Edna , Renato's help here is spot on as usual , he is such a helpful guy , I applaud his words of wisdom .
Any way Edna , its very hard to describe colimation in words , its better to see it so try a 'Google' and type in ,
'youtube , collimating a newtonion telescope' and enjoy and learn from the 100's of clips posted there , its not hard if you take your time and remember ,, ' little movements ' .
Also there is no better thing than joining an astro society or club , is there one near you ? there are plenty of people that will help , but most of all , use and enjoy what you have and forget about getting more eyepieces , at least until you get more experience .
Brian.

What do you mean by eye relief for 4mm plossl is about 3mm?
Do you know which one should I buy for barlow lens? I opt for seben since it's affordable but others can be considered too. As long as it's not too expensive.
Regarding your question,I just bought my dobsonian around 2 months ago. So i'm not sure whether it's columated well but so far, everything seems to be find when I use it.
Sorry, I'm quite noob regarding astronomical equipments.  |
