So last night I was bored on a cloudy night and went down the rabbit hole on the internet.   SOMEWHERE I thought I saw a post where NINA allowed a custom horizon on the Sky Atlas.

 

This evening I googled and simply cannot find what I was looking for.   Does anyone know what I am talking about, and if so, is there a tutorial anywhere?

 

Thank you in advance!!!

It's in the nightly build.  People use apps like theodolite to generate the file and then you load it in NINA in options->general->astrometry->horizon file

 

Its a text file with azimuth and altitude pairs.

 

# Az Alt
0 14
5 69
55 77
90 70
105 35
115 10
120 24
135 25
145 30
205 20
230 23
235 14
240 14
265 33
285 33
350 20
360 14

Make sure the file ends in .hrz format and not .txt

There’s an iOS app called Observer Pro which, among other observation planning functionality, allows you to use your smartphone camera for real-time tracing of your horizon (tree lines, buildings, etc.). You can then export that CSV horizon file, as an email for example, from the app to use in NINA. All you need to do is rename the file to use a .hrz extension and replace the commas on the file with spaces. Works really well...

I only remember the horizon config because the NINA gang made me one for my obs

 

0 0

180 0

360 0

 

Not a tree or building within miles :D

 

we joked it should look like

I guess technically there may be 360 10 or so because of sliding roof... i'll give them that much lol

As I already had a home horizon in Stellarium I zoomed into the North roof level and clicked on a visible target at that horizon and recorded the alt/az of the target.  Revolved around plotting subtle or drastic changes in altitude until back at North (359).  Created the .hrz file and loaded into N.I.N.A, like 'Apollo' above, and hey presto.

Anyone know of an app that I can use with an Android phone to generate this file?

I couldn't get that to save photos at all on my Pixel II.  And it complains it is for an older android (which may be why). 

 

Any others?

Dioptra complains on mine as well, but I think having 20 or 30 points is enough and it does show the alt/az on screen so I am thinking Ill get my wife to help me for 15 min and just read 20 or 30 points out to her.

 

FWIW, I made my own horizon file by taking a 360 panorama and then figuring out a couple reference points for actuals (alt/az) and then calculating approximate altitudes for points on the panorama (approximated altitude and az degrees per pixel in the panorama).  It worked reasonably well actually but I think I can make it better.

Silly question but are the azimuths true or magnetic? Thanks,

I made a javascript app for this, but it only works on iPhone at the moment.

Does anyone know if it is possible to draw a ceiling? I mostly make my sessions from a balcony at my house and I think would be very helpfull to draw the limit of the sky altitude.

No, that would be a redefinition of the concept of a horizon.

 

A cursory search shows there's at least a half dozen videos describing custom horizon files on Youtube. The same file can be adapted for Stellarium and NINA and the process is identical.

 

If you're trying to visualize extents of targets, you can see the trajectory of a target in a number of places in NINA and altitude is easily derived as it is on the y-axis of the plot. If you're concerned about imaging your ceiling, you can use one of the loop conditions to image a target while it is below a specified elevation.

Patriot Astro had a very helpful tutorial here.  I was able to quickly build a file using Dipotra on Android.

OK, I see. That's what I usually do, but I thought would be way better to have a limit on the app, instead of calculating the altitude each time. Thanks for the quick response!

The latest non-beta version of NINA doesn't have the options->general->astrometry->horizon file input.  I was using a Youtube video that walked one through the process very well that showed the option, but my version  (1.10 HF3) doesn't seem to have it...or it's been moved.

It's in the beta, as apparently is all the good stuff.

I second the recommendation to go to Patriot Astro's you tube video, I used that to create my horizon.  I used my cell phone and a level app to get the view from my mount's perspective. I am a windows user and this worked fine for me.
