Mounting 6200 tilt adapter directly to 7 pos. 2" EFW

Post by valrayco » Wed Feb 19, 2020 2:43 am

Is there an adapter plate available to mount the tilt adapter directly to the front of the 7 pos 2" EFW without the OAG? I currently have the 6200 bolted to the EFW, but there is a slight tilt to the CCD that I can't adjust out because I can't mount the tilt adapter directly to the front of the filter wheel. I do not have the OAG. I am trying to reduce the camea back focus to the filters as much as possible.

I have not been able to find a M54 male to male adapter to mount the camera with tilt adapter to the back of the EFW. Does ZWO make such an adapter?

You can try this setting:
6200(12.5mm)+sensor tilter(5mm)+2" EFW(20mm)+M54-M48+16.5mm M48-M42 adapter, you will get a total back focus of 54mm, but it is difficult to adjust the sensor tilt.

Katherine:

When reducing the image train diameter to 42mm, will there be significant image vignetting? The image chip is about 44mm diag. and I am using an F4 refractor which will probably make matters worse.

You mention attaching the camera w/ tilter to the back of the EFW, Do you sell a 54mm male to male adapter? As both camera and EFW have female fittings. I don't know why ZWO didn't make a male threaded output on the camera similar to most of the other cameras ZWO makes.

thanks

There will be vignetting.:(

Sorry we do not have this M54-M54 male adapter.
