Hutech/Canon DSLR FAQ Chart

I’m sure more people are enjoying a new 6D these days. Yes, this is the wonderful camera for astro use.

LR_6D_BODY_FRONT_CLFollowing comparison chart is made based on the common questions from customers.

comparison021413 Our option T is the method used from the beginning. The original color correction filter used to be replaced with IDAS UV/IR blocking. However,

1) Less number of filters are always better to minimize internal reflections

2) Recent Canon-made UV/IR blocking filter has the superior optical quality and the response curve to fully meet astro requirements.

So we have decided to use Canon filter as UV/IR blocking. In fact, current option T looks making each star edge cleaner than the previous.
