    Default Upgrading an 8SE



    I think I might find the answers to some of these if I really looked, but I don't have the time..lol. I was inquiring about the effect or even possibility of upgrading the following on an 8SE. I know "necessity" really doesn't come into it too much, but we do like to tinker don't we"

    1. Focuser - is it even possible to upgrade a focuser on an 8SE? And would I wan to?

    2. Diagonal - Ive read mixed reactions to this. Some say its the most regretted waste of money, others say its a nice upgrade.

    3. Aside from #2: moving from 1.25 to 2 inch. Big difference?

    Anything else that would be fun? Those Televue Everbright prisms get some awesome feedback in the reviews but I suspect they might be written by actual TV employees. Who knows?

    Got any other bright ideas? I'm just sitting inside waiting and waiting for the clouds to disappear. Idle hands and all...

    You could buy a moonlite focuser for that telescope. Its dual speed. I wouldn't mind having one, but not sure they are necessary unless you are involved in AP. Nice piece of kit though.

    Did you get the diagonal that is Starbright xlt coated? if you did it's a pretty good diag. I see a lot of people who have upgraded from stock Diags to Williams Optics ones. They get really good reviews.

    As far as eyepieces, most of these guys say 25mm and up go with 2 inch eyepieces. They are good for low power wide field viewing. 24mm and lower, stay with the 1 1/4 inch eps. you dont really gain anytinging below 24mm in the 2 inch format.

    The very best thing you could do is hook up with an astronomy club in your area and go to a few star parties. You can get hands on help and see for your self before you spend your hard earned astrobucks. I know theres a couple really good clubs in your area.

    Good luck and clear skies to ya

    Craven, a lot of guys use either the Starlight Feather Touch model FTM-CPC8 focuser as a replacement on their scope:

    Starlight Instruments Feathertouch Microfocuser for Celestron CPC 800, NexStar 6SE & 8SE - OPT Telescopes

    or the JMI motofocus:

    http://www.jimsmobile.com/images/mf_nex6.jpg

    Both offer much better focusing than the stock unit.

    Based on a lot of expert advice on this and another forum and based on the popularity of this particular diagonal, I upgraded to a 2" diagonal:

    William Optics 2" Carbon Fiber Dura-Bright Mirror Diagonal with 2" to 1.25" Adapter

    Then based on the reports of the endless users who use the Hyperion MKIII zoom 8-24mm EP, I bought one of those. There is an endless thread on this forum dealing with the EP. I find myself no longer using anything else.

    Baader Hyperion Mark-III Clickstop Zoom Eyepiece 8-24mm

    BTW, should you be interested in the JMI motofocus, I have one for sale.

    C raven:

    To be honest I do use a 2" Diagonal...and an expensive ($500) dollar one at that....BUT to be honest the OEM 1.25 inch diagonal that came with your scope is NOT a bad diagonal.... You "may" see 2-3 percent better with a "good 2 inch Diagonal...seriously...

    The main advantage you get out of a 2 Inch Diagonal is the ability to use wider field low powered eyepieces... I use a Denkmeier P/S most of the cost is in the Power switch which allows me to push a leaver and stick a 2x Barlow in the optical path in a millisecond OR push the other lever and stick a 0.67 Focal reducer in the optical path...so it does it functions as 3 different pieces of equipment and is a major time saver...

    I use a Motofocuser on my scope...simply because I do not have to touch the scope and give my OTA the shakes (caused by the tripod btw NOT the mount)... Over the years I;ve gotton so use to it I switch it onto my CPC1100 when I am not using it on my 8i (earlier model of the 8SE)

    Beware however that some 2" diagonals will not clear the base of the 8SE unless you add Rons Rail or Eddies Bracket to the scope (cheap and effective method)...

    All of these things rank well below a Good Dew Shield and Power supply and a GOOD solid adjustable chair...

    Upgrades I made to mine - purchased 9/10:

    GSO 2" diagonal - allows me to use of 2" eyepieces
    GSO 8x50mm RACI - like it better than the red dot finder
    Bob's knobs - helps with collimation
    Hand Control Mounting Bracket (JMI) - easier to use the hand controller
    Feathertouch SCT MicroFocuser - allows for fine adjust and helped with OTA movement while focusing.
