PHD2 /apt

Recommended Posts

Hi guys 

getting totally confused none of it making sense anymore.

so when starting out ,roughly point north on mount and level it up with spirit level. 

Connect scope guide scope cables and then balance it all.

laptop and battery turn on and make sure mount main cam and guide cam all connected .

so back to mount/scope should the mount be at a angle so that the mounts polar scope has 0 at the top or weight at 6 o’clock and scope at 12 before u do pad on PHD2 have tried both ways and spent over an hour chasing stars into polar align box then redo pad and the box is not over star so have to readjust and this goes on and on . Not sure what’s happening I have polar aligned once with PHD2 perfectly and never again ( thinking now hot pixel). 

So I got fairly close so just thought I would see if apt would slew to item Ursa Major directly above my head and it ended up pointing west in to my house at that point I thought I would give up for a bit and have a cuppa .

any suggestions always welcome .? 

thanks Si

To polar align - start by aiming mount north and up towards Polaris (not level) the scale on mount is a rough guide to Polaris elevation (use your latitude from Google earth or a GPS) then start the PHD2 polar align feature.

Your mount should be looking north and up ?

Yeah I start pointing up and north but it seems to wrong from then on ?

Are we getting star alignment and polar alignment confused ... Polar alignment allows better tracking of the apparent star movement while star alignment allows accurate goto. Also have you set the correct time / location on your mount ? Can't see the equipment you use as on a mobile device.

Hi knobby

It's a synscan goto using laptop and eqdir so cord and lat time come from that dont they.as for star alignment cant find that anywhere on phd2 or apt.

The polar alignment routine in PhD2 is junk in my humble opinion. Just use the polar scope. If you want more accurate after that then the only thing that works for me in phd2 is drift alignment. But seriously just use the polar scope for now your doing 60second max exposures with guiding it's really not that critical. You have bigger fish to fry at the moment.

I dont have a frying pan big enough ?

+1 for sharpcap, it takes me about 5 minutes or less for the PA. I also made some markings on the floor after i did my polar alignment and when i place the mount over them it gets me very near. Last tine i did this i got it within a 6' error.

Do yourself a huge favour and shell out £10 for sharpcap. polar alignment is so much easier with that, you'll NEVER have to get on your knees and look through a poxy polar scope again. 

 

Just reading about sharpcap polar align not sure I've ever seen 15 stars in my fov.

32mm x120mm scope

4.83x3.63 mm chip size

Well was going well .

I cant plate solve anything .if on auto runs for 3 mins+ then I just stop it

Or if blind solve it cant find apm? What ever that is

ok probably need a longer exposure for more stars

Make sure you are feeding it the current scope position as a starting point for solving.

so second button down on point craft, says scope position.

Also make sure that you have given APT the focal length of the scope (650mm) and the pixel size 2.4um in the tools tab.
