Website that shows whats possible through different scopes

[M4lcs67]

Hi all,

There is a website out there that allows you to put your scope details in and it shows you what is viewable through your eyepiece, but I cannot remember what it's called. I'm sure I saved it to my favourites, but cannot find it.

Someone out there must know what I am talking about.

Thanks

How about CCD Calc: The New CCD Astronomy Home Page This shows DSO's/Sun/Moon through your scope (but is designed for imagers rather than visual observers). Just put in your details and it shows a field of view picture.

Or maybe this one: http://www.12dstring.me.uk/astro.htm with quite a few "FOV" type toys.

Sounds like 12dstring to me.

There's a "Switch to Visual" link in red on the right hand side.

Is it this?

How about the Ocular plug-in on Stellarium , you can load in all your scopes , eyepieces and camera chip details and see which combination suits the target best.

Have you looked at the Sky at Night web site ?

Weird thing here, I went to the site from S@N and my scope details transferred. Are they the same site with different skins?

On a personal note, I'd use 12 Dimensional lightly. It's a rough guide that may help but it will not show you what you will see through your eyepiece.

For example, take Saturn: to get anything near what I'm seeing in a 12mm EP through my scope, I have to plug in on the guide a Baader Ortho 5mm, and even then it comes over as being too small. In real life, if I use a 7mm, 6mm, or 5mm it blows this guide out of the water. And that's viewing from an inner city.

On the other hand, I certainly do not see the DSO's as the guide seems to suggest I would. Nothing like the detail or clarity.

Be it image size or viewing potential, in my case, at least, the site is not a help.

I agree. The seeing conditions, state of collimation of the scope, eyepiece quality and observer experience can all significantly impact (negatively and positively) the actual quality of view of both the planets and deep sky objects.

Seeing conditions (including light pollution) particularly can make a huge difference.

Simulators can't take the above factors into account so should be taken with a healthy "Pinch of salt" !

Could you post a link and how to do this ?

Thanks

This should help: Astronomy Shed UK Astronomy Forum • View topic - Stellarium Oculars

P.S: Thanks, John. I'm glad I'm not alone on this.

There's also this site which I find gives a good idea of what various objects really look like through a scope.
