For all you Dob owners and those without GoTo telescopes using Push To no tech, this is the non-encoder device you didn't know you needed. I learned about the PI Finder sometime last year. It's a small Raspberry PI or smaller device that can be purchased as a kit or even 3D print at home where you install all the electronics or as a completely finished device. It weighs less than a RACI (Right Angle Correct Image) Finder scope or about what a Tele Vue Delos weighs. It mounts in a finder saddle with an included dovetail. The device immediately impressed me. I'm looking forward to learning about Version 3 and why the kits are only at version 2.5. In a word, it's fantastic looking! The new version 3 is faster and like all Pi finders are encoderless! Fully assembled it goes from $485 - $535. The difference being on board battery or external 5V USB-C powered. In kit form the prices range from $15 for the unpopulated circuit boards to $65 for the 3D printed parts and so forth. The kit version builds the v.2.5 of the PI Finder. I'd go with the built version myself. It's still less than a Nexus fully loaded. Or the Tele Vue system. The encoder kit is less then $300 but the whole pod to install it with the encoders is nearly $2000. I like the Nexus DSC Pro. At $385, it's a decent device if you have the room to mount it. It is a one man shop in Australia. Solid product but right now there's no one that will take over for him. I asked him that question and he said he has 15 years before he can retire. The PiFinder is available in right hand, left hand, flat and straight through for refractors and SCTs with the eyepiece/focuser at the back. With this episode having the Founder speak about the product, it's an excellent opportunity to learn about the products and ask questions. That's always the best part of having a live speaker! I got to hear a presentation with the Nexus DSC developer at a club meeting in Hawaii. As the maker is in Australia it was the closest time zone for a talk! For me it started at midnight! The PiFinder website is here: PiFinder PiFinder PiFinder is an open-source, all-in-one telescope pointing solution. Works like digital setting circles, but without encoders or alignment using plate solving technology. Works with any scope, and mounts just like a finder! PIFinder is out of Sacramento, CA and ship everything via USPS Priority Mail 2 Day delivery. What's Up? Webcast: Richard Wolf-Jacobson, Founder of BBlabs/PiFinder What's Up? Webcast: Richard Wolf-Jacobson, Founder of BBlabs/PiFinder If you are still pushing any of your scopes to find an object and have considered an encoder system like Sky Commander (now retired and no longer available), this product is something to consider and I encourage you to attend live, Friday at 1 PM ET on the Sky-Watcher USA YouTube channel. John Sillasen, your gadget geek or as one member once called me, Inspector Gadget.

Can a member bring a camper to the Propbuster site to facilitate an overnight imaging session?

Reminder: TAAS Monthly meeting. When: Thursday, April 17, 2025 Organizer: Mark Strollo mark@... View Event Description:

As promised the event description to be posted to the general public is as follows. I plan to be there an hour in advance to set up for each event. I am planning on getting traffic cones from the town of Madison to block our observing area and we've had a club member volunteer for parking control. Please note the map link at the very bottom which will show the observing area /public and astronomer parking/ etc... The Shoreline Astronomical Society (SAS), a local 501(c)(3), has organized quarterly star parties at Salt Meadow Park (1362 Boston Post Road Madison, CT 06443), which are free and open to the public. People of all ages and backgrounds, including children, are welcome. Please join us for the opportunity to look through different types of telescopes, get hands-on experience using a club telescope, and discuss observing, telescopes, and all things astronomical. Some helpful notes to get the most from our Star Parties: Please join us early in the event if possible to avoid light from car headlights If you bring a flashlight, please bring a red light to preserve visual dark adaption Please leave your canine companions at home for this event; even well-behaved pups on a leash can sometimes get tangled in observing equipment/tripods/legs in the dark Bring your binoculars or telescope (we can help you figure out how to use your equipment if you need help) If it is cloudy or otherwise unfavorable for observing please check our social media accounts or our website (https://shorelineastronomicalsociety.blogspot.com/p/salt-meadow-public-star-parties-2025.html) for a weather cancellation up to 2 hours before the event. If the weather is ideal, please dress warmly, bring effective bug spray, and a warm drink Dates and Times as Follows Please RSVP via shorelineastronomicalsociety@... May 17th - 8:30-10:30 PM July 26th - 9:00-11:00 PM October 4th - 8:00 - 10:00 PM Map with Parking Area and Telescope Areas Delineated -- Jeff Dunn https://shorelineastronomicalsociety.blogspot.com/

Hi Folks, I am so sorry that I didn't send this invitation to you earlier. I hope a few of you can attend, but I understand that this talk announcement was sent very late. Anyway, here is the information. Talk title: “Monsters in the dark: searching for the origins of the most massive galaxies in our universe” Speaker: Dr. John Weaver, graduate of the Williams School 2013. Date: Wednesday, April 16. Refreshments: 4:15 - 4:30 p.m. Talk Time: 4:30p.m. Talk location: Fanning 111 Talk Description: Despite a century of observations, the origins of the most massive galaxies in the nearby universe remain elusive. Although much progress has been made, the details of their formation have been lost to time. Thankfully, telescopes are time machines, which means we can catch their progenitors in action in the distant, high-redshift universe. However, these galaxies are also extremely rare, forming in only the greatest collections of dark matter and cold gas. While this makes them ideal cosmological probes, observations capture only snapshots of different galaxies at different redshifts and cosmic epochs. Accurately piecing together this grand story therefore requires large statistical samples from the most sensitive infrared telescopes covering the widest areas. I will present our latest efforts to chart the formation and evolution of the most massive galaxies in our universe, taking us back to the first 500 million years after the Big Bang. I hope you can join us this afternoon! Best, Leslie -- Leslie F. Brown, Ph.D. Emeriti - Physics, Astronomy & Geophysics Connecticut College New London, CT USA

I attended the SAS meeting last night and have the following questions: 1. It was discussed that the Messier Marathon alternate date was Friday - 4/25. That is the same night as the Lyme Land Trust Observing event. Do we want to move the date to the 26th? 2. Who has the PST Solar Scope? SAS has an event on Sat 4/26 and I thought I would bring it (not that I want to be the holder of all of the club's scopes ;) ) 3. On Sat 5/17 the SAS club, in cooperation with the Town of Madison is doing a public outreach event at Salt Meadow Park in Madison. It would be great if the club could assist by bringing scopes to this inaugural event. Thoughts????

(sovera:announce) SoVerA Monthly Meeting April 8th 2025 Not sure if I remembered to send this to the group or not. It was a very long weekend not just working at NEAF but the horrendous drive back and forth in the rain at night with heavy traffic. Fortunately, its was 2 hours at best. An hour and a half in the morning so that's favorable. Tonight's SoVerA meeting will have a talk on "The Edge." The expansion of an Infinite Universe. The speaker is Erik Schmitt who you may recall spoke at our January meeting. He's quite talented and a very good speaker. The Zoom link is below and begins at 7 PM ET tonight! John Sillasen Subject: (sovera:announce) SoVerA Monthly Meeting April 8th 2025 Please join SoVerA on Tuesday April 8th at 7:00PM Eastern for a presentation by Erik Schmitt. This meeting will be virtual-only via zoom at https://zoom.us/j/94691230307. This month's talk is entitled "The "Edge" of an Infinite Universe which is Expanding?" We will walk through a series of thought experiments and discussion intended to provide some tools to effectively grapple with the topic and answer common questions such as "What is the Universe expanding into", "If the Universe is infinite how is it getting bigger", and "Is there an edge?" Erik Schmitt is currently serving as the treasurer of SoVerA. He previously taught physics and astronomy and was the director of the Perkin Observatory. ____________________________________________________________ Southern Vermont Astronomy Group (SoVerA) _._,_._,_

Anybody else see it late last night? Looks brighter than predicted Mag 2. Mag 1?

I found this accessible pdf guide to the Messier Marathon by objects by the hour. It was posted on Facebook and I renamed to give them proper credit for doing the work. The file name is MessierMarathonGuidebyUnistellar.pdf /g/TAASCT/files/MessierMarathonGuidebyUnistellar.pdf The link to the file is above. If you find it inaccessible it's likely that you never created a personal password to access /g/taasct. You can easily do that just go to and login. Ask for a password reset or create a password and you'll follow the bouncing ball..it's easy. John Sillasen
