i know that Star Targ is software, but what is it, and how will it help me

with my endeavors as an amateur astronomer and a astrophotographer???

andy has a great video abt the new features, and the price is okey, however,

is this what i will use for drift alignment??

hey, you know, inquiring minds want to know these things..........

Craig, startarg is a simple program that helps you accomplish a drift alignment much faster and with a high degree of accuarcy. Best 20 astrobucks I've spent. I also use it to keep subsequent frames aligned. A little trick Eric suggested.

tim, tnx fer yer info........

i will be using a CCD (Meade DSI II) for my imaging, and not a DSLR.......
will nebulosity 2 be sufficient (spelling??) to work in my situation???
i'm still gathering up all my equip. and thoughts together.....
from the CSC for my area, wind and overcast has put a damper
on viewing, probably for the next few days... but, such as it may,
i'm getting excited abt the upcoming launch of Endeavor this SATURDAY....
seven astronauts on the shuttle to the ISS, which already has 6 aboard,
the total of 13 will be working in pretty cramped quarters.....
the only woman is Julie Payete from Canada. i think from the east side,
'cause she has a slight french accent. they all have such a joyous
smile on their faces.... wish i was goin' with 'em.......
probably the wrong section for this type of thread, but i
get excited when it comes to the possibility of going to
other far away places.....................................................kreigor

Hi Kriegor,

The quick answer to your question is: If your camera (of any kind) will put an image on your computer desktop, then StarTarg will appear on your desktop on top of that image. StarTarg's primary use is drift alignment. Instructions for using it as such is included in the program and can be accessed by the great big button labeled thus.

Not only is startarg easy to use... its the only thing i use now to do my drift alignments.
that is when i am not too lazy to do them!

If you haven't already purchased it... do yourself a favor and get it.
a very useful tool.

Andy,

I just used Star Targ 2.0 last night for the first time. I was a little shaky at first and it took me a while but, I could see the purpose of DA very clearly by actually doing it instead just reading about it. I think I understood your tutorial./ and or cheat notes in the actual program. But, there are a couple of questions I have :

1) Why is the additional movement of the mount in perspective to horizon needed after you get the Azmuth adjustments down? You are instructed to go to 20 degress above the eastern horzon and do the altitude adjustment.

2)Would it matter if you started and finished on the eastern horizon? (as you probably figured out that is what I did). I have read other papers on the net stating that a meridian-close star is all that is needed so why the equator proximity as well?

I used the 90 degree to the RA axis trick and I think it worked but can't be sure.

Thanks Andy or anyone who has completed DA and can answer. Appreciate it!

When you are monitoring a star on or near the meridian and you observe the star moving off of the crosshairs, this ONLY reveals a misalignment in the east-west direction. This is why you move to the star near the eastern horizon, because movement of the star off the crosshair while there will reveal ONLY misalignment in the north-south direction.

Accurate alignment requires adjustments in both directions. Those who do only one will certainly be accurate enough for visual astronomy, but for those of us who do astrophotography, you must be as accurate as possible.

Thanks for the quick reply. I errored in describing posts on the net, I have a bad habit of getting ahead of myself. All the papers do advise the two star procedure. Well, I did it last night in less than ideal conditions and it somewhat worked. Improving my exposure times is the ultimate goal.

I think I had the meridian/equitorial star but did not change perspective to the east (or west of what I've been reading.... West is a better direction in my location) I think the correction steps would be reversed in that case correct? Still trying to get the imaginary line concept down to a science. Are there static stars at given latitudes that are good for this procedure? Or, because the procedure is so location specific they are not supplied.

The program was really easy to use with PHD, I need a couple of more so so nights to practice with this (another learning curve!!!!) to get it down.

Thanks Andy

hi andy,  it's been awhile since asking about ST... everything working fine,

however just one small question re: the timer??? what is the purpose of it???

i had thought possiblely, depending upon the magnification, you will set

timer to keep image in the FOV, or something like that... if i'm way off base,

it's okay, i can take it...

in closing, thank you guys, ( you andy, david and daniel) for keeping the forum

up and running for all us junkies...

Craig, typically the timer is used to insure you weight a sufficeint amount of time to see any drift. Many people use 300 sec (5MIN) as a standard. Some do prefer longer.

Set it (in seconds) for however long you wish and when it's done it'll ding. It's just a reminder for you to know when you've been drift aligning long enough. You can use it to time eggs if you want to.
