Re: INDI or ASCOM Alpaca?

Ray Gralak

Hi Dale,

Okay great. I am looking forward to reading your blog after you get a chance to post it.

And yes, I think there is a possibility of supporting both INDI and Alpaca. The dilemma is that Alpaca's driver interface is not
available. Thus, even if an A-P Alpaca driver is created other manufacturers might not want to create new drivers until ASCOM can
create a driver framework. Then after a critical mass of Alpaca drivers is reached it might then make sense for application
developers to create non-Windows applications for Alpaca.

Best regards,

Hi Ray, thanks for bringing these subjects up. There are a lot of aspects to each.

Foremost, I don't see this as an exclusive OR choice between the two, and I ask that everyone try to mentally
maneuver away from the "it has to be one or the other, and never both" mindset. There's no reason why ASCOM
(in any flavor) and INDI frameworks can't enjoy parity insofar as A-P hardware support goes. There's plenty of
need and room for both across a plethora of OSes, architectures, and programming languages.

This topic is of great interest to me personally and there is a lot of technical and philosophical ground to cover, but
it finds me busy packing on the eve of a trip so I'm unable to contribute to it in-depth at this moment. In the quiet
moments on the plane I'll put my thoughts on my personal blog, as I find it a better venue than email to lay things

Hello all,

Of those users wishing for a non-Windows support for your mount, which platform would you prefer Astro-
Physics to devote resources?

INDI or ASCOM Alpaca?

INDI has been around for some time and runs on LINUX and MAC OSX and Windows. ASCOM Alpaca is still in
the early stages of development. There are no significant applications that work on LINUX or MACs, and there
may not be for some time.

However, ASCOM Alpaca is modular as opposed to INDI's monolithic design. Once drivers are available Alpaca
devices can be standalone (over the network or wifi) or on another computer. I believe INDI only works on the
computer it is running unless the device has a network interface.

There may be other advantages or disadvantages to INDI or ASCOM Alpaca. Please contribute your
knowledge or preferences if you are interested in this topic.
