Hello,

Anti-virus software can pose a threat to the stability of SkyTools. Those affected report more of less random malfunctions, from not being able to access the built-in list of eyepieces, to apparently losing all of their observing lists.

There appears to be is a push to protect your computer from Ransomware. If Microsoft's approach is any indication, the idea is to protect your personal folders, such as Documents, Pictures, etc., from being accessed by potentially malicious apps. Unfortunately, what "potentially malicious app" apparently translates to is any app not developed by Microsoft or one of its large corporate partners.

Windows Defender now has a Ransomware feature. If enabled, it will block the access of SkyTools to its own files, causing it to stop working correctly. So if you enable it, be sure to also add SkyTools to the list of trusted apps.

This article explains how to do this:
https://docs.microsoft.com/en-us/windows...ed-folders

It seems to me that it is only a matter of time before this Ransomware feature in Windows Defender is enabled by default, which will wreak havoc with SkyTools.This also explains the new attention that is being given to files in your Documents folder by other anti-virus apps. 

OneDrive can be a blessing or a curse. The default behavior of OneDrive is to back up all of the data in your Documents folder to the cloud. With this feature enabled, a OneDrive version of your Documents folder is created and your SkyTools files are stored there. This is done seamlessly for the user. As a result, your custom SkyTools files are backed up to the cloud. They can also be shared between computers.

One problem that can occur is if your Documents folder is very large, filling your OneDrive past its quota. If this happens it is easy to purchase more cloud space from Microsoft, but very difficult to disable OneDrive and keep using your SkyTools files.

Another issue is the delay in copying files from one device to another. If SkyTools is started on a second computer and some of the files from the first have been updated, but not all, this could potentially cause random problems and could even result in data corruption.

SkyTools stores its custom user files in Documents so that people can find the files easily when they are needed for support purposes. I would have placed them into the AppData folder instead, but that folder is hidden from users in basic versions of the OS, making it a pain to explain how to enable access to it.

I am considering moving the SkyTools folder from Documents to AppData in order to avoid the heightened scrutiny of the Documents folder. If you have comment or concerns about this, please share them.

For SkyTools 3, one problem that can occur is if you have a large number of logs. The SkyTools 3 log files are large and this can fill your OneDrive past its quota.

  C/2019 Q4 (Borisov) - First Interstellar Comet!
Posted by: theskyhound - 2019-09-11, 09:17 PM - Forum: Comet Imaging - Replies (5)

The Minor Planet Center just released an orbit for C/2019 Q4 (Borisov) and I have added it to the current comets target list.

This comet was only recognized yesterday as being of interstellar origin (a first). It is currently brighter than 19th mag.

  confusion around Little Gem nebula
Posted by: Leif406 - 2019-09-07, 08:07 PM - Forum: SkyTools 3 General Discussion - Replies (6)

Hello,
I was recently working with the H400 list specifically in Sagittarius and may have found a little error. There is an object called "Little Gem" (that is its Primary designation, secondary is ngc 6818 RA:  19h 43m 57.8s, Dec: −14° 9′ 11.9″ . Yet Googling NGC 6818 describes this as a planetary Nebula in Sagittarius and it is not known as the Little Gem nebula or any 'name' at all. The name/designation "Little Gem" is assigned to NGC  6445 (RA:  17h 49m 15s, Dec:−20° 00′ 35″), at least per wikipedia. 

The more I use your  software the more deeply I appreciate your programming skills and the way your software works. Im really interested in version 4 Visual and looking forward to its release.

Thank You,
Leif Edmondson

  Primary ID vs Alternate ID populated in the log
Posted by: dw_Skyhound - 2019-09-06, 02:11 PM - Forum: SkyTools 3 General Discussion - Replies (2)

Hi,
I did a little searching to see if this question has been asked before and didn't find any specific solution.
I notice (take for example the Messier objects) the primary ID within the DB for most of these objects is the "MX" designator.
But for some of them the "MX" designator is populated in the Alternate ID field rather than the Primary ID field.

The system appears to auto-populate the Primary ID into the log entry.
And there doesn't appear to be any option for the user to edit that value.
So for example "KeyStone Cluster" is auto-populated in the log - where I would want "M13" - or "M13 Keystone Cluster"

For a given object - is there any way I can swap the Primary ID value with the Alternate ID value within the underlying DB?

Will it be possible in ST4V to have the Interstellarum Deep Sky Atlas chart numbers available as well as the U2000 etc. ones?

  Neptune, Triton, Nereid and a couple of Asteroids
Posted by: Dennis - 2019-09-06, 08:50 AM - Forum: Solar, Lunar and Planetary Imaging - Replies (1)

I used SkyTools 4 to locate Nereid a magnitude 18.69 moon of Neptune over 2 nights (01 and 03 Sept 2019) and was also pleased to find a couple of Asteroid trails on the 03 Sept images which SkyTools 4 identified for me.

I have overlayed the 01 and 03 Sept frames and replaced the Neptune/Triton pair with single frames from each session that were not blown out. These accurately depict the relative position of Triton mid-way through each session.

How good is SkyTools 4 Imaging. Smile 

Nereid is the third largest of Neptune’s moons, and the second to have been discovered. It was discovered on 1st May, 1949 by the Dutch American astronomer Gerard P. Kuiper (for whom the Kuiper Belt is named) using photographic plates from the McDonald Observatory in Fort Davis, Texas.

Cheers

Dennis

  Wondering if I've got something set wrong
Posted by: dw_Skyhound - 2019-09-02, 08:39 PM - Forum: Beginners Forum - Replies (4)

Hello,
I’m reviewing some of my personal viewings of objects with “difficulty” indicators displayed by the system.
For example, on the night of August 20th I easily found Messier M13 with my 10” dob.
Personally of the Messier objects I might consider M13 to be one of the easiest to find.
The system calculated this object as “Detectable” for that night.
Which to me would seem to indicate I might not find it easily – and yet I did.

On the other hand I’ve been trying to view the cat’s eye nebula “NGC 6543” in Draco
I looked for this object 4 different nights without success – even though I know my scope is set right on its location based on star patterns.
Now the system “difficulty” indicator for this object is displayed as “Obvious”.
And that doesn’t make sense to me.

I’ve got the geo-location and time set correctly as much as I can figure.
And I’ve got “seeing” set to “Average” and “Naked Eye” magnitude set to “6”.

On the one hand I’m wondering if its silly for me to be concerned about this
But then again if I’ve got something set incorrectly – I’m forever going to get “difficulty” indicators I’m not sure I can trust.

Any advise is welcome!
