Learn how we can largely reverse these negative effects by taking simple actions so future generations don’t pay for our mistakes.

Dr. Ariel Graykowski

The Prevalence of the Unistellar Network in the Growing field of Citizen Astronomy


Ariel is a Postdoctoral Fellow at the SETI institute focused on astronomy of small bodies. She is also the lead of Unistellar's comet program and conducts all her research in collaboration with citizen scientists. She graduated with her PhD in geophysics and space physics from UCLA's EPSS


department, where she studied the properties of the irregular satellites of the giant planets as well as fragmenting comets. Before that, she received her undergraduate degree in physics with an emphasis in astrophysics from UC Davis.

Talk Description: The Prevalence of the Unistellar Network in the Growing field of Citizen Astronomy

Unistellar is a smart telescope company partnered with the SETI Institute to establish joint research and education programs aimed at developing a citizen scientist network of Unistellar astronomers. Through this collaboration, SETI astronomers lead five citizen-driven science campaigns on asteroids, exoplanets, cosmic cataclysmic, planetary defense, and comets. The Unistellar Network is comprised of citizen astronomers around the world and has grown significantly since the citizen science program began in 2021. Over the last year alone, the number of registered citizen astronomers has doubled to over 2,000. The Network is comprised of eVscope models with 114 mm diameter apertures (eVscope 1, eVscope 2, eQuinox 1, and eQuinox 2) and most recently 85 mm
(ODYSSEY). We will discuss how results from the ODYSSEY compare with results from previous models. Preliminary tests show that photometric results are statistically consistent between all models. We will discuss some of the most recent achievements of Unistellar's citizen science campaigns such as the observation of supernova SN 2023ixf in the Pinwheel Galaxy by 123 citizen astronomers over a 35 day period. Sgro et al. (2023) found that the measured peak absolute magnitude of M = -18.18 ± 0.09 impressively agreed with results from meter-class telescopes (e.g., Jacobson-Galan et al. 2023). In the comet program, the Unistellar Network has been vital to observe comet outbursts. The eVscopes can detect comets as faint as apparent magnitude Gaia G of 16.8 mag, which allows for very thorough monitoring of a comet's activity along the course of its orbit
(Graykowski et al. 2024). The exoplanet program has recently showcased the facilitation of citizen astronomers into peer-reviewed science when 16 high school students utilized eVscopes to help confirm the existence of exoplanet TIC 139270665 b. All 16 students are co-authors on the paper (Peluso et al, accepted for publication in AJ). These achievements and more exhibit the increasing prevalence of the Unistellar Network in astronomical research, as well as the need for citizen science in general to accomplish the science goals in many fields of astronomy.

Talk Description: From Astro imaging to Exoplanet Science: Same Gear,

New Excitement

For those of us who have been doing deep sky and planetary imaging, there is nothing like the satisfaction of using our observing skills to create a beautiful picture. However, what if the same equipment and some of the same attributes used to create such wonderous pictures could also be used to detect a planet transiting a distant star? And what if, as an additional bonus, that same experience resulted in advancing scientific research into that exoplanet?
Those of us who have transitioned from deep ski astro and planetary imaging to exoplanet observing no doubt remember the thrill of our first exoplanet detection. We also experienced how easy that transition was since the same scope, mount, and imaging camera were used.
This talk will present how astro-imagers can use their exiting gear and observing skills when transitioning to exoplanet observing. An example of an actual exoplanet observing session will demonstrate the use of the (free) software available to aid in exoplanet analysis. Finally, the contributions that amateur astronomers can and are making to exoplanet science will be highlighted.

TALK TITLE #1: Using action cameras/360 degree cameras and mobile phones for astrophotography/time lapse

Covid 19 and how it has affected the industry and how welI do things differently

Gordon Hayes is a retired psychiatric nurse (age 63), he is a coffee and malt whisky
connoisseur and dog lover.  He has been interested in astronomy, particularly the
astrophotography side for a number of years and until 2017 he did
mainly narrowband imaging with the occasional LRGB image from his back garden in Hereford, UK.  His partner Joanna and three boys (Floyd, Forrest and Fenn) moved to
Harrogate, North Yorkshire in late 2017 and due to this change of location deep sky imaging was no longer possible from where he now lives (lack of space and overhead wires). While still in Hereford, he started dabbling with time lapse astrophotography using a DSLR and a motorised camera slider, this now occupies his astrophotography sessions which also incorporates star trail images, animated star trails videos, nightscapes and “Holy Grail” time lapse sequences.  More, recently he changed his mode of transport for overnight time lapse trips and no longer uses public transport, instead he now uses a recumbent trike and trailer (more on this in his talks). He has had the
honor of doing several talks and workshops at NEAIC in the past few years and feels that it is always a great 
place to share ideas and knowledge and learn from others.

TALK TITLE #1: Using action cameras/360 degree cameras and mobile phones for
astrophotography/time lapse

Gordon originally bought a 360-degree camera to help document rides on his recumbent trike but he has found that they are far more versatile than just that, this talk will look at the astrophotography capabilities of these cameras including some of the special 360 effects that can be used. Also over recent years mobile phones and their camera technology has taken off “astronomically”, He will look at some of these capabilities on a typical mobile phone.

Covid 19 and how it has affected the industry and how welI do things differently
: Everybody was affected one way or the other by the Covid pandemic with lockdowns, shops not being able to open, essential travel, etc. This talk will look at how some people adapted and changed, he will also be talking about how this and other circumstances forced him to change the way he does remote time lapse trips and how his completely new website came about.

Talk Title: Getting Lucky 

Lucky Imaging is a technique where rapid short exposures are used to “beat the seeing” for very bright astronomical targets such as the Sun, Moon, and Planets. Advances in camera and processing technologies are also bringing this technique in a more limited way to deep sky imaging, as evidenced by a recent tidal wave of products that capitalize on the idea of “live stacking”, which is really just a variation of the techniques used by
lucky imagers for years. In this talk Richard will review the current state of the art for lucky imaging for all types of astrophotography, its challenges, and a few predictions about where things are going next.

Fireballs Aotearoa


Simon Lewis is an active Astro photographer located near Christchurch, New Zealand. He has been active in the hobby since being introduced to it by his uncle at an early age when living in Europe. He grew his interest further while living in

the north of Scotland in the 80-90s taking an interest in auroral research and meteor detection in the VHF radio spectrum.


After moving to New Zealand in 2008, Simon continued his interest in radio astronomy doing moon bounce experiments in the VHF-Microwave spectrum. With access to the dark skies of New Zealand he built his own ROR observatory and grew an interest in imaging emission and dark nebulae and supernova

Simon works in telecommunications professionally working for a national telecommunication provider in New Zealand. In his spare time, he is also the current President of the Canterbury Astronomical Society where he provides management of the societies education and outreach programmers and is also a member of ZWO technical support team providing end user support and product support to the internal ZWO team.

Talk Title: Fireballs Aotearoa: Hunting Meteors in the Southern Hemisphere
Of nine rare meteorites that have been found in New Zealand, only one was seen to fall, and that was way back in 1908. In 2004 a meteorite came through the roof of an Auckland house during daylight, but the fireball wasn’t seen. Fireballs Aotearoa was established in February 2022 to change that. Using cheap video cameras and low cost compute modules, New Zealanders from schools, universities, observatories and their own homes, are watching the night skies for incoming meteorites, ready to calculate where those elusive rocks might be found.
Simon Lewis takes us through how citizen science is contributing to the search for these elusive New Zealand meteorites but also playing an important role in the discovery of previously unknown meteor showers and helping us discover more about these galactic wanderers.  Simon will show how you can also build your own low cost meteor camera using easy to buy parts and prepackaged software so you too can build your own meteor observatory and join in and chase the burn.

As the creative designer and head of product development, Tim led SoftWriters to become the largest supplier of software to the LTC pharmacy space in the US. Tim retired from SWI in 2018 after serving as the CEO for 18 years. Always an avid photographer, Tim looked for a new challenge in the area of astrophotography. He designed and built a completely automated backyard observatory, as well as automating another astroimaging setup at the Sierra Remote Observatories. Tim developed an imaging scheduler application that completely automates target selection and acquisition, making the collection of data a completely automated operation. Tim concentrates primarily on photographing deep space objects, as well as solar imaging. He is a regular on The Astro Imaging Channel where he also is a frequent presenter. Tim lives in Pittsburgh, PA with his wife and 2 sons.

Talk Description: Typically, narrow band images of nebulae are combined using a mapped palette that, while striking, does not reflect the natural look of emission nebulae. In this session, Tim will explore the true “color” of emission nebulae, and discuss how those colors can be represented using computer monitors and printers. Tim will then demonstrate a technique for combining images that takes advantage of that “more natural” color mapping using both PixInsight and PhotoShop.

Easy Science with the Spectra of Stars.


Tom Field was a Contributing Editor at Sky & Telescope Magazine for ten years. He’s the founder of Field Tested Systems and the author of the RSpec software ( which received the S&T “Hot Product” award. A pioneer in

amateur astronomical spectroscopy, Tom promises to demystify the field and open the door for you to do easy hands-on the field and open the door for you to do easy hands-on science.

Talk Description: Do you want to do some hands-on science with your current equipment? Do you want to learn more about the HR diagram and the lifecycle of stars? Are you looking for a way to augment your imaging activities, especially under light-polluted skies?
In this session, you’ll learn how easy and inexpensive it is to capture star spectra using a simple 1.25" filter grating. You don't need dark skies. You don't need a Ph.D. in astrophysics or a lot of math! And there's no steep learning curve.
We'll start by discussing a bit of the history and science of spectroscopy. You'll gain an understanding of why spectroscopy is so powerful. You’ll see why spectroscopy is the primary research tool we use to understand the stars.
Then we'll review a handful of simple sample spectra captured with standalone DSLRs or small (3" and above) telescopes. We'll look at the spectrum of a supernova and of a black hole. We'll examine how to detect the atmosphere of a planet, and how you can use spectra to detect the composition and temperature and radial velocity of stars. You'll learn how to extract exciting scientific data from spectra you can capture on your first night out.
We'll finish up by talking about how you can get started in the field, what targets to begin with, and where to find resources on the web. You’ll also see how you can do citizen science by contributing spectra to the AAVSO spectra database.
Astronomical spectroscopy isn't just for professionals! Join the thousands of amateurs who are using spectra to learn the details behind the images we capture.
