    Could you explain what you mean by a "gotos?" I'll look into a reticle eyepiece.

    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,

    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!
