Well nicely done indeed, and all that info left me a bit bamboozled, however i am sure you know what it all means, well done.

Leon

PS, maybe it should be in the deep space section

[leon]

Sorry, gee i am getting old it is already in deep space talk about stupid

That is a nice field of view with good detail of the objects captured Diego

[Placidus (Mike and Trish)]

A very pleasing image. Lovely.

[Andy01 (Andy)]

Nice wide field there mate, reckon it’s worth going super deep on that one

[billdan (Bill)]

Well done Diego, it gives me a sense of perspective of the Orion region. I noticed you didn't use the Blue filter, only the Green ( probably don't need Red). I guess OIII was used as blue.

[gregbradley]

A lovely vista.

[allan gould]

Great image and excellent information of your imaging system. That's much appreciated

[SimmoW (SIMON)]

Yeah thats a great test Diego! Ive asked elsewhere, what focal length did you use? Looks like a mosaic!

[diegocolonnello (Diego)]

55mm, no mosaic, that is a wide as i could go with the lens
