I'm pleased to share a good news with you. Indeed, thanks to Partha Bagchi (https://www.partha.com/) we are now able to provide you an .app file for OS X users.
This is a good improvement because no Homebrew or Xcode are needed anymore. Also !! the app is 10% faster for stacking.
You can download the app here.

Hi once again...
After spending a year with the mount i built i managed to gather some info about go to systems.
I am in my final year of mechanical engineering and will be displaying the mount as my project....but will b dding a go to system to it.
I will b getting help from the information technology team to programme the mount.
What i learnt is that you can control the telescope motion through stellarium using a raspberry pi microprocessor, a bluetooth dongle and potentiometers for motion sensing. I seen this video on youtube and will share tge link...if someone could rell me if this same setup would work on an equitorial mount??? For example...can the alt and az co ordinates be swapd with tge co ordinates of RA abd DEC...???
You can find the video on youtube...by searching
Telescope + raspberry pi + stellarium =itelescope
I've always wondered how magnification is achieved with a camera connected to a telescope, given that whenever I see pictures of a telescope and dslr or dedicated camera setup, there's never an eyepiece to magnify the image. How do you get a closeup image without a short focal length eyepiece?
Update 16th June:
I could not wait to tell people that I was just notified that my image of Omega Centauri will be published as a future NASA's Astronomy Picture of the Day ( APOD ) - my first ever
I will update the thread when they publish.
A deep look at Omega Centauri ( NGC 5139 )
This image is an attempt to look deeply into the the Omega Centauri globular cluster by using HDR techniques to record as many faint stars as I can whilst retaining colour and detail in the bright stars, including at the core ...
Reprocessed to bring out more faint stars and to produce a smother transition between brightness levels.

For sale 1000D camera modified for astronomy, the IR filter has been removed to allow the important red emission nebula to come through.
This camera has a very low shutter count of 4654 (at this time), and is in very good condition but has a light surface scratch on the LCD (see pic), which doesnt impact its performance and isnt visable when on. comes with a battery and charger, I don't have the original box, but will pack, very well. The price is £130 and includes delivery. This is for the camera body, no lens. Any questions please email me for guaranteed response........clear skys!
