...now my screw aren't even tilting the mirror. I can't figure out at all how to get this collimated. I have been trying basically all night. So frustrating... another night lost.
Waveform said:In the end I found out the spider was defective and prevented a good collimation.
This is probably not the case here. I am under the impression Orion produces good scopes.

I am suspicious of his secondary position. Because he has the focuser stroke problem in addition to the collimation problem.
Sheneron said:The ones that connect the spider vane to the tube?
Sheneron said:Would it be acceptable to bring my telescope to the club on the very first time I meet them? I don't want them to think I am using them.
Also, I understand the collimation process quite well at this point. .

Thanks again everyone. Clear skies.
Orion is a well-respected company, so their Barlows should be reliable. You don't have a collection of eyepieces yet, so here is your conundrum: You can choose from several powers of Barlows, including 2x, 2.5x, 3x and the choice should hinge on the amount of flexibility that the Barlows will allow you. It is possible to get some very high effective magnifications with Barlows while retaining the eye-relief of the EP that you plug into it. Still, you should avoid duplication of powers. If you had EPs like 12mm, 24mm, 48mm, it would be pretty silly to buy a 2x Barlow because all you would get from that is an equivalent 6mm EP and duplication at the other levels. Good EPs are expensive, so it's a good idea to choose a high-quality Barlow, and choose the multiplicative factor carefully so that you can get a wide range of powers with a modest number of EPs.Sheneron said:How do these barlows look?

And would you suggest building my own solar filter or purchasing one? I am a little cautious about building my own seeing as my vision is depending on it, but it is farily easy?
