I have an 11mm Nagler Type 6 eyepiece that is brand new. Tried out during the Mersing trip. It is an excellent eyepiece with 82 degree FOV and excellent correction even on fast telescopes. Even better still it is very light and small in size, small with a punch. However, I have realised that my own eye astigmatism is slightly evident on this eyepiece when it is operating at a f/5 scope (giving exit pupil of 2.2mm) and hence I am looking for someone who is willing to buy this eyepiece at S$455 which is calculated from $280 usd x 1.63 exchange rate. This is cheaper than I bought at an exchange rate of 1.69 and there isn't the shipping cost. Also, TV has increased the eyepiece price up $10 usd for all their eyepieces. Note that Type 6 Naglers (has eye relief of 13mm) is meant for people who do not wear specs when they observe and it would be recommended (from my experience) that your astigmatism be 75 and below. I think mine is around 100 to 125 astigmatism.
