Trouble 3 Star aligning My Celestron CPC 8 inch

Hi


I have an issue re sky aligning my scope (CPC Celestron 8 inch) could anyone assist me. Im trying to put in the coordinates manually (150 07 60.00 East, -36 05 60.00 South) and for some reason it wont respond when I press Enter after i key in the numbers. My GPS doesnt seem to be working. Hope its OK me posting here but Ive waited so long for a clear sky since my scope arrived

Are you entering your position in degrees, minutes, and seconds, or in decimal format, and which does your GPS require? Most GOTO mounts
will only accept it in one of the two formats.

I was entering degrees, minutes, and seconds. Not decimal format (I believe)

The Celestron site says it uses degrees, minutes, and seconds BUT the celestron page was last updated in 2010 & in another site (StaryNight) they said they used decimal. You think Celestron would keep their pages updated more regularly

The handbook that came with your mount should show the required format.
Either way, just try both formats, and then at least you will know if that is the problem solved or not.

Hi Claude,
potentially I see two problems.

you wouldn't normally enter a minus sign if you are also entering "South"

and 60 seconds does not compute.
That is an extra minute.

Maybe this may help

It's been a long time since I ran a CPC, so memory is a little foggy on the details.
Regards
Allan

Also,
Are you sure the built in GPS is not working?
Presumably this means you bought it second hand.
So it may be an older model, which may bring in other possibilities.

But, in relation to buying a second hand CPC, the manual says:

If your CPC is transported over a long
distance it may take as long
as one hour to establish a satellite link
from its new location. Observers wishing
to travel long distances with their
telescope are advised to turn on their
telescope in advance to allow the GPS to
acquire the necessary data.

Additionally, the GPS could be set to off.
This is in the Utilities sub menu.

Thanks Allan. I think you hit the nail on the head on all 3 counts. You're right I think now the GPS is working (its a new new shiny sparkling scope and Im getting attached already) My big mistake (stupid I know) is that I was so busy fretting looking for the minus key that I didnt realise that as I was speeding through confirming the data the scope was throwing at me I also confirmed North when I should have toggled down to South. Im embarrassed but its best to be up front about it (I think?). The 60s I got from a site on the net that prompts you to type in your town/city etc and they'll tell you your co-ordinates. Ive got better more reliable co-ordinates now but I dont think Ill need them now and just let the GPS do its work.

So Im feeling pretty optimistic now that I will get the scope up and running tonight & it looks like it will be lovely clear skys AND of course the added bonus of the meteor shower.

Thank you for taking the trouble to advise me. It was very kind of you & is much appreciated.


Regards


Claude

Hi all.

Been doing Milky Way & wide field astrophotography for a while now but got my first telescope in April and looking forward to the challenges and adventures it brings. Hoping for clear skies & dark nights.


Cheers
