    Default Explore Scientific 68 degree 16 mm first impression



    Santa brought me ES68 16mm this year. Tiny EP in big ES box . Here is how my ES68 set looks now



    I liked ES68 20 and 24mm so much that I decided to try 16mm. It did not disappoint . I managed only one observing session so far, but I can tell it is very sharp. Just from one session it feels as sharp as 15mm PLossl and somewhat sharper than ES82 14mm.

    I was concerned about tight eye relief of ES68 16mm, but it is not bad. In fact ES82 14mm (15mm ER listed) feels tighter than ES68 16mm (11.8mm ER listed). First I did not understand why but after taking this photo of my EPs in 15mm range it became clear.



    Notice how deep top lens is set in ES82 14mm (~1cm)? While in ES68 16mm it is almost as flat as in 15mm Plossl? So plenty of ER is lost in ES82 due to that. Did I mention how tiny 16mm is? . Close to Plossl size.

    Intrigued by how deep is the top lens in ES82 14mm (how I did not notice before?...) I did a group shot of my ES82 EPs.



    But even between ES82s 14mm stands apart as far as how deep is the top lens set. 11mm has the shallowest offset and it is considered to be the best in the series. Coincidence?

    I plan to do more comparisons, but so far 16mm looks great. Small, light and sharp, the way I like them

    Here is how my observing EP case looks now.



    I think I am all set, but surely you heard it before

    Nice! Congrats on the new glass! Wow, it is small, but mighty nice looking.

    I've never noticed that on the 14mm before. Huh. The 82° 24mm and the 30mm have a rather deep well too.

    So, what is the optical difference between the 82-degree and the 68-degree series (apart from apparent FOV)? I have the 82-degree 8.8mm and love it.
