Here's one to save you from racking your brains like I did...... I've been saving my fields using Autostar Envisage in the fitsInt format for the last couple...
Hello Ric, the Envisage software does a lot of things to get pretty pictures soon, but these things (and the assumptions on which they are based) are not...
After a break of two month (sorry...), a new "Image of the Month" for December 2005 is now online at the Astrometrica web site, <http://www.astrometrica.at>....
Hi all, I'm a newbie with the program but since I have change my ISP, a couple of weeks ago, it's impossible for me to update or download mpcorb from inside ...
Hi Herbert, Thanks for your answer. Yes, I have problems with that FTP direction from browser and from FTP program (CuteFTP). I will try to find where is the ...
I tried to contact Gina Allegretti from Cuorgne, Torino, Italy, trough the e-mail adress "proieti [at] misper [dot] it", but my messages keep bouncing. ("550...
I hope I'm not stating the obvious.... I also use CuteFTP and I had problems until I realised it can only connect to FTP addresses if you turn off Norton...
The issue of correct absolute timing is of particular interest to me thru involvement with occultation work - esp occultations by asteroids. There is a real...
... Dave, I agree that there is a big difference between accuracy of relative timing compared to absolute time. However, I suggest you may be overly...
Minor correction: 2005 UW5 covered 17 degrees (not 19) in 2.4 hours. Richard Miles ... From: Richard Miles To: Astrometrica@yahoogroups.com Sent: Wednesday,...
... I agree. My experience too is that we can get much better than 1s with tools like D4 which use SNTP servers. It was pretty obvious on the residuals blocks ...
If you are working with SBIG cameras the time stamp in the header is recorded only to the nearest second . Sub second accuracy elsewhere doesn't mean much,...
... That's interesting. Is this a "global" feature on all SBIGs (ST, STL) and is it independent of the control software and of the used driver? Reiner...
I am not sure of other software, but this is the case with CCDOPS (SBIGs Software). I have seen this with the ST-6, ST7, ST-7e, ST-9e and the STL1001E. I...
It is dependent on the software, Version 4 of MaxIm DL added a shutter latency calibration routine when calibrated the software will record with a resolution...
I have just rechecked a number of images taken with WIN CCDOPS V5.38 build 2-NT. In each case the exposure duration is shown to the nearest 0.01 sec, but the ...
There have been some interesting comments on this - but all from what is at best a theoretical perspective, not necessarily taking all the issues into account....
Dave, I think you are too pessimistic. I agree that GPS would be the better solution. But my current setup is not that bad as it sounds here. Also all...
... Well, could it be that CCDOPS synchs the shutter to really open only at full seconds? Then however they should give the start of exposure time as X.00s not...
... Yes, but take care as displays on GPS devices are sometimes delayed as well and the delay is sometimes even dynamic depending on the CPU usage. If I...
Pessimistic or realistic? My main point is that if your precision is 1 second or larger, the issues that affect time precision are quite straight forward - and...
Reiner, I mean that type of clock running independently from a PC and displaying the time with gas discharge displays rather than slow LCDs. I think the clock...
GPS devices that do not have a 1PPS output can have serious delays in the time. On those GPS units the time is computed, rather than extracted from the raw GPS...
Herbert - a suggestion for a minor enhancement one day. Re the dialogue box for selecting images to reduce. When you have a large number of images in a folder,...
Hi Reiner, that is an interesting question. Someone know if CCDOps opens the shutter at full seconds? If no, is there another software with such a feature...
This whole issue was a lengthy thread on MPML 3 or 4 years ago. The one second resolution on PC clock was a limitation imposed by selecting a particular...
