Attaching my DSLR to my Skywatcher Skyliner 200p Dob

[farren272]

Hi all,

I know that lots of questions seem to get asked many times but I always find that I'm missing one crucial bit of info (which normally just means I'm not understanding something).

So, I have my scope, and I have me DSLR (Canon 60D), and I have my T-Mount, and I know know that I have all I need to direct attach them all together.

But now I'm confused, because as there are not going to be any eye-peices between the scope and the camera, I don't understand what field of view I'm actually going to get.. if any.

Am I asking a silly question?

You don' use an eyepiece - the scope acts as a fixed focal length "lens" and creates an image directly onto the camera sensor. Try this freeware: http://www.newastro.com/book_new/camera_app.php Just put in your camera and scope and it will calculate and show you the fov you are getting.

That's a great app.

The field of view will be the same as with any 1200mm lens, if you're used to terrestrial photography that might give you an idea.

What exactly is the 200p dobsonian?

If it is a manual variant then imaging of any type is not really worth thinking of - The Moon being the one exception.

If it is a goto then it will at least track and so be OK for planeraty imaging with a webcam.

If you are thinking of DSO and long exposure imaging then the setup isn't really suitable.

You can get t-adaptors that hold an eyepiece internally. 'Eye-piece projection' gives you more magnification in your pictures

Thanks Ronin,

And yeah, it's just a dob mount with no tracking etc so I know I can only really get shots of the moon and small fuzzy pics of Jupiter.

I can already see that I'll be upgrading to the an EQ mount with tracking at some point but was just interested to see what I 'could' get with the current basic setup.

Cheers

Hi,

Do you have a link to such an item?

Just having a google now but not sure which t-adaptors are going to do what I want.

Alan at 'Skies unlimited' on e-bay sells eyepiece projection adaptors: ebay.co.uk/skies_unlimited/ . The adaptors themselves take some getting used to and are not intuitive, but can produce some good results. (Alan, by the way, is a well known and trusted retailer - especially of the BST eyepieces).

Thanks, I'll take a look.
