I understand 10x50 is good for looking at the stars, would these be suitable, my other half wants to look at the moon.

Yes, 10x50 is recommended for looking at the night sky.

The Helios Fieldmaster would be ideal binoculars for looking at the moon and for getting a sense of direction (finding out where things are) when looking at the night sky.

I was looking for a pair of binocualrs for plane spotting (reading serials off the back of planes) and was wondering if this size would be ok or if another size would be better and if so could you point me in the right direction.

It all depends upon distance.

If you can get fairly close to the aircraft, then 10x50 will be ideal - here in Lincolnshire we have lots of RAF bases, RAF Waddington has a viewing area at the end of the runway and the aircraft are parked fairly close as well, in this case 10x50 would suit very well.

If you are using them at commercial airports, where the aircraft can be quite some distance from the viewing areas, I would suggest more magnification, probably as high as 16x50. Although even this may not be enough, a lot of our customers have started with binoculars around 10x magnification, tried higher magnifications like 16x or even 20x and then progressed to using a spotting scope (a lot of avaition enthusiasts are using the Visionary Airman wich goes upto 45x magnification, but does require a tripod).

If you want to get the number whilst the aircraft is in flight, I would generally say this is impossible, except for landing and takeoff. Commercial aircraft at 30,000 feet arejust too far away, I took some pictures through a spotting scope of an aircraft at altitude and whilst you could probably find out the number by identifing the aircraft, airline, the time and direction of the flight, the number cannot be seen.

For seeing the number on military aircraft in flight, again it would depend upon distance, speed etc. Around these parts, we have low altitude AWACS aircraft flying around fairly slowly as well as C130 Hercules and at the other end of the spectrum, we regularly see the Red Arrows.

Please could you tell me the approximate IPD range for this binocular?
Many thanks

The manufacturers do not list the Inter Pupillary Distance in their specification.

We do not have the equipment to accurately measure it, but it is roughly 57-74mm
