My best purchase from the Practical Astronomy Show. These binoviewers differ from other makes in that they do not require any extra in-focus. You never see these on sale….but this one was around £100 off new price! I have tried binoviewers before but the need to use a Barlow lens in order to obtain focus on my Newtonian telescopes has meant that they weren’t very practical. I decent read a review in one of the astronomy magazine about this binoviewers and the reviewer was so impressed he bought one!
I tried it today on my Orion 10″ Dobsonian telescope. In order to get focus, I had to use an extension tube plus my Tele Vue Paracorr – the latter has a long tube and I can pull it out quite a distance to act as an extension tube. All of this suggests that I will easily obtain focus on the night sky.
At the Practical Astronomy Show I purchased a pair of discounted APM ultra flat field 18mm 65 AFOV eyepiece and I already had a pair on Tele Vue Nagler 7mm eyepiece.
The view of the trees at the bottom of the garden was amazing! This the first time I have ever had a proper binocular view through a telescope without any sense of strain on my eyes! Both pairs of eyepiece worked well. I can’t wait to get out under the night sky. Only problem is this could work out really expensive on eyepiece with my having to buy a second one to accompany some of those I already have…..
Always worth having a bag of eyepiece caps so if you see any being sold cheap I recommend you purchase some spares in 1.25 inch and 2 inch varieties for both ends of the eyepiece. Below is my bag – the cheap 18mm eyepiece did not come with caps so good job I had some spare.
The attachments I used to obtain focus – this was opposite of in focus = out focus – as I was focusing on the trees at the bottom of my garden which are closer than infinity.
The Tele Vue Paracorr is one of my best ever purchases – so useful!
