I have one optec nextgen 0.7 reducer in as new condition (used once) for sale. It is suited to well corrected systems (apo's, meade ACF scopes) but please remember this is a reducer only not a flattener. I am selling it as it does not provide a field large enough for my chip (QHY 9 KAF 8300) and if you are considering buying it your chip must fit inside an 18mm imaging circle to gain maximum benifit. I will include a mounting adaptor suitable for a starlight express SXV H9 camera which can be used with other camera's (T thread) with similar backfocus. If your camera has a different backfocus you will need to buy another adaptor or I will machine this one to suit if you require a length shorter than 1.67 inches. This reducer would be ideal for someone using a meade ACF scope with DSI camera through to an ST10 or similar. Details can be found on the following links.
