    GOTO refers to commanding the mount to point the telescope towards a specific object or location in the sky.

    Hand controllers do not like the cold. Attach a chemical hand warmer (Hot Hands) to the back of the hand controller with a rubber band.

Also, it was about 29 degrees and I had trouble with the hand controller moving the scope -- is that to be expected?
    Thanks for any advice,
    Sandy
    Make certain you are entering the time, date, and location properly. Answer 'No' to Daylight Saving Time. Be certain of the alignment stars you are using.

    What mount do you have with the 8SE?

    A few pointers from a fellow nexstar owner:

    1. A lithium powerpack is essential in the cold. I use this one and have no complaints. Low voltage makes the mount act funny and the cold drains alkaline batteries.
    2. I have had the most success using the two star alignment method. If you can see Polaris from your observing location you only have to know the location of one other bright/recognizable star. Betelgeuse is my go to this time of year.
    3. The celestron GPS unit is pricey, but is a very nice luxury to have if you can afford it. I purchased mine shortly after forgetting to bring my phone/watch out observing with me. The unit provides date, time, and location information to the mount automatically.
    4. In the cold months I stick a hot hands toe warmer to the back of my remote to keep the LCD working properly.
    5. No doubt a reticle eyepiece will help you get more accurate alignments. The batteries in mine died last year and I haven't bothered to replace them. Most of the time I just defocus my alignment star and center in my 12.5MM eyepiece.

    Good luck with the scope and clear skies!

    Hello -- I am working my way through the Nexstar 8se manual and I find that the labels on the buttons of the hand controller do not correspond to the instructions in the manual on the "Object Catalog" (page17). I don't have a "list" key. I do have "stars" and "solar system" (obvious even to me), but how to I enter something like Messier 44 (the beehive)? Also, I see people talking about "goto" mounts. I don't know what that refers to. Thanks for the patient help.

    I checked my manual and it seems you are right! It looks like an image of an old controller layout. To see Messier 44 (M44) you would hit the DeepSky button (#3). Then Select Messier from the list of catalogs and type 44, then Enter. Your scope will then "Go To" the object if it is above the horizon and within the ability of the scope to see it. If it is too high or too low the scope will not be able to "Go To" the object due to it's inability to go there (slewing parameters). You pretty much would need to wait.

    I just checked M44 and it should be about 58 degrees above the horizon tonight at 8pm, so the "Go To" should work. Assuming you are properly aligned.

    Good luck.

    A "goto" mount is a mount that can find and go to a specific object in the sky. Your SE is an example of a goto mount. A camera tripod is an example of a non-goto mount.
