  SkyTools works primarily on multiple star systems, not individual pairs.
Posted by: pmochocki - 2018-06-25, 07:14 PM - Forum: SkyTools 3 General Discussion - Replies (8)

I am now to the forum and I have posted my feedback here https://groups.yahoo.com/neo/groups/skyt...pics/15833, but this  forum is probably a better place.

I am using the SkyTool 3 for over a year now and I like this tool very much. This is not a new topic, but still I have some concerns.

>> SkyTools works primarily on multiple star systems, not individual pairs.
I understand it, but I do not really agree that this is the most convenient way to operate. At least not for me.

>> The Planner picks the pair that you are most likely to observe given your telescope and the observing conditions for the night selected.
Really - let us take an example:
Location: 54° 30′ 0″ N, 18° 33′ 0″ E
Time: Summer (June 2018)
Scope: Sky-Watcher ED120
Eyepieces: 4mm, 6mm, 10mm, 20mm, 33mm 
Star: 31 Cyg

Skytools suggests pair DE - the second component is 13.2 mag. Not visible in this scope at this time of the year. I added it to the list to observe AC: 3.8+6.9 mag with a wide 105" of separation but with a nice color difference.  

I know that this changes the architecture of your program, but giving the enduser the option to create a list where the user could work on individual pairs would be very beneficial.
I do ask to change the default behavior, but please provide an option (like separate list type).
I understand that different users have different expectations and usage models, so there are probably users that would like the tool to handle the logic, but some users (as me) prefer to have full control of their list.

Best Regards

  Display of DSS Images in Interactive Atlas
Posted by: jdupton - 2018-06-18, 04:07 PM - Forum: SkyTools 3 General Discussion - Replies (6)


   This is a silly question but I have not not found the secret method yet.

   I have had SkyTools3Pro for several years now. Over that period I have downloaded a large number of DSS images when using the Interactive Atlas display window. Recently, I updated my copy of ST3Pro to the latest Version 3.2K level. In doing so, my default settings were reset. (I did not lose any observations, equipment, observer profile, or anything like that; just the defaults for various tools appeared to be reset.)

   I can no longer figure out how to show DSS images in the Interactive Atlas. The old images I had seem to have lost their links or something. If I download new images, they do not display either.

   What are the magic incantations in the Preferences and View dialogs of the Interactive Atlas that will restore the capability of viewing DSS images in the Atlas window?

   Below are my settings now.

PHi! Trying to load the iTelescope data to my SkyTools, following procedure on the website. It seems to work, I get a message to restart SkyTools, but the telescopes, locations, and camera info isn’t available.  I’m runnzing the latest 3.2 version.

  Virtual Atlas orientation for Netwton/Dobson
Posted by: Ullomat - 2018-05-16, 10:42 AM - Forum: SkyTools 3 General Discussion - Replies (4)

Hi all,

I just don't get it straight in my brain so I have to ask a maybe easy question.
What orientation do I have to choose on the interaktive atlas of Skytools, when I observe with a Newton on a dobsonian mount?
Flip vertical, flip horizontal or both?

Thanks an always cs,

  ST3 Pro Camera data
Posted by: galljj - 2018-05-15, 02:59 AM - Forum: SkyTools 3 General Discussion - Replies (4)


I've been trying out the exposure calculator in ST3 Pro, for my typical rig which is an 8" SC @ .68, with an ASI294 camera.  I'm getting counter intuitive results, based on my experience with the camera. I'm pretty new to all of this, so I suspect I'm prone to newbie goofs.

I entered the data from here https://astronomy-imaging-camera.com/pro...pro-color/, using the relative response in bgr to simulate QE.  I typically operate at gain = 350 and T= 0 degrees C, and used the data from the charts for read noise, dark current and gain.  Read noise =1.2, Gain at 0.2 e/adu, and dark current .07 e/sec.  See below


I always use a LP filter - and Astronomik CLS (non CCD) but don't know how to deal with that in the setup.  Bortle 6 skies.

I'm not trying to do traditional AP, but rather electronically assisted observing. I'll often post process the camera's raw frame.  Good enough for me.

I can get decent images on the screen - see my capture of ngc 6503 here https://www.cloudynights.com/topic/14451...try8568040, post number 6679.

But when I use the input, ST3 says that I can't get SNR of 3 (marginally detectable) unless I'm at 22  minutes of 8 second exposures, which is twice as long and far less quality than the screen shot.

Besides the LP filter issue, I don't know how to use ST3 to deal with the stretching I obviously can do within the capture software.

Are there any tips you can give me for enahncing my use of ST3 as an imaging/observing tool, or are my expectations too high ?

Thanks for the great product.

  SkyTools3 has stopped opening properly
Posted by: Davos - 2018-05-13, 03:12 AM - Forum: SkyTools 3 General Support - Replies (3)

Yesterday my SkyTools3 Pro developed a glitch in that while it apparently opened, briefly showed its opening splash screen and displayed its icon in the task bar of my Win10 laptop it did not actually display on screen. Hovering the mouse over the taskbar icon showed a thumbnail image of the SkyTools screen but that contained no detail being simply all white On right clicking the icon I got the usual small menu offering to close the application and on selecting that I saw the usual small SkyTools dialog saying that it was some time since the last backup but offering to close anyway. On selecting to close, the taskbar icon was removed.

I have the installation CDs so I tried uninstalling and then reinstalling SkyTools3 but I still have the problem. My guess is that one or other of the SkyTools support files has become corrupted and needs to be removed or amended.

Version uninstalled : 3.2j R2 Pro Edition
Operating system : Windows 10

Can you please advise?

  Jupiter animation of 39 Frames, with GRS and Europa. Brisbane 21/22 Apr 2018.
Posted by: Dennis - 2018-04-27, 07:03 AM - Forum: Solar, Lunar and Planetary Imaging - Replies (1)

We had a clear spell in Brisbane on the evening of Sat/Sun 21/22 Apr 2018, although the seeing was quite variable, estimated to be between 3-5/10 on the Pickering Scale.
I grabbed 39 sets of RGB data, 30 sec each filter with a pause of 210 secs between sets, spanning 11:50pm (21st) to 03:15am (22nd) with Jupiter transiting the Meridian at 01:07 am (AEST). From these RGB sets I managed to generate a 39 frame animation.
South is at the top of the animation.
Tak Mewlon 210 F11.5.
TeleVue 2” PowerMate x2.0.
Camera=ZWO ASI290MM.
SX USB Filterwheel.
R=30 sec.
G=30 sec.
B=30 sec.
Pause=210 sec.
Focal Length=4830mm.
Start = 78 deg (E).
End = 57 deg (W).
Variable from 3 to 5 Pickering Scale.

Link to animation on PVOL website: 
I have attached a single frame from the sequence, where the seeing had dropped to around 4/10. It is interesting to see the larger image scale using the ASI290MM (2.9micron pixels) compared to my previous effort with the ASI120MM-S (3.75micron pixels).

  Yearly Planner?
Posted by: DaleEason - 2018-04-25, 09:26 PM - Forum: SkyTools 3 General Discussion - Replies (11)

Is there a way to list the objects in your list as to the best time in the year to observe them?  Perhaps best month?  I would like to order my list so that I know which months to plan for my objects.  I know about the yearly view in the individual object view but I would like to have that listed for each object in my list and then order the list based on that.

That was a request back last year on the old yahoo group.  You said you thought the next version 3 would satisfy that need.  I could not find that addressed anywhere.

  show sun spots from soho
Posted by: DaleEason - 2018-04-22, 07:17 PM - Forum: New SkyTools Users - Replies (2)

In your demo you quickly show how from the interactive map one can search for SUN and then press OK.  Then a view of the sun with sunspots is shown.  When I try it a little progress bar is quickly shown and goes to 100% then goes away.  But no image of the sun spots in produced.  I have skytools 3.2k DL Pro.  Any ideas what else I need to do?
