In order to control most astronmomical equipment you will need to download and install the ASCOM platform. This page collects together a number of extras including scripts, plug-ins, and third party software that works with MaxIm DL. MaxIm DL. SKU: maxim-dl. Complete observatory integration.
Controls all of your astronomical equipment. Integrates your camera, autoguider, filter wheels, focusers, camera rotator, telescope mount, observatory webcam, remote switches, weather station, and dome. Designed for efficiency. Create your own presets for finding, centering, focusing, and imaging sequences.
The system was operated in search mode, thus detections submitted to the MPC appear all over the detector field, not just the center.
In addition, detections were usually near the noise limit and are hence subject to random variations. Compare with other observatories, amateur and professional, and remember that many amateur imagers are relatively narrow field and distortion-free, plus many are being used for single target astrometry near the center of the field. These numbers are as good as any observatory out there.
And this is across the entire field of a very fast instrument, a worst-case scenario. Furthermore, PinPoint has been improved through many revisions since this data was taken. Underlying the astrometric solution and distortion mapping is the accuracy of the X-Y positions of each detected object in the image.
This is the basis of accurate astrometry. In , amateur astronomer Donald Bruns replicated the Eddington Experiment which was used to test Einstein's General Relativity by measuring the tiny deflections of stars near the Sun during a Solar Eclipse. Bruns used PinPoint to measure the precise star positions on his eclipse images, made difficult by the solar glow. PinPoint's automated detection and centroid measurements were validated by manual measurements made in another tool and found to be "identical".
As the size of images increases, the demands on an automated astrometric engine increase steeply. Many of the available astrometry packages bog down when asked automatically match more than a dozen or so stars, or detect stars in a field containing more than detectable stars.
All 12 came back "red" for WCS solving. However, after uploading to Astrometry. I have not done any systematic experimentation, but it seems to happen when images are taken near or just below the celestial equator. Again, it seems to be related to where in the sky the images are obtained. PinPoint vs Astrometry. Any clue Geir? Clear skies to all Stefano 'T5' Padovan.
Log in or register to post comments. PinPoint problems 2 - can we see your images? Stefano, Can you make your 'problem' images available? I would like to examine them. Thanks in advance. Pin Point problems. Hi, unfortunately I deleted the images just a couple of days later and If an image has no pixel scale information available in its FITS header, you can specify it manually using the Pixel Scale Editor , described below.
Search Sky Online : In some situations you may not know the approximate location on the sky, or perhaps even the rough plate scale. One common problem is the loss of telescope mount sync due to hardware failure, power outage, etc.
Also occasionally you may want to analyze an image of unknown origin. In this case, click the Search Sky Online button. What this does is extract the plate stars using the current Detection Setup. Next it passes this information on to a blind solver web service called astrometry. Usually this takes a few seconds, but in rare situations could take as long as ten minutes. During the process a blank command window pops up on the screen; to abort the operation simply close this window.
Search Sky Online only determines the plate center and image scale; it does not determine a precise astrometric solution. The Approx. Center and Pixel Scale fields will be updated automatically.
To complete the full solve, click the Process button. Finally, we have the Catalog Setup. You can select the catalog to use from the list. The choice of catalog depends on which catalogs are available and the scale of the image. The following catalogs are highly recommended for general use - pointing correction slew refinement , image alignment, etc. Highly recommended for general usage pointing updates etc. Advanced users making scientific observations may wish to use another catalog.
The following catalogs are also supported:. USNO B1. NOMAD net - online access via internet. We strongly recommend the GSC for most pointing correction purposes. The only exception would be for extremely narrow field of views long focal lengths , such that the GSC does not have sufficient stars. If, and only if, you require extremely precise astrometry e.
However please be aware that plate solve reliability will not be as high; therefore for telescope pointing purposes we do not recommend using the UCAC4. For catalogs on disk you need to select the location of the catalog using the Path… button. Please note that Astrometry. To make sure the analysis is performed quickly, you can instruct PinPoint to ignore catalog stars outside of a particular Magnitude Range.
Enter appropriate minimum and maximum magnitudes into the two fields labelled Use stars from magnitude.
