Astronomy/Focusing with a reflector
Expert: Ed - 10/29/2005
QuestionHi:
I just bought my second telescope and it is a reflector 114mm aperture, f/4.4. The problem that I encountered is that I cannot achieve focus using the eyepiece projection method. Also I realized that I cannot do prime focus because my reflector does not have a thread, is this common in all the reflectors? I have tried the afocal method and it is the only thing that have worked. Is there anything I can try to achieve focus without using the afocal method?
Thank you.
AnswerAlex,
I could answer this -- but to be honest, I live in a city with lots of ambient light. So, I have almost zero personal experience with telescopes. I recomend that you ask Paul Wagner, or Tom Whiting. They are the two best Allexperts people when it comes to telescope-related questions. They each have TONS of experience, and everyone gives them high marks for their Allexperts assistance. Here are their websites:

I'm sorry I'm not helping you directly, but trust me, this is better.
Keep Looking Up!
