  Truncated dropdowns
Posted by: razvan - 2019-07-12, 12:10 AM - Forum: SkyTools 4 Support - Replies (5)

I noticed two places in the UI where dropdown boxes are truncated; in both cases there's plenty of space in the toolbar to the right so they can be extended.

The filter dropdown in the Camera view only shows the first few characters. In the screenshot, the options should read "Color" and "O-III" not "Col" and "O-II". 


The Background Images, while wider, cannot display the default list of "Current Bright and Interesting Minor Planets" as seen below. This one is not a problem, it's just aesthetics.


I tested on my desktop, 1920x1080 and on my laptop, approx 1700x960 (it's 2560x1440 scaled up 150%); in both cases the ST window was maximized. The issue is present in 4.0e but was also in 4.0d.

  Surface brightness of Veil Nebula (West) is 99.9
Posted by: PMSchu - 2019-07-07, 07:39 PM - Forum: SkyTools 4 Support - Replies (1)

Hi Greg,

I just looked at the western part of the veil nebula in the Exposure Calculator and it couldn't estimate an exposure because the surface brightness is listed as 99.9 for the (V), ® and (Total) bands. The mag is listed as 7.0. The (V) band for the eastern portion is 19.2, the (total) is 18.0 and the mag is 7.0. The EC works with the eastern portion OK. The Imaging Project also shows 'Error' for the Exposure Time in the 'Filter' section of the 'Exposure Goals' tab. The "Info and Suggested Settings' box doesn't show the Surface Brightness data so it offers no clue about the source of the 'Error'. A screenshot of the Imaging Project tab is attached showing the 'Error'.

I don't know when the 99.9's entered the database, since I haven't looked at the Veil using the EC in a while. I just saw a nice photo of the Veil on the DPReview Astrophotography page & checked it out. I expect that the Veil will become a popular imaging target this summer.

  Observing List errors on Win 10 Desktop and Notebook
Posted by: Dennis - 2019-07-06, 12:32 AM - Forum: SkyTools 3 General Support - Replies (5)

Hi Greg

The SS2K Alignment Stars list is exhibiting strange behaviour:

Win 10 Pro Desktop PC:
Only 26 out of the 35 alignment stars are showing data. The remainder are blank and show zeros in the RA and DEC columns - see screen capture.

Win 10 Home Notebook.
I upgraded this from Win 7 to Win 10 as a fresh install i.e. all apps and data were deleted.
I installed ST3 from the CDROM (full install) and when I Imported the SS2K Alignment Stars List from SkyHound all 35 entries were blank with zeroes in RA and DEC columns.

I have uninstalled ST3 on the Notebook and re-installed again with the same results?

I haven't used ST3 for several months prior to observing this behaviour on both the Win 10 Desktop and the Win 10 Notebook.

Any ideas on how I can fix this?



Win 10 Home Notebook:

  • On the newly installed Win 10 Home Notebook, all the Star Observing Lists (e.g. Skiffs Red Stars, AL Carbon Star, etc.) are all blank with zeroes in the RA and DEC columns.
  • Also, in the Deep Sky Group, the South African Astronomical Observatory Best contains over 50 blank entries, all with zeroes in the RA and DEC column for those blank entries.
  • I have just quickly browsed the Current and Default Lists and they appear to look okay, with no blank entries displaying.
Win 10 Home Notebook.
I noticed that AL Doubles were in the Default Group and AL Carbon in the Star Group on my Win 10 Home Notebook and they displayed differently in the RT Tab as shown in the following screen captures:


Both displays appear to be incomplete in terms of data fields - this is getting stranger and stranger, given this is a fresh install of Win 10 and a fresh install of ST3 on this Notebook.

  Questions about the interactive atlas and camera view
Posted by: razvan - 2019-07-04, 06:07 PM - Forum: SkyTools 4 Imaging - Replies (4)

Hi Greg,

I have two so I'll use one thread (hope you don't mind) since they are both related to the same views. 

  1. Is it possible to disable the rendering of the constellation lines & boundaries (or, more generally, of a given line type)? The chart preferences windows allows setting the line thickness, but its value starts with 1 not 0. I can sort of hide the lines by changing the colour to black but that works if the sky background is black. If I change the chart type to atlas on white background, the lines are again.

  2. Is it possible to extract the list of objects in the camera view (to be more precise, as visible with the current magnitude limits? Use case: I take an image based with a chosen target and would also like to know which other objects are in, particularly if some are interesting such as quasars. I can set the mag limits to match the captured image and it'd be great to be able to click a button and get a list of objects in the FOV (useful columns: Primary ID, Alternate ID, Type, RA, Dec, Mag).

  3. Is it possible to select the default gain that is used for a camera? I have a ZWO294MC Pro and configured the 300 and 400 gains which I use most often for EAA. Every time I open the camera view, it defaults to Gain 300 (perhaps because it's the first one entered or the first one alphabetically). This is a very minor point, more like a curiosity. 
Thanks and happy 4th of July!

  IQ filter & the Q column in Target Selection
Posted by: razvan - 2019-07-04, 05:13 PM - Forum: SkyTools 4 Imaging - Replies (3)

Hi Greg,

The value of the IQ filter under Night Filters (which is supposed to be better-or-equal than the value chosen in the drop down box) appears to be replicated in the Q column instead of the real value. 

  • If I don't enable night filters, than the Q column contains the correct value (A, B, C, D or nothing), as expected
  • If I enable the filters and choose, say, C, than the list is shorter (as expected) but all the rows have 'C" in the Q column, no matter what they had before. See the attached "_c.png"
  • If I then choose B, than the list is even shorter (as expected) but all the rows have 'B" in the Q column. Even those who had C before.  See the attached "_b.png".
So it looks like when the filter is enabled, the filter value populates the Q column. I've converted the screen captures to B&W so they fit under the 500KB limit.

  "ComboBox3" in the Add Observation dialog
Posted by: razvan - 2019-07-02, 11:55 AM - Forum: SkyTools 4 Support - Replies (4)

The top right combo box has that label (I presume it's the default label since it's the third combobox in that dialog) and its purpose is not clear. There's no value displayed when I click on it (is it intended for the telescope, perhaps?).

  St4i 4.0d Image Scale Grade issue
Posted by: gregwjones - 2019-06-29, 05:14 PM - Forum: SkyTools 4 Support - Replies (7)

In the Target Selection tab I have several targets that Sti4 displays the Image Scale Grade as "---" even though it displays the Image Size as several hundred pixels. This is confusing to me. It should display the grade as "A", 'B", etc.

See the attached screenshot with M101 highlighted and the Image Scale Grade listed as "---".

  Jupiter GRS Longitude
Posted by: Joe Stieber - 2019-06-28, 05:05 PM - Forum: SkyTools 4 Support - Replies (15)

I was wondering if there is some way to update the longitude of Jupiter's Great Red Spot in SkyTools 4?

In SkyTools 4.0d Imaging, the current GRS longitude is 289.4° compared to 312.3° per WinJUPOS (the ST4 value can be determined from the Object Information box for Jupiter; take the current central meridian value and subtract the GRS angle). The 22.9° difference between ST4 and WJ results in ST4 showing a current GRS central meridian transit about 38 minutes early. I can't find any way to initiate an update or enter the value manually.

Another glitch I noticed. I like the addition of the "Display Direction Indicator" to charts, with the equatorial version in ST4 showing N and E on arrowed lines connected at a right angle. They are correctly oriented on-screen (in various directions depending on the view and time), but not when printed. With both the print preview screen and a paper printout, N is always parallel the vertical edge and E is always parallel to the horizontal edge, regardless of the on-screen orientation. I'm using a Dell i7 laptop with Win 10 and a Brother wireless laser printer.

My apologies if I missed either of these items in any earlier posts.

  overhead/naked eye simulations not rendered.
Posted by: razvan - 2019-06-23, 12:41 AM - Forum: SkyTools 4 Support - Replies (4)

Hi Greg,

Something odd that's happened several times on my laptop (Thinkpad T470s with high DPI/Windows 10)  ST 4.0d. The naked eye or overhead sky simulations are not rendered (the atlas is fine). A "Visual Sky Simulation" window appears in the task bar but as if it were minimized. Any attempt to bring restore its size or bring it to front does not work (the window is not rendered). Hitting Alt-Tab shows what I'm attaching: a mostly black screen with some white lines, as if something were rendered block by block and it stopped. Always in the same position. It does not matter if I try to open the sky simulations directly or if I open the atlas first (which works). If I do the latter, when I chose one of the two sky simulations from the dropdown box at the top, the window is minimized and I'm in the same situation as if I opened it directly. In case it matters, the minimized window is response to right-clicking & closing it.

I upgraded the display drivers (details below). I turned off display scaling. No change. I don't remember if it worked in the past (I bought it a month ago) because I'm also using ST4 on a Dell desktop where everything works (the video card is different) and mostly used the laptop for planning. I did notice the problem but in the past but am not 100% sure if it worked at all. 

I realize it's hard to debug these things from a distance so my questions are: (1) have you heard about such a problem in the past and (2) is there any application logging to enable or anything I can do to further investigate it? As a programmer, I'm thinking perhpas there's some commonality in the rendering of the sky simulations that is not used by the atlas. 

Thanks for any support you can provide.

  Print Target Selection page
Posted by: galljj - 2019-06-22, 06:23 PM - Forum: SkyTools 4 Support - Replies (1)


Is there a way to print the target selection page ?  I've been abe to snip it, and ten use paint or otherwise to print it but that's limited and many extra steps.

I looked, but could not find any help topic on tis issue.
