Celestron 6" SCT (C6-A), Orion Sirius, GSO 2.0x Barlow, Canon 7D, Thousand Oaks Glass Solar Filter tethered to an old refurbished Dell laptop. Looking at the day star.
Eyepiece shown is not the one supplied, but produces the maximum power before image breakup.
Wonderful mechanical design, the tube is even made of steel, can't say the same for optics.
Solid and smooth pointing motions.

The only reflector of the bunch, the celestron 130SLT with goto, red dot finder. Used for quick snaps (as alt-az mounts lead to field rotation, which rules out anything that requires a long exposure). A fairly fast scope used with a CCD that can take very short exposures can work well... 130mm aperture, 650mm focal length.
I've been watching this Osprey Nest for some time. The problem is that it's so far away (1/4 to 3/8 of a mile). This photo was shot with a Nikon D7000 attached to a Celestron 90 SLT telescope.
Setting up at Shawmut. Looking forward to the Sun going down and Omega Centauri popping over the southern horizon in a few hours.

Primeras pruebas de la cámara celestrón NexImage en un telescopio Astromaster 76
Recién cambiamos el ocular de 10mm por la cámara.
Very first tests of the NexImage camera in telescope Celestron Astromaster 76.
We just changed the 10 mm eyepiece for the camera.
Team Celestron returns to the NorthEast Astro-Imaging Conference in Suffern, NY. We saw lots of familiar faces and even got the chance to check out presentations by expert astroimagers.

This was my first time ever to try photograph comet.
Tracking was not working after adjustments I made to mount. (One screw was loose). I got only a few shots after clouds filled the sky.
This is a single shot
Team Celestron unveils new products at CES 2014. Interviews with CES Live and Tech Podcast News, along with our first-ever double decker booth with observation deck!
I picked this 1980-ish mirror lens up on flea-bay, so it warrants the obligatory test. The green window near the centre has a bar down the centre.I guess that this is about 3 inches across.... roughly 2.5 km away. I get that this translates to the resolution being better than 6 arcseconds - comparable with what the 40D can achieve at this focal length. Don't let the lights fool you - these are heavily blown out (and they're not point sources anyway.) On the whole, I think it's quite excellent!
