NSAS – Perseverance, Beginners Night in the Zoom Room, Solar Observing and BBQ at our new Field and Lesa Moore to talk to us about times and clocks!

Hi everyone

Well wasn’t that landing of Perseverance quite an amazing thing to watch. It all seemed so routine as it appeared to go like clockwork with no hitches at all. If you missed it here is the full 2.5hour broadcast but you can fast forward to the 1h 30min mark just before it enters Mars’ atmosphere.

We had our own broadcast this past week with our first Beginners Night in the Zoom Room with positive feedback from the attendees. The session was recorded so that they can re-watch the session and go over the material again to reinforce their learning. We will shortly be running another session so if you are a beginner, or just want to understand it a little more before diving in then this might be just right for you. If you wish to review the session then you can do so here. The password is Passcode: %t*Y1HVA. There is about 14mins of preamble before the session starts.

This month we also have held a members only Solar Viewing and BBQ at our new field in Terrey Hills. It is an impressive facility and when it is finally finished it will offer by far the best observing field in the Sydney metropolitan basin. With the rain and wet weather the ground works continued to be delayed and we will probably only be onsite after 30th June.

This month our speaker is Lesa Moore. Lesa holds a Bachelor of Science with Honors and a Masters of Philosophy, both specialising in Astronomy. Her talk on the 7:30pm,16th March general meeting will cover the tracking of date and time using astronomical clocks, as well as reviewing some history or the gregorian calendar and the development of the clock. It should be an interesting session. Zoom links are available on the NSAS webpage here.

I hope you are all keeping well.

Advanced Astrophotography Zoom meeting for Feb 2021

Join our zoom meeting on Tuesday 23rd February 2021 at 7:30 pm

I plan to talk about my 12v (nominal) Lithium Battery setup(s).

My suggestions on how to wire up a battery with some ideas that have worked for me (fuses, wiring, connectors and battery monitors).

This meeting is not targeted at beginners but beginners are very welcome.

While I focus on Lithium Iron Phosphate (LiFePO4) batteries, the same wiring info can apply to Lead Acid batteries (eg. AGM, Gel etc).

Warning – I plan to include a couple of simple formulas but hopefully not enough to put you to sleep.

If you are not a practical person and can not build you own battery setup (or persuade a friend to do it), then the meeting might still arm you with information to help you decide on your own purchase decision.


If you want to think about your own battery setup and bring a question to our meeting, think about how much power you use over a night. (particularly in the middle of winter, in high humidity with your dew controllers running or on a hot summer night with your astro camera trying to maintain your minus something degrees sensor temperature while constantly slewing to image different targets)

— specification sheets or just get some meters and measure the current.

NSAS Speaker for February, New Zoom sessions for Beginners, New Members Information Pack and Monthly Showcase inundated

Hi everyone

Welcome to 2021 and the start of our General Meeting speaker series. We have a great lineup of speakers for this year covering a range of topics including; Radio astronomy, Space Archeology, the latest research using ASKAP, the Juno mission to Jupiter and quite a number of other interesting topics. We’ve got more Doctors, Professors, Associate Professors and luminaries organised than you can poke a stick at!! These sessions are open for members and visitors via Zoom – please use this link: here*. Our next speaker is Professor Ray Norris from CSIRO and the Western Sydney University who will talk about the latest discoveries from the $185M ASKAP telescope. The session is on at 7:30pm Tuesday 16th February so mark this into your diary now as it is sure to be interesting. Zoom links are also available in the calendar on the NSAS Website.

We are pleased to also announce new Beginner Zoom sessions to accompany the Beginners Night in the Field. These zoom meetings and walkthroughs will help people new to astronomy get going and understand the basics required to get a scope setup and pointed in the right direction. These sessions will be run by Igor Hodoba, a senior and experienced member of the club who has been involved and owned many telescopes over the years. These 2hr sessions are part of a new curriculum which will be discussed in greater depth at the next general meeting on the 16th February. If you are interested in getting involved in Astronomy then we suggest that these zoom sessions, along with the Beginners Night in the Field, is a great place to start your journey. To register for this event that will be held at 7:30pm, Wednesday 24th February please click here.

The Membership Officers have been busily working on the Membership pack and updating this for 2021. This pack is available to members only and will be distributed shortly under separate email to current financial members.

And lastly, I understand that the January holiday period, which is meant to be a slow time for astronomy, due to the longer days with shorter hotter nights, seems to have shrugged off this label and we have a large number of submissions for this month. These will be shortly posted by Ben up on the society’s Facebook and webpages so be sure to take a look. Hope you are keeping well..
