Need help with Fov...

[SIDO]

Took this stack under high cloud last night after hacking together a new finder for my static eeva rig out of a 6x30 Celestron Ler finderscope objective a 25mm binocular objective for use as a reducer and an infra red blocking filter, should be 4.6 x 2.6° but not sure I couldent see hardly any stars visible with the high cloud and just took the stack blind on a camera tripod outside while sitting in my kitchen as the low temps last night were more like winter. So target area unknown to me/would like to know. Field of view unknown/would also like to know.

The original image is 1936x1096 and because its a static livestack png the crop removed the under exposed overlap leaving 1655x1018, I did the crop and a quick edit on my phone to help bring the details for identifcation purposes.

My system for eeva is static so just like manual visual observing I need a good magnified finder as the laser often only gets me close and this should speed things up. It can also be a fair eeva wide field set up I am discovering and already thinking I could start a stack on it as soon as a target is located then while busy making ajustments to the main scope camera I can toggle back and have a look after starting the main scope stacking application.

Any help would be great, this is all quite new to me, I know I've chosen methods that are uncommon so please bear with me here.

You can use nova.astrometry.net to do some blind plate solving and check the target, scale and FOV of your setup. I uploaded your image and here are the results http://nova.astrometry.net/user_images/2836462#annotated
