ANTLIA TRIBAND II RGB ULTRA FILTER 2"

Perfect for the Celestron Origin

The fast F2 optics of the Celestron Origin don't always play well with filters. The Antlia Triband II is the exception. It does an excellent job of LP filtering in my Bortle 7 light soaked backyard and provides a very well balanced colour output. Other fast filters tend to be more biased to the reddish Ha and Sii signals at the expense of the Oiii signal. This little beauty is seldom off my Celestron Origin. Trifid Nebula, 44 x 30 sec 500 ISO

Nice filter for general imaging.

A great filter that works well for all objects. Great solid magnetic seal case. Highly recommended for all general imaging.

Great filter

Performance of this filter on the RASA 8 is very good, as good as the Celestron branded LPF but a fraction of the cost. I saw no gradient in the 300 sec subs taken in a bottle 4 sky looking towards Hobart. Results look very promising and I am glad I made the decision to purchase this filter.
