Title: Finally
Post by: mickw on Apr 04, 2013, 09:09:08
Finally started (finding it all and) installing all the astro software on the replacement W7 laptop.

Starry Night, Ascom, APT 1.93 (need to update that) and other assorted bits and bobs so far
Just downloaded new QHY drivers which will hopefully work first time unlike the original guessing game.

So be prepared for a barrage of questions about settings - which I had the foresight to never make a note of  :oops:

Aaarrrgghhhhhhh

I'll get the question out of the way first -
I can't remember if the Guide cable form the QHY connects the mount or the guiding is just controlled via the USB and EQMod
Thanks

This is doing my head in  :-?
Most of control software now installed twice before finding a duff USB extension lead and loose power connector  :wall:

EQmod being a git, successful Test Connect but doesn't Register despite being able to control mount from the control panel and Starry Night  :-?

QHY Video doesn't work but PHD appears to - not too fussed about video but it would have been useful to help check things out.

APT seems very happy and links to PHD, TemperHum and even takes pictures.

I'll pull it all apart and start again later.

Oh dear - what a tiswas !

Either way will work Mick but I use the USB method since the scope is controlled through a PC anyway and it cuts out one cable.

Mick, I seem to recall you telling Mark ages ago that the ST4 cable from the QHY connects directly to the mount, this is the way that I do it too.  So I guess this is what you used to do.  I was just about to buy a QHY5 at the time and the reason I remember is that I found that bit of info rather enlightening.

Thanks Robert, I wondered why I'd coiled up the cable so neatly  :roll:

I've also found my old setup notes  :)  
Seems I did the Test Connect and Register backwards in EQMod  :oops:

Thanks Carole, I know my setup went through a few evolutions and suspect the latest one was without the cable

If you are using EQ-MOD then you don't need the ST4 cable, just the USB.

Thanks Mike, starting to make sense now, I was a late starter with EQMod

About to start again  :)

Woohoo

It's alive  :D

Things have also changed with the turn on/start up order - Odd - Starry Night now livens up EQmod - I'm sure it never did

So it's Plug everything in and turn them on, then start SN, PHD then APT.
The powered hub with the iffy power lead works OK unpowered - Result - still need to sort out USB extension though
All software and hardware seem to speaking the same language.

Only scary moment today was a crunchy, rattling sound coming from the mount when slewing and then it stopped slewing - The power pack battery was nearly flat  :roll:

Still need to sort out the settings in PHD and EQmod, the only thing I remember about EQmod was to change something to 5 or possibly .5 - I think it was in the pulse guide section.
Any help for both would be appreciated - screen prints of the settings would be nice  :kiss:

I don't think there's a rush, just got to wait for the rain, gales and clouds to disappear  :!

Any reason why you are using Starry Night and not Carte Du Ceil?

What is your guide camera?

I've had SN for ages and personally find it easier to navigate than CdC.

Guider is QHY5

Your PHD settings will probably be similar to mine then. I'l let you know what they are when I get home and you can use them as a starting point at least.

Mick, you should use EQMOD_Run to start EQMOD before any other software, that way a crash from PHD or SN won't disconnect the mount. You can copy the menu shortcut to the desktop.

BTW APT is now in version 2.20

Good point but do you mean EQAscom_run ?
I used to start it all off with "Toolbox" which seemed to fire up the  _run file but got lazy when I found SN did it for me
I'll give it a try later.

My "subscription" to APT has expired and I couldn't be bothered to update until I'd got myself sorted.  When everything functions correctly I'll upgrade

You'll no doubt need to play around with them to suit your kit. I use a small 60mm finder scope as my guide camera so these settings suit that scope. I'm guessing you would use an 80mm guide scope or an OAG so you might need to play around with either the timing settings or the aggressiveness to suit your set-up.

I agree but at the moment the QHY is on the back of a 50mm guidscope so the settings shouldn't be out by too much

They will probably work then.

Sorted - possibly  8)

At last all the software seems to be working and talking amongst themselves, the hardware all seems to be operating correctly as well.
I'm just going outside to set for a proper test  :)

Oh hang on it's raining  :( :( :( :( :( :(
