Good Morning- My 23- year old daughter Autumn is on the aircraft carrier USS Nimitz which is currently on a long underway in the Pacific Ocean. She works on the flight deck and recently during a lull in aircraft launches she captured some beautiful star portraits. I wanted to share these as I was interested in how many constellations I could identify not knowing the ships position and at least if I could estimate its latitude. I came up with an answer that turned out to be pretty close. She works 10pm - 6am ship time so she gets to see some spectacular dark skies. If anyone would like to try estimating the latitude the Nimitz was at when these were taken - just reply to this thread. Otherwise I thought it would be cool just to share her pictures. The stars are short trails due to the motion of the ship. Myron

Well here we go again. What looks like clouds in the distance in this picture is wildfire smoke. Hazy skies ahead. Myron

Came across this little pancake house in Williamsburg Va. I’d love to see their menu! Myron

Please share them with your club members, use them in your newsletters, and post them to your website and social media pages. The mail system I am using limits me to 4 attachments, so I'll attach the JPG versions of the sky maps.

? Dear RAC, Looks like a useful resource. Website is legit. Myron Begin forwarded message: From: jty.astro@... Date: May 23, 2025 at 5:31:01 PM EDT To: jty.astro@... Subject: Free Astronomy Book - PDF Download Reply-To: jtyrep2020@... ? Hello, James Yoder here, I am a co-author of a new Free PDF book called the Star Hopper’s Guide to the Galaxy. I though you might want to pass this information along to your club. Thanks! James Yoder The Star Hopper’s Guide to the Galaxy is a free PDF book created for astronomers in the northern hemisphere who do not have a GoTo telescope or are interested in finding objects using the star hopping technique. The book along with additional resources can be downloaded from the ArtCentrics website at https://artcentrics.com/books/ The book primarily consists of star hop instruction sheets developed by Jim Mazur that were initially made available on his website Skyledge.net. This compilation contains over 170 instruction sheets with over 250 objects. Each sheet contains two star charts; the first chart is used to help orient you to the night sky and immediate area around the target using familiar constellations or asterisms such as the Big Dipper, the Summer Triangle, or the Great Square of Pegasus. The second chart is a detailed road map on how to hop to the highlighted objects. Information on the targeted objects is provided, as well as a small image of the object, when available. The book is organized by constellations and the targets within the constellation. Each constellation has a page that summarizes the targets in the constellation along with a table listing basic information on each of the objects. The table includes the name of the object, the type of the object, links to the finder chart (within the book, and on the Skyledge.net website), aliases for the object, and some basic stats such as magnitude, separation (in the case of multiple stars), surface brightness, and size. A chart highlighting the constellation is also provided on the page along with online links to Wikipedia articles where more information on each of the targets can be found. The constellation summary page is followed by an image gallery where images for many of the targets are provided for reference. The book was specifically developed to be printed out so it can be taken out in the field. One can print out sections as needed, or print the entire book and place it in a binder or have it spiral bound. Additional functionality is available when utilizing the book on a PC or smart device such as an iPad. Many links with additional information are available throughout the book with the purpose of providing in depth information either in preparation of a viewing session, or additional research after a viewing session. The book is copyrighted under the Creative Commons Attribution-NonCommercial 4.0 law, so it can be freely printed and distributed provided there is no profit involved. We think this book will be a valuable tool to help the observational astronomer have a productive viewing session. James Yoder, Andrea Matthias, Jim Mazur

Dear RAC, I was contacted by a gentleman named Stephen Keating who will be moving out of the area in July. He wants to donate his two telescopes to anyone that would like them. One is a Celestron 70mm refractor and the other a Meade 4.5 “ reflector. See enclosed pictures. They are in mint condition. If you are interested Stephen says you can call him directly at 571-226-6243. I believe he lives in Fredericksburg. Myron

Dear RAC, Last night was a nice clear night so early this morning I had some time on to obtain another test image using our new Station 3 telescope-a Stellavue SVX102 T-Raptor and ASI 2600MC duo camera. Here is a compressed image of the result. As Pete mentioned in an earlier post-we still need to install a field flattener to sharpen up the star images at the edge of the frame. However, this image gives a good idea of the FOV and capabilities of our new station! Myron

Dear RAC and guests, Our next club meeting will be this coming Wednesday starting at 7:30 PM. The program will consist of a training on the use of our MSRO/RAC remote telescopes. If you have an interest in remote observing and would like to either task the club telescopes with a target request, or even better learn how to operate the telescopes yourself-then youll definately want to be in attendance for this meeting! Our club now has not one, but TWO operational remote telescopes! The Station 2 telescope is a 10" f/8 Ritchey-Cretien, and the Station 3 telescope is a 4" f/7 APO refractor. I have attached two pictures showing these telescopes. Hope to see you at the meeting, Myron RAC President (Myron Wasiuta) is inviting you to a scheduled Zoom meeting.
