That is astoundingly brilliant. Just what Ive needed to have a go with (the numbers). Its numbering and rotationablity will make working with bobs knobs childsplay.
Many, many thanks.
I had a very quick play with the first edition of your software and I think it showed a very, very slight miscollimation of my sct that led to slightly egg shaped stars in one corner. I think you program has fixed it but I need to take some shots to prove it. Thanks for such a great program. I admire your abilities.

For those who might be interested, I've included a PDF of the code. VB.NET programming is so easy (compared to where it was heading when windows first started - that stopped me programming!) the biggest problem is just finding the commands you need among all those available. Fortunately, the web and other resources are excellent help.

Used the second version. Just easy to use now and numbering the knobs helps determine which one to tweak. Just brilliant.

Brilliant! As a huge fan of Bahtinov Grabber, I've been looking for something like this for a while. Thanks!

It should appear in your start up menu under "All Programs".

Different versions of windows install to different directories, so without knowing what you have, if you can't find it in the Start Up Menu, search each hard drive you have (starting with C: drive) for the program name "AlsCollimationAid" or part thereof. Once you find it, use explorer to go there and make a shortcut, and move it to the desktop.

Thanks David and Dave!

Al.

Brilliance at it's best.

Gents,

Simply brilliant, I too have purchased an RC8 scope and have struggled with collimation and I am certain this will assist greatly.

Perhaps this can be pinned in the software section for easy access in the future for people.

I can't thank you enough. Cheers and may you be blessed with clear skies

Anthony

Hi All,

Not wanting to look stupid, but i'm going to anyway. When using this tool with a defocused star on a RC scope, should i be adjusting the the primary or the secondary for the final collimation tweaks or should i be doing both ?

Rich.

Secondary for sure. I've had a couple of schmidt-cassegrains and the primary is not adjustable on them, but I'm not familiar with an RC.

Play with the secondary to start with, and see if you can get good collimation.

Rich, RC collimation is tricky, and there is a well thought through process of steps and some tools are required. For the RC08, it is also essential to have the GSO Collimation Ring, this is the one you need:

http://www.bintel.com.au/Accessories...oductview.aspx

There are several very good threads here on IIS on how to collimate RC08s, I suggest you read through them it will save you alot of frustration and you will get a good idea of what has to be done and in what order. Suffice to say it is more complicated than collimating a newt.

You can start by watching this series of three excellent utube videos on collimating the RC08:

Hi Glen,

I have spent a small fortune buying all the tools, i.e. a Howie glatter plus circular pattern attachment, i also bought a Tak collimating scope. i've also read all the posts and watched all the youtube video's.

But i've found that, all these tools will get you very close but not perfect, hence wanting to use Al's tool as a final star test.

So all i want to know know is that when i'm doing the star test with Al's tool, as i adjusting the primary, the secondary or both.

Just want to understand the process, before i attempt using it.

Cheers,
Rich.

If you've got to the star test point then adjust only the secondary, the rest should be fine if you've been through all the bench alignment, provded your camera sensor tilt is not a problem.
