I can export to file or stx file from Visual but am unable to see them in the import browser of Imaging.
I know the folder name and can browse to it but no files can be seen.

thanks

Hello!

The attached STX list contains 44 red supergiants with apparent magnitude 8 or less (on average in case of variable stars). Most (35) are of spectral type M with the remainder of type K.

They owe their monster status to their enormous hefts and luminosities.

Good description of these monsters:

Hi MP hunters,

The NEA 2017 WN13 is predicted to make a close approach in early April. According to ST4v, using the osculating elements for 2022 Mar 30 0000, peak brightness of 16.3 magnitude will occur around 2200 EDT on Apr 2. It will be in Hydra moving at 65.5"/min. While it's beyond my 13" scope from Ohio, ST4v predicts that it would be visible from southern hemisphere sites, like Aukland, NZ on the nights of Apr 2 in Hydra & Apr 3 in Pyxis (77"/min).

The uncertainty code for this object is 1 so the orbit is well defined.

This MP is right on the limits of what's detectable in a 13" telescope.

Hopefully the weather will cooperate, but these close approaches seem to be jinxing that (no surprise).

SkyTools saves Visual Observing lists and Imaging Target lists as .stx files. These files can be read by both SkyTools Visual or Imaging.

To share a list:

1. Open the Nightly Planner (Visual) or Target Selection (Imaging) tool and select the list you want to share.

2. Click on Share/Export List and select Save as stx File

3. When prompted, give your list a name and description.

4. Save the file where you can find it again

5. Start a post on this forum. Describe the list and attach it as a File Attachment by dragging it from Windows File Explorer to the Attachments are at the bottom of the "Post New Thread" window.

To import a shared list:

1. Click (or right-click) on the Attached file link of a forum post. Exactly how this works will depend on your browser. Save the stx file somewhere you can find it and note the name.

2. Open the Nightly Planner (Visual) or Target Selection (Imaging) tool

3. Click on Get Observing Lists and select Read from SkyTools (.stx) File.

4. Browse to the location of the file you downloaded and select it. Tip: take care to select the folder you want to place your file into so you can easily find the list and note the name of the list, which may differ from the name of the stx file.

Interesting possibilities for an outburst of the Tau Herculids in late May. This shower has been linked to the breakup of comet 73P/ Schwassman-Wachman 3 in 1995.

Hi MP hunters,

If you want a laugh, have ST4v speak the Object Info for the NEA 2022 FT2.

At least I got a LOL out of it.

Hi MP hunters,

It looks like we have another winner. The Near Earth Asteroid (NEA) 2022 FB2 is predicted to approach within ~150,000 km on Mar 28 at 1200 EDT when it will be in Antlia moving at 17.3"/sec. Max brightness is predicted to be 13.2 magnitude on Mar 28@1000 EDT in Crater moving at 12.5"/sec. I calculated the ephemeris at 2 hour intervals so, if you plan to observe this object, I recommend that you download the MPC's NEAs at Today's Epoch data file using ST4v's minor planet data tools to get the most recent elements & calculate an ephemeris for your observing location. If you just download the elements for 2022 FB2 from the MPC, you'll get the elements for the standard epoch - 2022 Jan 21, though.

This looks like a good object for folks in the southern hemisphere. I hope this is enough warning. Here's the predicted path as seen from Sydney, Australia: [attachment=2302]

Hello,

I attach an STX file. The list contains the stars of special spectral characteristics that Angelo Secchi submitted to the French Academie des Sciences in 1868.

Secchi investigated the stars contained in Schjellerup's Catalogue of Red Stars and found these 16 stars (a 17th star is not clearly identified) to be markedly different from all others. Today we know them as carbon stars.

The rating is based on Secchi's aesthetic evaluation.

Yesterday morning ~4:12CDT, a rock from space about the size of DWs Mini Cooper flew by at a distance of just 18,811Km. While only mag 14.8, it was moving 3.2°/min!! At the time, it was well below my horizon (alt = -46°) in the SSW.
Lately, it has been clear that we are getting a good many small rocks passing close by and even impacting at times. At time, there are 41 rocks within 0.05AU of my location. Good example is the previous discovery 2022 FD, discovered just 2.4 days earlier. 31 of these rocks are new discoveries. Makes one wonder.

Hi

how do I transfer my data from ST3 to ST4?

thanks
