Jupiter and Saturn will form the first "double planet" in 800 years

Charles,
Sorry I found this thread too late for Jupiter/Saturn conjunction, but I recommend to watch this https://www.youtube.co​m/watch?v=eyAPIRbUs9I to setup your custom equipment in Stellarium. It is so useful to do this to see what you get into a frame of a camera with different lenses (you can set zoom lens with different focal points as separate lens - just name it like Sigma 150, Sigma 400 and so on). I have done it with my cams, lenses and telescope and now I can see what fits in camera frame with different lenses and telescope when I plan a shooting session and not guess if I get all object in the frame.

Hi Slagrim,

Do I add a camera lens as an eye piece then? The author of the video does not clarify that so I understand it anyway.

Thank you

Use tab "Sensors" to set your camera. Under this tab there is a list of some cameras to choose. Just click on your camera to highlight it and click on arrow pointing up (on the bottom between Add and Delete) to move it on top of the list. It will be convenient later to switch cameras if you have a few. If you will not find your camera in the list, find specifications of your camera in manual booklet or Google it, click "Add" button and on left side type the name of your camera, resolution X and Y in pixels and camera sensor dimension (for example: Canon 90D has resolution X = 6960, Y = 4640, chip width is 22.50 mm, chip height is 15.00mm). That is all in Sensors tab for now. Next click Telescopes tab. Here you will find some telescopes and lenses to choose just like in Sensors tab. If non of yours, again, click on "Add" and fill the fields on the left. For example I did for my Sigma 150-600mm zoom lens: name Sigma 150, Focal length = 150, Diameter = 95.00; click "Add" again, fill "Name" text box: Sigma 200, Focal length = 200.00, Diameter = 95.00 (always same with the same lens). Do it for any focal length of your lens as you wish. All entries will be saved on the left. Move them up for convenience. Now you can close this window by clicking the wrench and all entries will be automatically saved. Click on second icon (wrench area, see the picture). First you see Sensor #.. which means sensor in your camera. Clicking left/right arrows you go through the list of cameras saved in Stellarium. Second "Telescope #...". Here is your lens (it plays a role of telescope). Clicking left/right arrows you choosing your lens with needed focal length you going to set. Third choice "Lens" leave at none. This applies to additional corrective lenses like focal reducers, focal extenders and etc. Now you see the rectangular frame. Drag the sky object into the frame and you will see exactly what will fit in the camera! Clicking left/right arrows by "Telescope" you changing Sigma's focal length and see what field of view you have. If you do not see the frame - zoom in the sky by turning mouse wheel.
Hope it will help you.

Charles,
As soon as you set camera and lenses in Stellarium, now you can add Sigma Teleconverter. Again click wrench in Stellarium and choose tab "Lenses". Click "Add" and on right side click inside "Name" text box and change name like: Sigma TC-2X. Inside "Multiplier" text box put 2.000 (see Pics). Click wrench and click second icon which called "Image Sensor Frame". You will see how much Sigma TC affecting on field of view.
Happy New year and clear skies.

Thanks Slagrim .. I use stellarium mainly as a 'point and go'' tool, but I've never really explored it, this helps with where to go next.

Thank you for this. I REALLY appreciate you took the time to do this work for me. I know it took you you awhile to type this out for me.
I did most of this a couple of nights ago.

For my Sigma 150-600C lens I did 150, 200, 300, 400, 500 and 600. I also did 840 and 1200 for my two TC's not knowing you were going to add "Part 2"

Is there any difference doing what I did vs. the way you showed me in Part 2? Does the way I did it effect the how Stellarium works?

I have had company here all this week so I have not had time to actually try any of this in Stellarium just yet.

Again I really do appreciate what you did here for me!

You very welcome Charles,
Just wanted to clarify what lenses, sensors and telescopes meant in Stellarium. Sometimes it is confusing.
Does it have any difference what you've done? Not at all. Simply good to have separate TS in record to try it out with different lenses/telescopes to see what a difference it would be.

I am guessing you had around 2 to 2.5 hours total time to put all that together, maybe 3 hours.

I do THANK YOU again!

Slagrim,

I just tried for my first time to load the camera and lens into Stellarium, but as I change the focal length from one to another I do not see any changes in my viewing.

I first selected the moon, then I click on the wrench, then I click on my 90D camera body, then I click on one of the lenses. When I then change to a different focal length I see no difference.

How do I load the camera body and then the "telescope" into Stellarium??

You do not need click wrench anymore. Click second round icon (see last picture) and immediately you get a view as on the same picture. Look at the arrows on both sides of words Sensor #.., Telescope #.., Lens #.. . You can click on this arrows to change Sensor (camera), Telescope (Camera lens), Lens (TC or without it). After each click on the arrow (right or left) Stellarium recalculates field of view and you will see different scale of the object. You do not need to re enter camera or/and lens data anymore. Stellarium remembers all entries you have done previously. In other words wrench needed only when you recording your equipment into Stellarium. In second icon you just pulling up saved data of you gear. This is quite convenient to see how scale is changing at different cams and lenses combinations.

Thank you! I got it figured out! Well partially... I do see the moon enlarging or getting smaller changing the lens settings, but do you have any idea why I am seeing a reddish hue in the image while I am doing this?

Thank you again Slagrim!!

You welcome Charles,
This represents Menu settings on lower menu bar. By default it is hidden. Move mouse to the bottom and menu pops up. Point cursor over any button and on left side you will see what it represents. In your case it represents Atmosphere (simulation of atmospheric influence on visibility). You can click on any to turn it ON or OFF. Move cursor to the left to see more Menus. Same as on the bottom, place cursor over and read what it is. For example clicking on clock initiates Time window. Clicking on small arrows (see second picture) you can move sky view to the future (how it will look in few hours or even in few years) or to the past. I use this feature all the time to plan photo session to make sure my point of interest will not be hidden behind house roofs or trees and find better place for tripod with clear view for most time of a night. Do not hesitate to try out any feature of Stellarium. It is very powerful tool to help yourself in astrophotography.
