For several years now I have offered a collection of my best astro-photos on a USB flash drive for use as a slide show, screen saver, wallpaper, etc. The collection has now grown to over 45 images and I’ve added an application (for Windows computers only) that does a slide show with configurable text overlays.
Each image has 3 type of information available; the title, object information, and technical data. The “Setup” menu allows you to select which of these 3 is displayed during the slide show, but you can also switch it “on the fly” using hotkeys. For example, if you want to see the full image with no overlay you can uncheck each item in the setup, but as you are enjoying the show, if you get curious about what the object in the photo is, just press “t” to display the title. If you then decide that you want to see the title for each image, press <SHIFT>”T”. Likewise, more information about each object can be displayed/undisplayed using the “O” key and technical data can be toggled on/off with the “D” key.
Astro-Flash can also be used with many Smart TVs by pluggin it into a USB port on the TV and navigating to the Images folder to start a slide show. The images can also be copied to a cell phone or tablet so you always have them with you.
I have also removed the “AstroCalc” spreadsheet from Astro-Flash and made it available on this website, under the Support tab. Originally, I expected that fellow astronomers would be the primary customers for Astro-Flash and that they would appreciate this bonus spreadsheet. But most of my Astro-Flash customers are not astronomers and would only be confused by the presence of this spreadsheet. If you are interested in a handy tool to calculate useful numbers for both visual astronomy and imaging, download the spreadsheet here.
