Hi SGL,

is there any plugin or setting that can (more) accurately depict views through an eyepiece?

I'm aware of the oculars, but what I'm after is the shimmer of the planets, dimming of DSOs when using smaller scopes, planetary detail dependent on telescope size etc.

Thanks

The challenge is that the some of the factors you list are so variable, locale to locale, hour to hour etc, that I can't see how they could be factored in for locations in the world, which the software covers :dontknow:

They do cater for atmospheric extinction which happens as an object moves towards the horizon and they cater approximately for the amount of daylight still in the sky. You can set your altitude about sea level. That's probably about as far as such a tool can go.

Also, an experienced eye will see more detail than an inexperienced one with the same scope. A dark adapted eye will go deeper than one that isn't. Where would you set the benchmarks ?

I see Stellarium, Cartes du Ciel etc as primarily tools to locate targets. I think what you are looking for is more of a view simulator ?

visual simulator, yes from my point of view and possibly the op’s. In my case it’s so my eagerness doesn’t sweep straight past things. (I need to look harder).

In doing presentations to my astro society, I've tried to produce simulations of what some objects look like though the eyepiece. With the fainter ones, by the time you have toned down the contrast to get it close to how it actually looks, the target has practically vanished when you project the image onto the larger screen, even with the lights turned off !

Maybe less coffee on view sessions will help me slow down 👁👁

Don't mean to be controversial here.....but if you could simulate the view exactly, what would be the point of observing?

It’s more a point of having some idea of the limits from scope/eyepieces from my point of view.

Maybe for someone who has decades of experience this is not necessary, however due to my long shifts - a tired eyes observation is unfortunately the best I can fit in.
Having the degree of faintness of objects I’m looking for would help me find things as I use a manual Az/alt setup with no Automatic tracking etc. It’s all about achieving my goal with my equipment if that makes any sense.

Dantooine & greg110902 - I have found this site useful https://www.stelvision.com/en/telescope-simulator/

As John has already mentioned its possible in Stellarium but configuring all the parameters is going to be tricky 🙂

 

That's a very useful site. Well worth reading the pop up info you get when you click on ? is this simulator realistic ?

What an individual actually sees may well vary to some extent from the simulation images. Light pollution, for example, can cause galaxies and nebulae, even bright ones, to become practically invisible while under a dark sky they stand out like a sore thumb !

But it is a useful approximation.

John,

you are an oracle.

      Since I live in a flat I do most of my imaging from my balcony... I purposely choose a top floor because of my astrophotography passion in order to have a decent field of view, but my balcony has walls on one side and on top. 
      So I decided to bring to Stellarium my own landscape and my FOV so I can know exactly which targets are on sight and at what time. 
      I have done some reading and watch videos but I still have a couple of questions before I begin and hopefully some people from here could help! 
      a) how should I take my photo... Me standing straight levelled with horizon or placing my camera on a tripod and place it like a telescope looking up in the sky towards North? 
      b) the famous cardinal points and the line angle_rotatez= in the ini file... Is there a secret of finding this number easy in order to match cardinal points to my photo or the only way is by trial and error....? 
      Thanks for reading
      Nikolas.
