cocoon nebula old Russian lens

[alacant]

Hi everyone

We converted our wide field setup from flimsy narrow dovetails to wide versions and added a steel bracket for right angles. The built-like-a-tank Tair-3s now holds at all angles;) This was an attempt to capture the dark nebula which extends west from the cocoon. Not sure If I've the correct orientation though. Do we have orientation for astrophotos I wonder?

It has a nice flat FOV. I think it was designed for medium format; there's no vignetting.

We tried to match the colour with that of the same target we took with a reflector but couldn't get it as FWOABW dreamy.

Anyway, thanks for looking and clear skies.

Orientation, mine are often upside down, nice shot.

I think that compared with an astronomical telescope, the lens would be flipped vertically, but judging by the angles an eq mount gets into over an hour or so, I think the angle humans interpret it as is constantly changing. Also, compared to our reflector image, it's flipped horizontally. And what about after a meridian flip? Ahhgghh!

I'm giving up.

I don't actually feel any of us care, I for sure never move the camera positions so the shots are at all angles as you say due to the EQ mount, at the moment though I am mainly shoot south so not so noticeable.

i agree with Alan, orientation does'nt matter as long as it's framed nicely and which you have done. a fine WF image
