Hi All,

We’d like to get a handle on the expected number of attendees.

If you are interested in attending and have not contacted me already, I would appreciate if you can email me please:

michael [at] astroshot [dot] com

Thanks.

Michael.

Ha!

It reminds me of my trip to Hoover Dam. On the way, there were signs for Hoover Dam Radio on an AM frequency.

So, we tuned in and it was just a prerecorded message on loop.

What was funny was the southern drawl accent saying:

“Hoover Dam. It’s Daammmmnn Big!”

😉

What exposure times did you use Bill?

How does one determine the start and end times of the meteor?

Regards,

Michael.

[Michael O’Connell]

Thanks Bill.

I’ve used Vega for calibration in RSpec previously when I used a Star Analyser in my telescope so I’ll stick with that method.

Thanks,

Michael.

[Michael O’Connell]

Bill,

How did you carry out your instrument correction?

I thin thinking of adjusting the settings in the camera to stack the images and use Vega as a standard reference.

Alternatively, I could try a sodium street lamp I guess.

Michael.

Schedule Update:

Jim Rowe will pop over to Dublin for the conference and will give a talk on SCAMP/FRIPON.

He will take my talk slot.

Regards,

Michael.

Hi Peter,

You’re more than welcome to attend!

I’m guessing the easiest route for you would be from Stansted with Ryanair? They’ve flights every couple of hours.

A few other BAA members have emailed me expressing an interest in attending.

If the flights were arriving at similar times, I could collect you all from the airport.

May I suggest that you email me please:   michael [at] astroshot [dot] com

We can then try and coordinate flight times.

At this stage, the venue is confirmed and speakers have booked their flights.

Regards,

Michael.

[Michael O’Connell]

Thanks Jeremy.

[Michael O’Connell]

Thanks Nick.

[Michael O’Connell]

Thanks Jack and Hugh.

Re the classification system, Bill Ward may be best placed to answer that question.

Bill: feel free to chime in here please if you see this post.

Hi Dave,

I was prepared for it. I registered with calsky.com and receive daily email alerts of satellites transiting the Sun and Moon.

Regards

Michael.

[Michael O’Connell]

Very nice capture Dave. Well done.

As it happens, I just visually observed the ISS carry out a similar solar transit.

The speed is phenomenal!

Michael.

Have you looked into installing Magic Lantern firmware add-on to the camera?

[Michael O’Connell]

Thanks Bill.

I was using a 1/2″ Watec 902 Supreme up to recently but in the past few weeks have upgraded to the 910HX and the increase in sensitivity is noticeable. Noticeable increase in the number of meteors for which I have recorded a spectrum.

I am also using a simple 500L/mm grating from eBay and a 6mm f0.75 lens – nice and fast yet with good optical quality.

Nice work Bill. I saw your YouTube clip before seeing this post and was wondering what NOVEX meant. 🙂

If Ni/Fe meteors suddenly appear at maximum brightness and then fade off, can we deduce anything beyond a low Ni/Fe content for meteors displaying the opposite of that?

[Michael O’Connell]

That’s interesting Marc. Must give that a go.

[Michael O’Connell]

Well done Nick and all the guys in updating the guide.

Good resource.

[Michael O’Connell]

Thanks Martin.

Would be interesting to put names to the people from the BAA, @ 5:22 in the video, who visited the telescope in 1997. I recognise a couple of the Irish people in attendance.

[Michael O’Connell]

Thanks Bill.

Im currently using a 500 Lines/mm grating. If I were to use say a 1,000 Lines/mm grating, would that help the spectrum resolution  and compensation for the shorter focal length lens?
