Distance in degrees between Procyon & Aldebaran

[Scotlandyard 3]

Hello everyone,

I am having trouble with the settings of my Orion Intelliscope system. I am supposed to calibrate the intelliscope with 2 stars distant from at least 60 degrees.

 

Could someone tell me if the 2 stars I am using (Procyon & Aldebaran) are at least 60 degrees apart from eachother? Using the fist/finger way of measuring seems to me that they are just over 60 degrees.

I am having wrap errors of 3.4 so that is quite a lot. Maybe another issue is that my balcony is not totally flat.

Thanks for your confirmation.

Procyon is 46 degrees from Aldebaran

Algol would do the trick

If you download Stellarium you can measure the angular distance between any two objects. Stellarium:- http://www.stellarium.org/

BTW from my understanding of the Orion Inteliscope system your balcony not being level won't be an issue.

HTH and good luck.

So long as you initially carefully set the scope absolutely level ( on first set up, with a spirit level), my understanding is likewise that your observing surface (ground, decking, concrete whatever) is not a factor in getting a good low reading.  I've managed a couple of 0.0, but usually not! Good enough to get (for example) Uranus in my eyepiece, even if not centred.

Persevere - it's a good (nice and) simple system

thanks all for your ideas. I have Stellarium but I don't manage to measure the angles. Do I need a plug-in or something to enable that feature?

yes, you need to enable the plug in - they are in the settings section.
