  1. Hello, I am looking for tips to make a good targeting model with our az800. We will do with "Sequence" program that helps us so much. How many fields usually gives a good result? What Az and Alt step size is appropriate? We will let's do it without Rotator with tracking deactivated in AutoSlew. Should it be like this? We appreciate any experience you tell us. Thanks in advance, Miguel Chioare
  2. Hello, Of course the problem described below can be compensated with StarAlignment, then DynamicCrop... however the problem would deserve an explanation for me. I photograph NGC 6853 on October 16, 2019, then the next day, at the same time, with the same filter, and the counterweights in the same direction. Sequence uses MLPT for each series of shots, with a residual error of less than 1 arcsec. The file NGC 6853.trg contains the coordinates of the target: - RA 20h 00m 29s - DEC +22° 47' 00" On October 16th ImageSolver + FITS Header give me the coordinates of the center of the image: - OBJCTRA 19h 59m 39s (angular error 00° 12' 30") - OBJCTDEC +22° 43' 31" (angular error 00° 03' 29") October 17 - OBJCTRA 19h 59m 27s (angular error 00° 15' 30") - OBJCTDEC +22° 42' 38" (angular error 00° 04' 22") 1 - Images are not centered on the position specified in NGC 6853.trg 2 - Between October 16 and 17, the images are, in addition, frankly shifted between them. This is where the problem arises for me: - delta RA 00° 03' 00" - delta DEC 00° 00' 00' 53" If someone can help me understand this both problems… La Cebra
  3. hi all, i've been using sequence for many months now, and one thing that i've never really gotten to work consistently is the synch function in sequence. through experimentation i've found that i have to be almost within about 15 minutes of center otherwise synch will fail. however, if i use pinpoint through maximdl, i can be off by quite a bit. it seems that pinpoint "tries harder" than sequence. sequence fails after just a few seconds, whereas pinpoint keeps trying for up to a couple of minutes and many times succeeds after this long. i've switched catalogs, i've played with the "Expansion %" variable, (which i don't believe actually does anything!!) the 5x5 spiral search option is disabled on sequence. i've adjusted the Max Magnitude variable - i've increased my exposure time, decreased it (usually 7 seconds seem to get a good amount of stars) but nothing seems to help me get more area coverage for plate solving, unless of course i just use pinpoint from maximdl. i just don't know what else to do, and since MLPT and sequence fundamentally requires platesolving to actually work through a long exposure, i feel like i'm kind of crippled here. does anyone else feel like sequence synch is a lot weaker than pinpoint (even though they are supposed to be one in the same) ??? or is it just me??
  4. Hello. Can someone in order to write the steps to do the correct procedure for mapping the sky DDM86 in the Sequence. As for the correct setting for polar. . Editing DD85 I set the laser to the north. I forgot how it was done thank you

  6. so i'm not having very good luck with this. it'll solve maybe 1 out of 10 plates, and sometimes 0. :-( here's what i've tried: - i uploaded several of them to nova.astrometry.com and they solve, no problem. - i tried using pinpoint within maxim DL, and it solves them. - i've tried switching to the USNO A2 catalog i confirmed my arcsec/pixel resolution as well, so i know my binning and resolution settings in sequence are correct. i'm using exposing for 20 seconds, and my settle time is 3 seconds. not really sure what the 'secret' is. is there a logfile in sequence for this? does anyone else have trouble with this?
  7. Hello, is it possible to have two different versions of Autoslew and Sequence, say 5.1.1.6 and 5.2.0.4, installed on the same computer, so you can switch between them ? This would be great in order to play with the beta version and work with official version... Regards, Ralph
  8. Dear Sir, Are there any one who can conduct the MLPT in Sequence correctly over meridian without flip, with keeping "Telescope is East" ? I am living in Japan, which is north hemisphere as you know and using DDM85 Standard(DDM85X-SL). Please give me any advice so that I can conduct the "MLPT" correctly over meridian without flip. I am very satisfied with "MLPT" and Pointing file(16-Stars in East and 16-Stars in west), which I can get very "round stars" more than 40 minutes with 1880mm focal length in both East and West. But in case I conduct "MLPT" from East to West, over meridian but no flip due to my settings are below. In this "over meridian but no flip", I can not get "dot" results in MLPT after over meridian. Please see the screen shot: (or attached MLPT#1.PNG) http://i829.photobucket.com/albums/zz218/horiuchikazuo/MLPT1_zpsfa39bf73.png In this screenshot, I can not see last "2 dots" after over meridian. In addition, in case I execute "Load and Draw LPT File" function in More Tools section, the result is as below: (or attached MLPT_load&Draw.PNG) http://i829.photobucket.com/albums/zz218/horiuchikazuo/MLPT_loadampDraw_zpsff458ea0.png In this screenshot, Total Exposure time(min) is quite strange, which is -1387.8 and result dots are also strange !! I checked inside the 5Sarts.lpt with Windows "Notepad", there seems to be strange values inside which are highlighted in "Red" in the screenshot below: (or attached MLPT_test.PNG) http://i829.photobucket.com/albums/zz218/horiuchikazuo/MLPT_text_zps52d569d4.png I am using the following versions. -Autoslew: Version 5.1.1.2 -Sequence: Version 0.0.0.9 Settings in Autoslew are below: - Mount --> Type, Limits --> How far can you go through the Meridian with your German Mount ? : 30.0 - Mount --> Flip Options : stay on side I have looked inside old "Yahoo Group" and found similar issue which were raised by Mr. robert.pudlo dated Dec 2, 2011 6:44 pm. But I can not see any final solution nor answer for this issue. Thanks in advance and Best Regards, Kazuo Horiuchi
  9. Hi, yesterday I tried to use sequence with a very short focal length (80mm lens and KAF8300). Unfortunately sequence couldn't plate solve any image ! Maybe this is because I only adjusted the Plate Parameters Horiz Scale and Vert Scale? Do I have to adjust any other parameters? Who can help me ? Thanx, Ralph
