    Celestron Hummgbird mini scope

    Confirmed recently that astro eyepieces can be used with this scope. I tried two eyepieces (20 mm plossl and 9 mm TMB planetary). The view through the planetary was very good, but the plossl could not reach infinity focus. Smyth lens on the planetary, maybe? Rmel66.

    Fixed eyepieces for Helios Filedmaster ED60

    When using the astro eyepiece in the holder, you can modify the eyepiece by screwing the barlow element of a shorty barlow directly into the eyepiece barrel and then placing in the holder. In many cases this allows for achievement of infinity focus. rmel66.

    Compact spotter

    What is the diameter/thread pitch of the external thread? I checked on my scope and the specs are ~44mm x 1. rmel66.

    Compact spotter

    The eyepiece does not go inside. The long focal travel of the C70 Catadioptric scope allows for an adapter that screws on to the external thread shown in the photo without compromising the infinity focus with an astro eyepiece. With the Helios, the adapter would probably not allow for infinity...

    Is the eyepiece hole as shown in the picture? This is of my Celestron C70 with the eyepiece adapter removed. rmel66.

    Russian scope built like a tank. Bought a non-zoom version for my nephew a few years back. As said optics surprisingly good. Rmel66.

    Cheap draw scope opinions please

    The Scout Yukon is readily available. I had one and used the objective to make a very sharp 50mm spotting scope that uses 1.25" eyepieces. http://main.yukonopticsglobal.com/product-overview-scout-30x50.html
