other telescope accessories

This battery unit has been usefull to me in the field as long as I don't use a dew zapper for too long (more that 4 hours).

I live in Montreal where it gets pretty cold in the winter (typical viewing session this winter was below zero F.) Using a dew zapper to keep the corrector lens of my Mak clear of frost will drain the unit in about 4 hours

If I use a dew shield and only use the zapper occasionally, I can use it all night but some nights, the humidity gets so high that the dew zapper needs to be on almost continuously, and this is where it is slightly underpowered for a full night of use. And since my telescope drive is also connected to it, I've had to shut down on some nights prematurely.

All in all, a pretty good unit

The 1 star review is about the supplier, and not the light. I am sorry this person had the light destroyed in transit, but I had no problem with an Amazon return on anothe product 4 years ago.

Many lights claim to be 1 or 2 million candle power, and they may be -- if supplied with enough voltage and ampacity, which this one is! This is the brightest handheld light I have ever used! It will light up tree-tops nearly unbelievably. I had a friend with a plug-in 'One Million Candle Power' light, and we made a comparison. There was no comparison. His looked bright, but when I turned on the Celestron, his light looked yellow and dim -- off of a car battery! Therefore, I doubt that his bulb was even rated for 1 million C.P.

Many 1 million C.P. lights have the bulb, but not the battery to drive them. Not the Celestron! It is BRIGHT!!! Yet, it also has a built-in standard flashlight that will last nearly forever (all nigh is no problem at al). This has a flasher and a red lens if needed for a red flasher. I cannot imagine a better light for a trucker, or anyone needing independent power and the brightest "flashlight" I have ever seen. I could write a small book about the ways I have used this, and I have owned it for nearly a year.

It also has sockets of all polarity, including a cigarette lighter plug. This sucker really will help you to jump-start a car! I came in to write this when that became necessary.

It is a bit heavy! All larger batteries are heavy. But, it is quality! And, quality is becoming more rare by the day. You need go no further. Get one! You will not regret it!

I heard a great deal about what a superb product this was. Unfortunately, I've had the opposite experience. I received mine yesterday through OPT by way of UPS. The flashlight was broken internally and didn't work. The floodlight had one of the swivel ears broken. Celestron said send it back and they would repair or replace it at their option - with a wait of 4 to 6 weeks! Their repair facilities have been remodeled and that is part of the delay. I am not impressed with Celestron and will not consider them for any future astronomical purchases! I hope I can find a similar product from another source. I suppose this might be a decent product if you can pick it up in person and inspect it but I wouldn't count on Celestron standing behind it.
