Hi,

yes, that should be fine - if you search for a 'field of view' calculator online and put in the focal length of the guider and the sensor size, you should come out with a field of view somewhere in the 1.5-2 degree range (wider than for the standard 200mm focal length guiders)

cheers,

Robin

Just an update ,i was struggling to pa in sharcap using sharpcap PA ,i struggled to solve in the first part then when slewed 90 Deg ,failed ,so i changed to a 12mm cctv lens instead of the mini guide scope much easier solved easily ,once i had reverted back to the miniguide scope i rechecked PA this time no problem solving i assume this is because the FOV is smaller using the 130mm FL of the miniguide scope ,so if you do use the miniguide scope you really need to be close to PA for it to work ,as my mount is on a pier i should be able to use the mini guidescope from now on but if you struggle try a 12mm cctv lens £5 ish off ebay, on qhy5l-11, you need the 5mm CS mount not the c mount , i had to shim it approx 2mm making it approx 7mm to reach infinity focus
hope this may be of help to someone .
