Time for a ‘scope change - question

Recommended Posts

Posted (edited)
Quote

I’m planning to sell my Orion Optics (UK) CT10L f6.3 Newtonian (on Dob mount), and replacing it with a Skywatcher 100 ED or a 120 ED refractor on an equatorial mount. The newt has served me well in the five years I’ve had it, but it’s getting a bit of a beast to carry out to the garden these days - age catches up with all of us eventually!

My question concerns the focussing mount on the Skywatchers, which I’ve read aren’t too good, especially if a camera is attached. I wanted to get some idea of how easy or difficult they are to replace.

Any advice appreciated.

I don't think an ed120 with it's mount will be easier to move than your 10". Perhaps the ed100 on a light alt-az mount will, but in both cases you 'll lose significant aperture, you're already used to, so more likely to miss it....

I've been using a 10" OO F6.3 Dob for the last couple of nights and find it an awkward affair to handle. By comparison my 120mm Equinox was a total joy to use. Even on DSO's the 120ED performed admirably, especially when a good level of dark adaption is attained. Star images are vastly superior in the ED compared to the 10" OO Dob and on the Moon and planets I doubt you'll be at all unhappy. The aperture of the 10" pays dividends with things like galaxies, but even then the 120ED can show plenty of them.

The focuser on my Equinox was adequate enough to hold my 31mm Nagler when the scope was aimed at the zenith, but for imaging you might need to replace it. They are easy to replace!

As an only scope the 120ED makes a powerful and capable easy to use scope that can compete with high end brands.

Thanks for that Mike. I’ve come to the conclusion that as far as deep sky is concerned, visually, one faint fuzzy blob looks much like another.

I just think a good ED refractor will be better for my main objects of interest, planetary, lunar and solar - and much easier to move around. It would also suit webcam astrophotography of these subjects if I try it at a later date.

I have both a 200p newt and the equinox 120  and  much prefer the 120 I do have a permanent  set up so it does not answer you question about portability and set up . I only do imaging but can say I hang a focal reducer and 600d dslr on the original focuser without any problems. I love the equinox 120 and will never part with it.

You wouldn't make a good dob salesman... :grin:

And for the record, each fuzzy blob has a unique shade of grey!

Kiddin - skies & aperture are key.

Can’t fault your thinking. But, with the right finder, there is nothing easier than a Dob. Telrad/Decent Red Dot plus RACI of at least 60mm.

..... and a bigger scope. Yes. You did say that, but the bigger scope is important. I find a 1600mm fl Dob way easier to observe with than a long refractor.

      Looking for the 2" low profile extension tube that is provided with most of the skywatcher scopes. I have a used 190MN that didn't come with the extension tube and need it to get accurate focus. 
       
      I believe Orion scopes may have one too.

      The weights from my NEQ6 are beginning to look scruffy.
      Is there a good colour match car type spray that anyone would recommend for sprucing them up.

      Posting in this forum after too long!
      One of the first attempts at taking photos of the moon.
      All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there.
      No exposure.
      Basic editing in cellphone.
      Thank you! Suggestions highly appreciated!

      Hello all!
      I just picked up a Skywatcher Evostar 80mm Doublett and LX70 (EQ5) mount. This is my first refractor and EQ mount so it took me a while to put it together (if you all notice anything out of place please tell me!). I still enjoy my 8” dob but wanted to learn. This type of scope. It had good reviews for general viewing, but I'm not sure what to expect. 
      The EQ mount took quite some time to figure out and one of my questions is do I operate the scope with the counterweight horizontal to the ground? I noticed that in that position I can use the control cables to move up and down and left and right. Any advice is appreciated!

      Hey guys!i need to make this quick! I want to get a new 6mm eyepiece.I have a 8" f6 dob and i want to get a nice 200 mag and put the telescope to its limits at 400x
      The most i ve seen with is 240x for Jupiter and Saturn .i ve heard they looked stunning at 400x and i am keen on trying it.Ive got my eyes on a 6mm Skywatcher UWA eyepiece.and i have a Bst Starguider 2z Barlow lens.And i seem to be having problems with my 8mm Bst Starguider (300x in total).the bst has a 16mm eye relief and a 21mm lens diameter,but when i barlowed it and look at the moon yesterday,it was hard finding the right spot to look through the eyepiece and when i moved the image disappeared.I dont know if it will have that effect on planets,when I looked at mars it was fine but i definitely want to avoid that from happening again.Will it happen?
      The Skywatcher eyepiece i want to buy has a 16mm eye relief too.I dont want to make the same mistake now , i want a 6mm eyepiece at the price range of 50-70 euro either from flo or amazonuk.If the Skywatcher will have similar results,can you suggest another one?
