    Default Suggestions for first equipment?



    Hi!
    I am planning to get the Nexstar 130 SLT around $320 from Telescopes.com. With a budget around $400, I have some extra money to spend. I am wondering what the best thing I can get with the extra money. Things included would be...
    • Damper pads
    • Eyepiece(s)
    • Barlow lens
    • or anything that I may "need" that you suggest

    I am converting from a Celestron Powerseeker 114az that did come with lenses and a 3X barlow lens, but am sure they are not the best quality (as was the scope). Obviously, I am trying to upgrade from the old stuff, and at the moment can only spend a little extra on equipment. If you have any suggestions, please let me know. Thank you!

    In my opinion you truly need an external power supply unles syou have unlimited money to spend on AA batteries Plus like to see the scope dance all over the sky when those batteries get mayme an hour of use on them...

    Powertanks are more expensive then Wal Marts (and sears, and pep boys, and auto zones) quick start battery chargers and are no better...

    I would then look around the house for a chair you could disappear with or buy a good rock solid observation chair FOR YOUR EYES not for you tail end..or legs...

    I'd use the eyepieces you already have (including the barlow) for a few months BEFORE I even gave a though to what additional eyepeice I may want to buy....

    WAIT until that Want turns into a NEED ....

    Bob is correct on this. Spend the at most 25 bucks on the power adapter. These mounts do not work with batteries.

    As far as vibration dampener pads, that can be had for about 7 bucks at walmart with those furniture mover hockey puck looking pads along with felt pads about half the diameter of the moving pads superglued to them, along with NOT extending the legs in the mount all the way, PLUS a ten pound weight hung down the middle from the accessory tray with one of those bungee cords. That pretty much elminates all of the vibration.

    Does the (in my case an AC adapter) have to be a specific amperage? Have a bunch just lying around the house that I'm sure would fit it.
    If I ever get a battery pack, what would you suggest I get, and where?

    AC adapters work, but not perfectly. I can run my motorized mounts with converters with as low as 500Ma outputs. The ones I picked up at the junk store for $2 each seem to put out a higher voltage than they are rated for, which translates to the motors running slightly faster. Fine for visual, though, as the target stays in view for at least half an hour.

    The Source sells multiple voltage ones for less than $40. Try to get the output voltage as close to 6 as possible.

    DO NOT GO BELOW 2.5 amps.... And PAY attention to the actual size of the connector as Celestron for some reason uses a non standard or smaller then normal size connection...

    That said...Unless the power supply is regulated you are exposing the electronics of the scope to "possible" damage if you get a spike from the adapter ..

    To me personally I will NOT run on a/c power even with my CPC1100 which is pier mounted in an observatory with 10 electrical outlets none are even 6 foot away from the scope....

    Batteries just can not damage your scope...

    Just my opinion and I'm NOT the type of guy who gets **** over these things but sometimes you have to take some minimal precautions ...

    I agree with Bob, one day that cheaply made 110volt wall wart will SPIKE and take out the main circuit board in the scope. Happens all the time-- and keeps Dr. Clay in business.

    Also NEVER plug or unplug any cables while the scope is turned on.

    I don't know if this is a secret or not, but if you add in a zhumell item to your order at telescopes.com then use the 10% off code (off the front page) it applies to your WHOLE order. This will stretch your dollar a little further. I picked up the AC adapter for my mount (which should be the same as yours) for about 24 bucks (10% off). It works like a charm so far. I also picked up a 3 piece EP and moon filter set from meade for $59.99 off ebay, purchased it from seller "opticaloverstock" they shipped it VERY quickly and I received it within 2 days. I am still a newb, but for my uses the eye pieces work pretty well. Your mileage may vary.

    Edit: Here is my original post:
    Zoom lenses?

    It contains some other information on eyepieces and things to consider as well as a link to the Meade eye pieces, and proper credit for the useful information I received .

    Gremsor,
    thanks for the tip! I might just have to do that now....
    So I think what most everybody is trying to say, is that a power tank is better? If so, I might add Celestron Power Tank 12v Power Supply 7 Amp Hour for Computerized Celestron Telescopes from telescopes.com. Any oppositions?
