Can you please advise whether SkyTools - version 3 or 4 - will let me output an observing list to CSV or excel?

Many thanks

  Imaging System Setup - camera dark signal
Posted by: dcaskytools - 2020-01-19, 05:54 PM - Forum: SkyTools 4 Imaging - Replies (2)

I am setting up a new camera (the ZWO ASI6200MM Pro) in the SkyTools 4 Imaging "Edit Camera Data" dialogue box.  
The dark current for this camera at -10 C (which is where I typically operate my cooled cameras) is 0.00098 electrons/sec/pixel.
I enter this value in for the camera's Dark Signal...and save the settings.  
When I reopen the Edit Camera Data dialogue, the Dark Signal value is shown as "0.00"...

Does the tool automatically round down values less than a certain threshold to 0.00...?   Or is the value saved as 0.00098, but only displayed as 0.00 in the dialogue box...?

  Install without an attached drive?
Posted by: dtlnew@yahoo.com - 2020-01-19, 05:01 PM - Forum: SkyTools 3 General Support - Replies (3)


I would like to install ST3 on my new laptop but installation seems to required a DVD drive.  I copied the install files to a portable HD in an effort to install that way but I'm stuck.  Is there an easy trick or work-around to this?

  Trouble Re-installing ST3 on Windows 10
Posted by: Natscher - 2020-01-18, 06:09 PM - Forum: SkyTools 3 General Discussion - Replies (1)


I am not having any success re-installing my DVD copy of SkyTools 3 on my 2011 17" MacBook Pro with Parallels/Windows 10.  This configuration was a recent hardware/software upgrade for the 17" MBPro to SSD and Parallels 15 so it can run Windows 10.  The DVD install allows partial installation but won't complete the install.  I've tried the install both with the autorun and setup files on the DVD but both fail to complete the install. Is my DVD copy of ST3 out of date for this Win10 system?

When will ST4 for Observing be available?

I've been configuring my imaging systems in SkyTools 4...in particular, inputting filter data for my Chroma LRGB, H-alpha, SII, and OIII filters.
Is there a way to share the data with other SkyTools users, similar to the ability to share new camera data...?

When using the Interactive Atlas and displaying Saturn, is there a way to get the software to display more than 7 satellites? I know that any beyond those 7 are mostly beyond observation but I want to plot them. Mostly interested in Janus, Prometheus, and Epimetheus.

  Will v4 read your site settings in V3?
Posted by: C8Es102 - 2020-01-16, 04:10 PM - Forum: SkyTools 4 Visual Observing - Replies (2)

Wondering V4 is going to read specifically my sky clear view settings and EP's and the like. Like an idiot I spent a long time mapping my clear sky view and after I put them in I lost the paper I wrote them on Sad

I must admit that I am thoroughly confused on how ST4 works. I might be overthinking it. For example, I was looking for something that would help me determine something like optimal sub exposure time for various targets. I put this into practice recently and I'm just not seeing something correctly. I am using a QHY163M camera along with a Skywatcher 80mm evostar at 480 mm (.8FR). I shot M42 binned 1x1 at a gain of 50 and an offset of 35. (I included my settings etc, under a post about the Crab nebula where I was equally confused). The median ADU value in a 30 sec. exposure of M42 yielded ~1250 ADU whereas a 5 sec. exposure gave a median of ~683. Under the exposure calculator for the same night using a single exposure time of 30 secs., ST4 is showing : Signal: 359 ADU -Sky: 101 ADU/pix

What am I missing? Am I just using the application incorrectly? I had all of the settings for the same night I actually shot the images (1-5-20). I have experimented with this for other objects and I never seem to be getting ADU values from ST4 that jive with what I see in reality. Sorry for being so dense but I could use some mentoring....

I suppose what I thought ST4 would do is tell me what sub-exposure times and how many images I should take for a particular filter under the conditions I give it. Maybe my misunderstanding is in the SNR concept. I do know what SNR is but perhaps I'm a bit weak on how much I need in total and for individual pictures. I also use a spreadsheet I made from information I gathered online which supposedly tells me the min and mix ADU values I should shoot for regarding sub-exposure times in order to swamp read noise. That calculation seems to work but doesn't give me anything like I am getting from ST4. The spreadsheet calculates a min of 662 DN and an ideal of 899 DN. Thanks for any help. Again, you can see/obtain my settings a few posts down about the crab nebula.

  How to get alignment stars for syscan
Posted by: C8Es102 - 2020-01-12, 03:15 PM - Forum: SkyTools 3 General Discussion - Replies (3)

into a catalog without having to type them into something. I have a list but it is only the names not the other information. My HC is a Syscan 4 from SW/ORION. I can of course import just the names but that would not do me much good. I know that Visual 4 is very close and this is something I need to get done, so if I have to type them I need to get started.

Thank you for any and all suggestions.
