I am also ordering Quark adapters with SCT thread to use it with SCT reducers (0.33x and 0,66x). If anyone is interested, let me know

Re: Quark and 2" eps
Do not use SCT reducers. They have a native (build-in) coma which cancels the coma in SCT. So, if to use it in QUARK the images will have a coma.Pablito wrote:I will be on the way soon

Also, QUARK has a flat field and SCT reducer does not, because it corrects the field curvature in SCT.
If to use a reducer, better to use a reducer for long focus refractors or for Celestron HD's - they are free of coma and field curvature.
BTW. 0.33x for SCT is especially bad.

Hi Valery. Thank you for this info. In fact, Quark will be tested also with SCT (with three front mounted mini ERFs). But trying it with refractor is veeery tempting
