Polypus 2.07 supports plate solving

In this version plate solving is supported by visual pin point engine. You should install it and GSC catalog on your PC. These installation are not part of Polypus installation. After that in the configuration dialog in the "Plate solving" page you can enable the Pin point engine use, select folder where GSC catalog is and set the frame expansion (in percentage) used for star searching.

In the Photo form a new button is present: "Solving". It is available after a shot is done, even if image not saved. This starts the Pin point action and if the match with catalog.

If the match between image and catalog is found the following page is shown where you can see: numero of stars used from catalog for match, the found coordinates, the frame roll angle and the error between toe current instrument position and shot position.

Pressing the Ok button you can sync the telescope with the found position

Polypus 2.06 support multiconfiguration and up to 5 instruments

 Whit the versione 2.6 Polypus support more then one configuration. Each configuration is saved in xml file in the folder |Documents\Polypus2\Configuration. In this way is easy move a configuration between PCs. In the first configuration page it is possbile create configurations and select the current one

Second configuration page can be used to select options related to the base observatory equiments: mounting, dome, switches. 

Generally under the same dome, over the same mouting can be present more then one instrument, each of them have different caratteristics and devices. Now Polypus can manage up to 5 instruments. The setting is done with next configuration pages. 

For each instrument it is possible select type from: Photo, Spectroscope and PEC.

Photo allow the standard management for images.

Spectroscope use different algoritm for focusing.

PEC implements a mounting adjustment from position error detected.

Each instrument can have its: camera, focuser, filter wheel and cover calibrator.

In case of spectroscope an additional focus driver can ba use to move the grid position in order to change the center of spectra image.

 

A new ribbon bar enable you to select the current instrument and act on it. With the element on this bar you can take shot, change filter, do focusing, manage cover

Status bar follows the current instrument selection, camera, focuser, filter wheel, cover are related to it

 Test for focus

with the version 2.03 the focus sequence was tested on the filed and adjusted.

In case of the procedure is aborted focuser is set the position where it was before so it can be activated again with the same sequence.

Now Polypus2 supports scripts

 Whit the version 2.02 the script support is introduced. 

Script support is finalized to a full automatic observation session even without people in the observatory

The first change you can find is in the menu. Now an additional ribbon menu named "Automatic" allows you to select and edit three different task script. One for each specific purpose.

Observation task script: where you can put all the observation activities

Time task script: where you can put activites you needs where a defined time (e.g decondense)

Closure task script: where you can put activities for observatory closure and final activities like fla, dark

Second big change is a specifi page able to edit and run scripts.

On the right you find the syntax colored editor for script writing. Using these element you can work off line loading, editing and saving every scripts. During editing syntax color allows you to see immediatly possibile syntax error. 

On the left element you see the task list in execution with their state and the current executed script where current line is highlighed. On the side you can check the current state of script variables 

Using the help button you have a page helping you in the script writing.

When you select the function sheet you can see the list of all available functions whit explanation and input/output parameters

Using the check button you can run a preliminary script check, the result of this check is showed in the bottom element. Its allows you to discover errors in the script before the run.

In the installation are present some script example in order to have an explanation of the script possibilities.

Polypus 2.01 version ready

 

The second  useful version of Polypus is ready, version 2.01.

you can find it in resources

Photo menu is updated so to manage three cameras: for photo, for PEC and for spectroscope. 

Pec camera has its own comand and window. It is possibile acquire image in loop and activate correcion so to correct periodic error.

Windows for photos was changed 

The focus precedure was inserted so now it is possible move focuser, take photos and compute for each the FWHM. Values appears on a graph and the position correspondig the minimum value is computed. At the procedure end focus is set on that position

Stile of window was changed in order to shrik the needed space so more information are available. Different color is used to recognize readonly text box. In the status window all elements are collapsable

Polypus 2.00 version ready

 The first useful version of Polypus is ready, version 2.00.

you can find it in resources

Now the camera management is implemented so photos can be taken. A new menu bar is present where you can select exposure and binning, assign name to the object. After that you can run a shot.

A window is dedicated to the photo showing. Adjusting the configuration photo can be showed with the same position and scale as chart in order to make it easy the field reconizing. On the left you can see the scaling information/setting, a zoomed area where the point is, moreover you have info about the image quality and star FWHM. 

An automatic dark sequence procedure is available. It allows multiple shots. If camera has shutter it is not opened. if it don't have, photos have to be taken in the dark. File are saved with a name cointaing the CCD or dome temperature and exposure time.

An automatic flat sequence procedure is available where dark is taken with the same exposure time. Just after the flat shots are taken flat light is turned on. 

An automatic shot sequence procedure is availabe with the possibility of filter change. You have to select the number of shots for each filter. For each filter you can select it own exposure. In case focus change with filter you can ask to use focus positions stored in filterwheel. When you start the procedure it is able to: change filter, change focus, take shot, change filter, change focus ....

A window can show all the command run the Polypus in the current session. It helps in case of somethig goes wrong, specially when observatory is unmanned.

Polypus2 Objects

 I come to you after days with the second beta of Polypus2 software. You can download it from resources.  In this time I have implemented the object view. This is activated by the command in the view menu. Here you can select the ephemerid epoch and, in case of near object, show the topocentric coordinates.

In the object view it is possibile see some object lists: 

• Favorites
• sync stars
• Planets
• Asteroids
• Messier 
• NGC
• UGC

For selected object is showed the position in the sky, the sky chart centered where object is using GSC catalog. Some additinal information are shoed. when object is over the horizon it is possible command a telescope goto on it. Objects can be inserted in the favorites list.

Sync stars list contains 20 bight starts with low declination along all right ascensions. This allow you a precise telescope sync. Star position takes in count the proper motion

Planet list contains all solar system planet plus Sun and Moon. 

Sun and Moon positions are computed using formulas from “Astronomia con il computer” by Janes Meeus.Mercury to Neptune positions are computed using VSPO theory. 

Mercury to Neptune magnitude are computed using formulas from “Computing Apparent Planetary Magnitudes for The Astronomical Almanac” by James L. Hilton US Naval Observatory

Asteroid list shows the position of object in MPCORB.DAT from Minor Planet Center, positions are computed using formulas from “Astronomia con il computer” by Janes Meeus.

Using the tab sheet Altitude is it possibile see the observation condition of the object in current (or selected) night. On horizontal axis you have the local time on vertical axis the object altitude. Yellow backgroung are for day light, blu background for twilight and dark for astronomical night. Red line show you the object altitude. Because the moon can often annoy astronomical observations it is possible show also the moon altitude by a green line.
