Quark to sensor spacing, does it matter?

I have a 90mm f/7 refractor and a Daystar Quark (with the built-in 4.2X barlow) and I'm going to start doing some solar imaging.

 

For DSOs, I use a FF/FR which specifies 56mm as the 'ideal' spacing between the FF/FR and the camera sensor.

 

Is there a similar concept when it comes to the Quark?  Is there an 'ideal' spacing between the Quark's body and an imaging sensor I should try to achieve?

 

Thanks in advance..

Are there any Quark imagers who can answer this?

 

Should I try to achieve a particular Quark -> imaging sensor spacing?

 

Does the spacing affect image scale, ability to focus, image quality, etc.?

 

I'd like to have some idea if it matters.  And if so, how, before I start acquiring any adapters I'll need.

As odd as it may appear, few in this forum get deep into solar imaging... this is largely a lunar and planetary forum. Eyecrazy.gif

 

Your question is best asked in the Solar Observing & Imaging forum. That forum started as observing only, but in time virtually all the solar imagers tended to post there, and CN eventually changed the forum name to reflect that.

Thank you.  I didn't realize there was a solar-specific forum.  I just assumed 'solar system' would cover it all...  :)  I'll post there.
