Excellent image. Great detail in the nebula and nice tight stars. Just curious. Which version of the W.O. .8x reducer are you using? I have the 0.8x reducer/flattener II which seems to work very well with my 80mm scope.
Your stars are perfect right out to the very edge.

Herb, Thanks. I use the WO 0.8x FR/FF WFLAT2. I'm not 100% pleased with its flattening and have been experimenting with spacers to get the focal plane-to-optics distance correct. The above image had additional edge flattening done via Photoshop.
