- The following is the original text of this interview -
zwo：First of all, congratulations on winning the asiweek championship. Can you tell us a little bit about yourself?
antoine grelin：Thanks, my name is Antoine Grelin, I live with my wife Dalia in Las Vegas, Nevada, and on youtube we created a channel called "Galactic Hunter" and posted some content about astrophotography.
zwo：In addition to astrophotography, are you actively involved in other astronomy-related activities? antoine grelin：I'm a member of the Las Vegas Astronomical Society, and I often attend conferences and special events, so I have a lot of opportunities to make astronomical observations with different types of telescopes, as well as meet local amateur astronomers and astrophotographers. zwo：What is the air quality in your area? What about astrophotography that you usually do in **? antoine grelin：We live in Las Vegas, which has a level 9 in Porter and is very light polluted. We used to drive an hour to the perimeter of Porter Level 3 every clear night, but now we all do narrowband imaging near our homes and only go to the periphery when shooting broadband**. One good thing about Las Vegas, though, is that the skies are very clear most of the time, and despite the strong light pollution, it's surrounded by desert areas, so you can have beautiful dark nights no matter what direction you drive for an hour or so. zwo：Can you tell us about the awards**? antoine grelin：This was my first attempt at 2x2 mosaic stitching and I had never tried stitching before (except for my comet + Mars image, but that was only 1x1 so it was very easy to stitch). After more than 8 years of astrophotography, it's finally time to try mosaic stitching! The target was the Rho Ophiuchi molecular cloud complex in the constellation Ophiuchus, which I spent about 2-3 hours on each, adding together for a total of about 10 hours. 
antoine grelin：And the timing of this attempt is very good, because JWST posted a photo of Rho Ophiuchi** the day before I posted **, which was just right to mark the location of JWST's shooting on mine**, which is very honorable. 
zwo：What equipment do you use? Do you have them? antoine grelin：My equipment is: RASA 8, ZWO ASI2600MC Pro camera, equatorial mount is 10micron GM1000HPS, computer is Primaluce Lab Eagle 5s, shot at the Utah Desert Remote Observatory at Potel Level 2, I feel that the RASA of F2 is a match made in heaven with the Level 2 zone. 
zwo：How do you typically do post-processing? Would you like to share your process with us? antoine grelin：My entire process was handled with pixinsight, where I did all the calibration and stacking with batch pre-processing and then started processing the images. Start with background extraction and then work with blurxterminator and noisexterminator, don't go too far. Then I do the color calibration, stretch the image, remove the stars, and let the starless ** show as much detail as possible, and then after enhancing the image to the best state, I will use pixelmath to re-add the stars and reduce their size a bit to avoid being too obtrusive. zwo：Can you share with us some of your favorite shoots**? antoine grelin：Of course! 
zwo：Can you share some memorable stories from your time in astrophotography? antoine grelin：A few years ago, Dalia and I were in the desert, when there was no cell phone signal and internet, we were in the middle of nowhere, and during the shooting, we saw a bright light rise into the sky (this was before the Space-X era, so there were very few rocket launches, and we had absolutely no idea what it was). The bright light parted high in the sky, and then, **, a huge blue cloud formed in the distance, which stayed in the sky for 30 minutes before dissipating. It turned out to be a missile test launch conducted by the U.S. Navy, which was a very shocking spectacle, and we didn't have the internet at the time, so we couldn't check out social ** or news, unlike rocket launches that happen so often now. 
zwo：We know that you created "Galactic Hunter" with your wife, what is it like to work in astrophotography with your family? Have you encountered any difficulties? antoine grelin：It feels good! Especially when I first started shooting in the desert with no signal, even if you can look up at the stars and enjoy the moment, but shooting alone for a few hours is very boring, and it becomes fun to be with my wife. The difficulty was not related to astrophotography, but to record in the desert at night**, and you needed to find the motivation to keep shooting. 
zwo：From a hobby to a professional astrophotographer, how has astrophotography influenced you? antoine grelin：I'm happy to be able to quit my job and work full-time in astrophotography, and it's more stressful that everything is unstable because you never know how much you're going to earn next month, there are good times and bad times, but you never know. My wife has also joined me full-time this year, and we're more productive together with more free time to produce more content. zwo：What do you think are your highlights in astrophotography? antoine grelin：There are several. One was winning the AAPOD2 Award of the Year in 2021, and the first interview with Orion Telescopes in 2016 meant a lot to us. 
antoine grelin：And then this time I won the championship at asiweek, and the work was great! Another highlight is the ability to ** rocket launches with members of NASA, thanks to the content we have released. But the ultimate highlight hasn't happened yet, and that's when we finally get the APOD, which obviously will never happen.
zwo：When did you start using ZWO's products and do you have any advice for us? antoine grelin：When I first upgraded my equipment, I started using ZWO products. I upgraded directly from a DSLR to a ZWO ASI1600MC camera, which was a huge leap. I quickly bought the AsiaIR and ZWO guide cameras to use with the cameras, and I fell in love with ZWO products at that time.
For the advice, considering that everything is already so good, it is difficult to find anything to say, but I hope to see in the future:
1.a high-end equatorial mount with cable management;
2.A portable Hoshino equatorial mount that is lighter and smaller than ever before.
