Connecting DSLR to evostar 80ED

[eikie]

Hi all,

 

I own a skywatcher evostar 80ed with which I want to start AP. There is also a Canon 600d underway, however I just found out the .85x flatner/reducer for the 80ed has a horrible order time (1 to 3 months) at most European webshops, including FLO.

 

I do like to start making photos, what do I need to connect my Canon 600d to the scope? Since it is only a temporary solution, until the reducer finally arrives, I'd prefer not to spend that much cash if not needed.

 

I am guessing I still need a m48 adapter, but do I also need some kind of extender? And would that connect to the focusser or do I have to go via the diagonal?

Did your evostar not already inlude a t adaptor?  Mine did when I bought mine a few years ago.  With that all you should require is https://www.firstlightoptics.com/adapters/sw_m48_adapter-1.html.  I'm 95% sure there will be enough focusser travel to not need the diagonal.

Check out a Flattener/reducer from Altair Astro. That are also cheaper than the SW version.

You may also need an approx 50mm extension tube if one wasn't included with the scope

I did get that adapter (I think), but without the extra "tubing" of a reducer, can I really achieve focus?

While most shops I know do carry that brand, I can't seem to find a flattner/reducer.

Also, would that fit correctly?

Would something like this work?

Site is in dutch but basically it's an extender with a T thread (and space for 2' filters)

Yes, that should work ok (assuming you need one, and one wasn't included with the scope), most UK suppliers stock 35mm, 50mm, and 80mm extension tubes, the Revelation brand are fairly inexpensive, and the self-centring ones are best.

The Altair Astro 0.8 Flattener/Reducer is made for the ED80, I've used one for at least 4 years!

Thanks, but also out of stock.  Have they been giving reducers for the 80ED away for free? It seems they are all out of stock and/or have a ridiculous delivery time..

I'm a tad surprised the scope didn't come with the necessary adapters, including the 50mm extension piece (2nd from left). Are you sure it's not in the box somewhere? 🙂

Just checked and it was included. So that's 1 piece of the puzzle I allready have...

I think you probably need the extension tube too, which you should have got with it like me and others:

If not, perhaps using your using your diagonal would work?

I did find that adapter, so only a m48 ring for my camera?

No I was mistaken with my link earlier sorry... the 48mm ring adapter is for attaching to the skywatcher reducer/flattener.  What you need is a t ring such as https://www.firstlightoptics.com/adapters/t-rings.html (perhaps email FLO to make doubly sure).  This is what I have which I know works: https://www.opticron.co.uk/our-products/telephotography-and-digiscoping/t-mounts/t-mount--canon-eos

Thanks, I'll look into that one...
