  1. Thank you alacant! Your photograph looks great! Is that a dark nebula near the comet? Sadly, no more comet hunting for me! Clouds are back, and I'll be flying back to a Bortle 999 location soon for Christmas But I had a chance to photograph 46P, and here is the result And indeed, 30 seconds seems to work well for comets! Thanks everyone for your suggestions!

    46P/Wirtanen, my first comet!

    Thanks! Indeed, not easy to process at all, and I kind of felt like MacGyver during post-processing... I guess I'll come back to that picture some day, when I acquire better processing skills! For the record, the video wasn't meant to be part of the challenge, but more to illustrate the main image. I'll add that to my original post to avoid confusion. Thanks!
  3. Thanks a lot! It's ~60x30s, so half about an hour! Nice pic by the way. Not always easy to have a perfect focus, especially in the cold and sometimes in exotic body positions
  4. Hello! The sky finally cleared up Saturday, after weeks of clouds... And luckily, right when 46P was the closest to Earth! So I had an opportunity to photograph my first comet I wasn't really sure what lens was the most convenient, so I settled on a 55-200mm zoom lens, attached to my Fujifilm X-T1. It gave me flexibility in the framing, to include both 46P and the Pleiades. The weather in Munich was quite cold, around -5°C, and slightly windy. Good for the noise, less for myself! The post processing was quite difficult... I had to deal with a lot of light pollution, and I'm still not very comfortable with it. Stacking was also complicated, I tried a few different settings in DSS, but non was 100% perfect. I ended up using a first stack for the comet, which I inserted into a 2nd stack of the stars and DSO. The result is okay, but I think it can be better. Alas, it's just processing skills & techniques which I am lacking. So, I consider this a first version, and I'll have another go at it in the future, when I'm more comfortable with post-processing Exif: 40x30s, ISO 1600, 150mm @ f/5.6 Gear used: Fuji X-1, 55-200mm and iOptron SkyGuider Pro Post-processing: DeekSkyStacker, Photoshop & Lightroom Location: Munich city center (Bortle 6/7) ----- Here is a short timelapse I did with all my exposures (about 30 minutes). It's not part of the challenge, just an illustration of the main image 46P-Wirtanen.mp4
  5. I worked on a quick timelapse of 46P flying near the Pleiades, I'm rather happy with the result Even though the lens I use has heavy vignetting, and some kind of white ring is showing. I don't know where this comes from, as it's not on all the frames. Perhaps a flare of some kind?
  6. My pleasure! I also had a go at it yesterday evening, and did a quick and dirty stacking in DSS, but it's not so great I'll have to study comet stacking!
  7. Not silly at all! I use this website to know about astronomical events: https://www.timeanddate.com/astronomy/sights-to-see.html It's a great tool, especially for eclipses, because it shows you what the eclipse will look like (depending on your location). Then, I just add the event to my personal agenda. There's also a page dedicated to planets, to help you know when they are visible. Basically, check out the "Sun & Moon" menu at the top, it's full of interesting tools! Regarding comets specifically, there's also this dedicated website: http://www.cometwatch.co.uk/bright-comets-of-2018/

    Stellarium - adding comets

    Louise, I have the same result from Glasgow, yesterday at 6pm, both from Stellarium desktop and Stellarium web. I have no idea if that is the actual position of the comet, but since Stellarium Web doesn't require any extra configuration to show 46P, I assume that it's the correct position As for the clouds, it seems that we share the same weather... Good luck, hopefully the sky will clear up for you! Pierre

    Stellarium - adding comets

    Hi Louise, Here is what I did for 46P: Go to: Configuration Window > Plugins > Solar System Editor Click on "Configure" In the window that opens, select tab "Solar System" Click on "Import orbital elements in MPC format" Select the type "Comets" In the dropdown menu, select "MPC's list of observable comets" Press "Get orbital elements" In the window that opens, you'll see a list of objects. You can either select everything ("Mark All") or only those you want to add. Tick "Update existing objects" Press "Add objects", and you're done! 46P should now be visible, along with other comets you added Hope that helps! Pierre
  10. Interesting, thank you very much! Indeed, it looks quite light polluted
  11. Thanks a lot Michael for your feedback, that's a great starting point. 60s should be plenty enough, especially under my light polluted skies. Let's hope for clear skies!
  12. Hello everyone! I've never photographed a comet before, and since 46P/Wirtanen is around, I'd like to give it a try. Unfortunately, I haven't seen a clear sky for weeks now, and the weather forecasts are only predicting despair and frustration... So, since I will most likely have only one small chance to photograph 46P, between two clouds, I won't have the time to try out different setups, and I want to be prepared. Considering I'm using an APS-C camera, and imaging from a Bortle 6/7 area, what would be the optimal focal length / shutter speed? I have no idea how big and fast the comet actually is. After seeing the great pictures posted on SGL, my initial thought was that the total exposure time should be rather short, to avoid trailing after stacking. And if I'm lucky, the comet might be close to the Pleiades, so a 135mm lens around f/2.8 would make an interesting composition. Or perhaps the 200mm f/4 if the timing is good. But at these focal length, could there be visible trailing? What do you guys think? Thanks for your support! Pierre

    Trevor from AstroBackyard just published his review of the ASIair, as well as a video on his Youtube channel. That might give you an idea of how it performs! He seems very pleased with this little box. Also, there is a dedicated Facebook group operated by ZWO, where you might find additional feedback: https://www.facebook.com/groups/1105942639568958/

    Comet 46P/Wirtanen

    Thanks Davide for the explanations! I'd like to photograph 46P as well, but that's my first comet, so your explanations will be helpful Well, if the clouds that are here since weeks finally decide to annoy someone else...

    Imaging with a Fujifilm camera

    The article is finished and can be found here! Let me know if you have additional feedback or deep-sky photographs you would like to share! Thanks
