Paul, I use my Information window Target and Point Telescope Here feature to

center a specific star almost exactly. Use a prior image and locate an

easily found star then center the Information window Target on it.

Remember, 'both' images must be in the same Bin mode or this will not work.

If you flip Meridians you'll need a prior image on both sides of the

Meridian.



The Information window shows X-Y coordinates centered under its Target in

Aperture mode. Read these coordinates from your prior image then move to

the new image placing the target the same position. Double clicking the

image sticks the Target in the image and use the arrow keys to pinpoint the

exact position.



Using the Move Telescope Here feature, accurately Calibrated with at least

75% movement your imaging chip can tolerate, quickly gets the star within a

few pixels in short order. I'm not too picky as to the 'exact' positioning

because I Dither between images. Hope this helps...joe :)

Subject: [MaxImDL] Re-frame Target Help



It takes multiple sessions to acquire enough data for some targets. I

do not have a permanent observatory and re-set up equipment for every

session. A good bit of time is involved manually nudging the telescope

around to duplicate the frame from the previous session(s).



Is there a better or semi automated way to reframe using MaximDL, the

Sky 6 and/or PinPoint LE? I use PoleAlignMax every night to lock in a

great polar alignment and am amazed how fast PinPoint plate solves. I

can get semi-close using the FOV indicator in the Sky 6 and then

iterate manually using a corner star to get as close to the original

fames as possible. I would love to get some of this time back.



Thanx, Paul

Paul,



The easiest way to accomplish this is to plate solve your target prior

to imaging and ensure you are exactly on the coordinates you expect.



Then, the next day, you would plate solve your target again and match

up the exact coordinates you had for the first day.



This makes centering your target very easy.



You may also consider trying out one of the image automation programs,

like my CCD Commander. It will automate this process for you,

accurately centering your targets every time.



I hope this helps!
