Webcam fov

Posted my "first moon" pic the other day, but can anyone advise on how to get a wider fov. Advice much appreciated.

Cheers

You could use a focal reducer which screws on like a filter:

Antares Antares 1.25" focal reducer 0.5x

Thanks John,

Apparently my current fov is equivalent to 6mm, will a reducer affect my view visually?

Sully you might have a problem with a focal reducer on your newt.

I bought one for my 8 inch to try and solve the same issue.

When I fitted it I found I did not have enough inward travel on the focuser to get the image into focus.

Still all was not lost as I now have it fitted to my guide scope.

To get a wider field of view you need to create a mosaic of several images stitched together in Microsoft ICE. Take a look in the http://stargazerslounge.com/imaging-lunar/125523-2010-lunar-imaging-showcase.html. There are three images of mine towards to bottom of the page. The first two , Clavius and Copernicus are single AVIs, the third of Plato and the surrounding area is a mosaic of 6 AVIs stitched together in MICE. All three were imaged at the same focal length (3600mm) and the same equipment.

Focal reducers don't always work due to a lack of focuser travel.
