WO Megrez 72mm

Just purchased a WO Megrez 72mm scope with DDG and 0.8x FF. What an absolutely brilliant scope.
I originally thought that I would use it exclusively as a guide scope but it came with the DDG (Digital Display Guage) and I must say I originally thought this would be a gimmick, but its so damned accurate and useful I use it all the time. Focus is always spot on for guiding or imaging.
I also bought the 0.8mm FF type III and it just gives a flat field across the QHY8 chip which is a physically large chip. I have just finished a 3hr QHY8 shot of M42 to see what sort of dust is in the region and all I can say is there is a heap of it. Just have to process the image properly.
I went for this scope after Paul (1ponders) mentioned it at Astrofest, then I looked at some images he had done with his and I was convinced.
Goes so well with the 5" APO refractor.

It was an overseas buy but direct from WO. They had a special on a few units with the DDG at slightly less than here in Australia (for the same 72mm WITHOUT the DDG) and with free shipping. Could not pass it up.

Yeah Paul, I took a three hour shot of M42 with the flattener last night and was pleased to see sharp stars from corner to corner.Just processing it now. Its a sharp little scope. Very happy chappy.

Sounds better than the zenith 70 I had. I used it as a guider for ages and it worked fine but imaging through it was .. challenging ?

I see they have some M72s minus the DDG for only $400 or so posted. That seems like a good deal.... I couldn't see any with the DDG option....

No, the DDG option was only available for a short time and only two or three units. Luckily I managed to bag one of these unique units. I was surprised at the lack of colour and sharpness of the unit

I'm looking forward to seeing your results. I have one of these little scopes but have only used it for guiding. I was just thinking a couple of days ago about getting the same FF and imaging with it.

I have used a WO72 as my main imaging scope for over a Year now and I am very pleased with it. Very well built and it is also a great grab and go scope on an alt az mount. Very contrasty with a 27mm panoptic in it.
I use a skywatcher field flattener with mine. Its not focal reducer but it flattens out the field quite well for my DSLR and its was half the price of the WO reducers.

I got mine from Ian King in the UK. There are some reviews on astronomy forums.
