What other equipment will we need on our astronomy observation nights?
If you have been following this blog you will know that
Steve has just taken up astronomy and is awaiting the arrival of his new
telescope. He has written previous blog posts about his new learning journey
and these can be found here: https://wherenexthun.blogspot.com/2021/01/buying-your-first-telescope-what-do-you.html https://wherenexthun.blogspot.com/2021/01/a-beginners-guide-to-telescope-mounts.html and https://wherenexthun.blogspot.com/2021/01/a-beginners-guide-on-understanding-how.html
In this post he takes a look at what additional equipment
he thinks he needs to take with him on his first astronomy viewing night.
I am getting really excited and over the last few weeks
I’ve been doing lots of reading, both on the internet and from books. I am
trying to get to grips with several things all at once:
·
what other
equipment I might need on the night?
·
how to set up
the telescope when it arrives?
·
how to plan my
first astronomy session?
Equipment wise, apart from the telescope, eyepieces,
tripod, Alt-Az mount and Barlow lens, here is a list of the other things I
think I need to take with me:
1.
‘Turn-left-at-Orion’
– my astronomy observing guide book, some star charts relevant to the evening,
a planisphere and my astronomy recording diary/notebook
2.
a red-light
torch – so I can read things without ruining my night time vision. I have a
head torch with a red light on it as well but it is a little hit and miss
selecting it
3.
a normal white
light head torch for clear up
4.
apps on my
phone – Stellarium and Sky Safari; Nightshift (gives me the viewing conditions
each night), Clear Outside (ditto), Moon Phase calculator, ISS tracker
5.
picnic blanket
to put beneath tripod to catch anything I accidently drop
6.
binoculars –
I’m getting a 10 x 50 pair but haven’t decided which ones yet. Great for
viewing constellations, finding objects, panning the milky way, observing the
moon and whatever else I can think of on the night
7.
a small
toolkit for on-the-spot adjustments
8.
a bubble
spirit level to make sure the tripod is set level
9.
camera lens/telescope
cleaning kit
10.my camera bag (containing my DSLR, its tripod, my wide
angle 24mm lens, my 18 – 55mm lens, an intervalometer, my GoPro Hero 9 and
various batteries, memory cards etc)
11.a comfy chair and a small folding aluminium table
12.portable power pack for my smartphone
13.snacks and hot drinks
14.clothing – additional spare layers for head, hands, torso.
I’ll be wearing thermals and other mid and outer layers!
I will also be taking the following which relates to my
particular telescope, the Star Discovery 150i WIFI.
·
A lynx astro
silicone power cable for the sky-watcher mount (cigarette plug 2m version)
·
A
Sky-watcher/celestron powertank 7Ah to power the mount and charge up phones etc
·
Spare AA
batteries for the mount
·
Astro
essentials ND96-0.9 1.25” moon filter
·
Astro
essentials Canon EOS T ring
·
A Celestron 81055 NexYZ Universal
Smartphone Adapter because sometimes I will just want to capture images with my
smartphone rather than the DSLR
·
Some form of
protective carry case. I haven’t yet decided on what type but I might well try
and make my own custom fit one using waterproof tent material, close cell foam
sleeping matt and Velcro. It will hold the optical tube assembly (OTA) and
eyepieces. The Mount and tripod will store in another bag. I have a large 100
litre waterproof roll down bag which I used to use for sailing trips. It is big
enough to hold the mount and tripod plus most of the other accessories
mentioned above.
·
Optional – a
dew shield that acts as an extension of the main optical tube assembly. I don’t
know whether to get one so I am on ‘wait and see’ mode
·
Optional - a
cover for the telescope. I will be setting it up during daylight when out with
the motorhome and a weatherproof cover would prevent dust etc getting in to it
before I started the night time observing session. (I suspect I
will try and make one at home).
·
For any
astrophotography sessions – a white T shirt to get my 20 – 50 ‘flat frames’. (It’s
complicated and I am only just starting to read about astrophotography. Along
with the actual images you take you also need to get dark frames, flat frames
and bias frames. I’ll explain these in a later post when I have got my head
around it all. But, for getting flat frames you need a white t shirt to put
over your lens or telescope).
I hope that this series of posts
has helped if you are thinking of taking up astronomy. They sort of chart my
understanding from knowing nothing to this point now. Over the next few weeks, I
am immersing myself in reading and finding out about landscape astrophotography
and also about how to get to grips with my new telescope and the SynScan
programme that comes with it.
In the meantime, I hope you are all
safe and well and planning good motorhome jaunts for when lock down is lifted.
Take care, stay safe.
Steve
