I am new in this forum, so I'm sorry if it was discussed, I tried to make a search but didn't find the complete answer.
So, yesterday I've got my telescope, Nexstar 6SE, and I want to figure out, what setup I need for autoguiding.
What I have now:
- Nexstar 6SE. It has autoguide port, so I think, it should work.
- ASI290MC camera, will arrive to me at the middle of the week.
- Sony NEX5, can be connected to a telescope also, I saw T-adapters on Ebay
And some of noobs questions, I have:
1) I need a second small tube for autoguiding. Which one to choose, and how to connect it to the scope? Are there some adapters/connectors on ebay?
I saw "Celestron Guidescope Package", is it what I need? Its pretty expensive, btw. And I don't understand yet how to place it on my tube (duct tape will be not enough? ).
"ZWO 60MM F/4.6 Guidescope" looks also pretty nice, but I don't understand how to mount it on the tube too.
Or maybe the "Celestron off-axis guider" is better? I like that it's pretty compact.
I live in the city and the telescope will be placed on the balcony, so I'm not going to use very long shutters anyway - too much light in the city, and 6/8SE mount, I think, is not mechanically perfect.
2) Do I need a wedge, or with small shutters (less tham a minute) it does not matter? I rent a flat, so I don't want to buy a lot of heavy things. And its $379, expensive for the piece of metal, btw.
3) ASI290MC, it has the autoguide port too. Can I connect it directly to the 6SE mount, or the pinout is different? Do I need to buy the additional cable? After I connect it, can I autoguide through the camera USB connecton only?
And it looks stupid to use 500$ camera for autoguiding only, maybe there are cheap alternative ways?
I'll appreciate the ebay (or other shop) links to the stuff, I need to buy.
