Dave Bennett – In Memorium

Posted by as In Memoriam

David G. Bennett 1949 – 2022

Dave Bennett ready for the public at the Centre of the Universe - 2013
Dave Bennett ready for the public at the Centre of the Universe – 2013

Dave Bennett was diagnosed with leukemia about a year ago. On Monday afternoon this week, he passed away peacefully at home.

Dave was a member of the Victoria Centre where he was active in education and public outreach for many years.

His family, extended family and his many friends will miss his humour, his kindness and his enthusiasm for whatever activity he undertook.

Following his wishes, his body will be given a green burial in the Royal Oak Burial Grounds. No flowers, please (allergies). In lieu of flowers please donate to the BC Cancer Foundation or the Saanich Peninsula Hospital & Healthcare Foundation.

The obituary will be available at Care Funeral in a couple of days.

There will not be a Service, but please raise a glass of your favourite tipple and drink a toast to his memory.

Memories of Dave from members

This is so sad to hear. Dave was such an advocate for public outreach. I have missed him at outreach events such as the Saanich Fair and as a prominent Astronomer in the parking lot for Saturday nights at the DAO. What a loss for our community. I will be certainly thinking of Susan and his family at this time.

Lauri Roche

I’m very sad to hear this news. Dave was one of many RASC members who encouraged me to be active in public outreach activities at the DAO and to pursue my interests. He was a kind, generous man.

Matt Watson

I’m so sad to hear this. I still remember our little adventure of recording the asteroid occultation of 1263 Varsavia on July 18th 2003. I still remember being so pleased that we actually picked the right star and that it blinked out at approximately the predicted time. I have to admit it was David’s excellent starhopping skills as neither of us had goto systems. He will be missed.

David Lee

It is really sad to hear the news.  Dave and I [spent] many happy times doing the public outreach.  When needed he was always there.

Sid Sidhu

I remember Dave’s dry sense of humour the most, but also his willingness to evangelize astronomy at any and all public events. Despite professing to be a “grouch”, he was great with the younger generations interested in astronomy, challenging them to dive in. Dave was also a dedicated observer and one of the first Victoria Centre members who welcomed me to the group – thanks Dave. I certainly will raise a glass to Dave’s memory, and celebrate his contributions to amateur astronomy through RASC.

Joe Carr

Wow this sucks. He’s been one of the members who I’ve wondered where they’ve gone. Sadly now it’s permanent. He thought he presented as a grump but always had a kind manner. Will remember him with that big blue refractor. Needs to be said, F… Cancer.

Bill Weir

This is very sad.  Dave was a member when I joined.  He me feel good to be part of the group.

John McDonald

Very sad news, indeed. Dave was an immediately likeable fellow, whose immense astronomical knowledge and infectious enthusiasm was appreciated equally by his RASC colleagues, and the public.  Dave will be deeply missed, and fondly remembered.

Sherry Buttnor

I remember some great conversations with Dave at outreach events and particularly at the Halifax GA (2015). Dave was a proud member of RASD and was Dave XXII. He will be missed.

Chris Purse

Dave was an active, very friendly, welcoming member of our Centre. Betty and I enjoyed interacting with him at meetings and outreach events.  We often saw Dave and Susan at Victoria Symphony concerts, too. We are very saddened at his passing.

Jim & Betty Hesser

Sorry for your loss Victoria Centre. Condolences to the family.

Kim Hay

I’ve known Dave Bennett for most of my time in the Victoria Centre, and more recently when we lived near each other on the north end of the Saanich Peninsula. I greatly regret the press of time conflicts, work obligations and finally the pandemic that limited the time I had with Dave and Sue in recent years. Like other members of the Victoria Centre, I have many memories of Dave’s participation in our outreach activities, especially a trip that we took with Sid to a school on Saltspring Island several years ago. His love for astronomy, sense of humour and friendly manner were always front and centre at these events and at other Victoria Centre activities. I’m glad I knew him and I will miss him.

President’s Message – October 2022

Posted by as President's Message

It has been five years since the astronomy bug caught me big. After the August 21, 2017 solar eclipse, I started looking for a telescope to replace my old Tasco refractor. I was close to buying a used C8 Schmidt Cassegrain, but couldn’t figure out how I could fit it in my house (or life). My first “new” telescope was an adequate little Newtonian, and since then I have acquired many telescopes, mounts, and accessories; never spending more than $150 at a time, to make a Frankenscope that works for me.

During that exciting autumn of 2017, I met Lauri Roche at a science outreach event and she invited me to give a talk at the RASC Victoria Centre Astro Cafe about a “gizmo” I developed for my telescope. Soon after, I joined the Society and made friends with many of you at Astro Cafe. With the Pandemic, our online events became important social activities for me. We’ve been doing outreach and in-reach events together. We have been a wonderful supportive community, which I now treasure.

In the autumn of 2020, our then president, Reg Dunkley, sent out a desperate plea for new council members, and in particular somebody who would step up to be our next president. I felt I was still a newbie, but the community was important to me and I did step up. I’ve been having a wonderful time working with this group, and I’m looking forward to many more roles I can take to keep our programs going and growing. But I am approaching the end of my second year as president and according to our bylaws, we need a new person to put their name forward as president. We have several other Council positions to fill as well.

So here is my plea – my desperate plea: please volunteer for our council! The roles are not onerous and we have a strong volunteer base to get things done. The past executives are all very helpful and supportive, so no one needs to feel they are all alone. But our society cannot function without people in the key positions and I know there are several of you reading this not thinking that you could be one of them. You can.

You should directly contact Reg, who as Past-President (pastpres@victoria.rasc.ca) is in charge of council nominations. But we know that few people ever volunteer on their own initiative. Please don’t be surprised or unhappy if you get a call from one of us. We need you. We appreciate you. We’ll have fun with you!

Look Up,
Randy Enkin, President@Victoria.RASC.ca
