Discovery Astrophotography with ZWO ASTRO

Astrophotographer’s Story: Kevin Parker

Hello Kevin,thanks for accepting our interview invitation. Congratulations on winning the ASIWEEK competition in week #41/2024!

Q1:At first, congratulation that your nice image won #ASIWEEK. Can you introduce yourself to us? 

Hello and thank you. I’m Kevin. I’ve been into astronomy since I was 10 (now 61) as a lifelong hobby. I grew up on a farm in Bortle 2 skies where the stars were so bright. At age 10 my parents gave me a telescope for my birthday, a little 60mm refractor which started the ball rolling. At about age 13 I met an old man (Joe) that ground telescope mirrors. He made me an 8 inch F7.5 mirror and telescope. While I didn’t catch the telescope making bug at the time, it would a number of years later when I used his mirror grinding books to make several mirrors of my own, the biggest being a 16”.

Q2: When did you start astrophotography and how?

I started astrophotography in the early 1980’s using film. I had a darkroom and would develop and print my own pictures. This was mostly black and white but I would also develop colour slide film. I started out with piggyback telephoto lenses on an old EQ mount with manual tracking and over time progressed to shooting through the main scope. This was hard on the neck at times while eyeballing a guide star in a reticle eyepiece for an hour at a time!

Q3: Why do you love astronomy? What does it mean to you?

Apart from the amazing beauty of the universe, I like to know our place in it, however small. Every time I image a galaxy or dense star field, I speculate how much life must be there, and how fascinating it must be. Astronomy is my “Star Trek”.

Q4: Can you tell us about the winning photo

NGC6302 the Bug or Butterfly Nebula, a very pretty planetary nebula in Scorpius. I have neglected planetary nebula up to now since they are so small and I don’t have a long focal length scope to capture them in the traditional manner, long focal length SCT etc. So I thought, why not try a more regular scope, and one of ZWO’s new planetary cameras with small pixels. The idea worked. The ASI 678mc and ASI 715mc match well with my 12” F5 Newtonian for small DSO’s – planetary nebula, small clusters and galaxies. 

The Bug – Butterfly Nebula. 2 hours 36 minutes of 1096 frames, 12″ F5 Newtonian, ZWO ASI715mc, SV220 filter.
Messier 83 galaxy, 1 hour 52 minutes, ZWO ASI678mc.

Q5: What gear do you use? Any pictures of them?

I have a few different telescopes, but my main primary scope is a 12” F5 Newtonian on a rather overloaded, modified Skywatcher NEQ6 Pro. This is all housed in a roll off roof observatory I built in 2016 in the back yard.  I do astrophotography on a tight budget. I don’t have all the latest accessories. I make some adapters out of wood. My computers are 10+ years old. There is very little automation. I often sit with the scope as the images come through.

Q6: You seem to be skilled in both deep sky photography and planetary photography, which one do you prefer? Any experiences you can share?

I started off doing deep sky. Planetary is fairly recent from about 2018 onward. I like both equally even though the capture and processing methods for each are very different. With small DSO’s and planets, the equipment is actually the same! This is very convenient.

Q7: How is the air quality in your region? Where do you normally take astrophotos?


In my backyard from Mackay Australia. I live on a largish block, about 30 metres wide by 130 metres long. It’s about Bortle 6, roughly. I have a contrast of bushland at the back, with the city and lots of streetlights and traffic at the front. Since I live in the tropics, summer is mostly cloudy with winter being the time for astronomy.

Q8: Astrophotography has a long learning curve, what difficulty have you encountered along the way? How did you overcome it?

I just take it slow! That was the only way in the film days anyway. I’m no expert, never will be!

 

Q9: Is there any memorable story you can share with us from your astrophotography days?

Comets. Used to chase as many as I could, my first being comet Halley. I followed Halley for over a year back in 1985 – 1986. My three most memorable comets being Halley, Hyakutake and Hale – Bopp, all beautiful naked eye comets.

Q10: How do you think the field of astrophotography has changed in recent years?
Growing up through film days, I have seen a massive explosion of technology in both hardware and software. Every year it gets better with lower noise, higher resolution cameras, more capable software and more highly developed filters for shooting specific objects. All this available to amateurs that now rival observatory photos of just a few years ago. It’s changing so fast it’s quite hard to keep up with!

Q11: How many ZWO products do you have, what’s your first ASI camera?

I have 3 ZWO cameras, an ASI 183mm Pro, ASI 678mc and ASI 715mc, plus some adapters. The ASI 183mm Pro was my first ZWO camera that I purchased in 2018.

Q12: Would you mind sharing with us your upcoming shooting plans?

Well, I take it on a night by night basis, depending on weather. But I plan to explore shooting more planetary nebula, small clusters and galaxies with the ZWO planet cameras and 12” F5 Newtonian. Oh, and the planets too. I’ve actually done more deep sky with the planet cams than planet imaging this year. That may change as Jupiter and Saturn rise at a more acceptable hour. I’m not much good after midnight these days. 😉
