My First Time
Posted 02 December 2013 - 06:43 AM
I bought my first telescope - a used 8" with 12mm, 20mm, 40mm plossls. The first few days were spent examining the tripod and the various bits, and reading everything I could. I was conscious that if I tried to set it up without knowing enough, I'd damage something.
So on the first night that had gaps in the clouds, I put everything together in the back garden. I couldn't get the finder scope to align. Even with the screws farily tight, I couldn't point it far enough towards the right place. And so I couldn't align the telescope to use the fancy tracking or goto.
So I decided to just take a look at Jupiter. Despite all my reading, for some reason I had it in my mind that eyepieces worked like the eyepieces in binoculars; i.e. you twist them to focus. It took a few minutes to work out that the big knob on the back of the telescope isn't just for some type of obscure mirror calibration.
Unfortunately, because of where and when I set everything up, Jupiter was 10 degrees from the horizon, through the branches of a tree, past a street light and over some neighbours' roofs. Perhaps not ideal. Anyway, I found it using the 40mm eyepiece, and then worked down to 12mm. Wow! I could see Jupiter; two bands and three moons! And the fact that without tracking I could see it moving across the eyepiece was welcome confirmation that Galileo was in fact correct.
I since discovered that the finder scope bracket on the OTA needed adjustment. It's better now, I can't wait for another clear night! I must thank you all, this forum has been an invaluable source of information. I can't imagine how people managed it all before the Internet.

Do you have a 2x Barlow? It will work well with Plossls.

All that to say, enjoy it all! never let a cloudy day get you down.

I haven't got any barlows. I've been thinking about rebuilding the eyepiece set gradually, using Baader Hyperions. But I'll probably stick with what I have for now, until I get a better feel for what works well.
