[@human_1248]

@@anuranjan0101 yes but it also affects the way some animals navigate (they use stars) and it also effects people’s sleep. Also I’m not saying to remove all lights, that would just be dangerous. The problem is most artificial lights aren’t even necessary

This is excellent. I always wanted to see an astrophotographer do this on KZbin--compare image quality at differing Bortle levels only. Thanks so much for this!

[@DavidStrong-yy4th]

Hi Trevor, another great video! It was nice meeting you down at the Winter Star Party. I think you've got everyone thinking about a trip to a dark sky site. It can be a blast or a disaster. A video on planning and preparing for such a trip would be very helpful.

[@Itashroxastronomical]

The photo in your name is my profile picture 😂

[@Si-fp2ij]

Great comparison Trevor! Drove 2hrs to my first Bortle 1 site at Christmas and was blown away with the difference both visually and with the images taken. Cheers Simon

[@josh8560]

Thank you for making this video. Until now i never saw a video that compared light pollution vs dark sky so easily!

[@Bodhiscott22]

I live in the suberbs of hawaii in bortle class 4. At about 3am when all the neighbors lights go out the milky way litarely looks like a whitish glow and even some darker details. since I have started astro photography I have appreciated the sky much more.

[@zalllon]

You are lucky! Good weather and access to darker skies from your home (I live in Toronto area, so Bortle 8-9). When I was on my honeymoon in 2018, the last place we stayed was on the Big Island and I was blown away looking up at the night sky, seeing colours. I took one pic with my Fujifilm XT2 camera and an F4 lens and have always been blown away from what I captured in one shot (I wasn’t into astrophotography till about 4 months ago). Can’t wait to get access to even darker skies again now that I have an interest in this hobby.

[@SpaceIsBeautiful]

I really wish that our governments would have something like a designated dark sky night where all city lights are shut off for the span of a few hours or so just to give astrophotographers and astronomers can be under some dark skies for a while

[@MountainFisher]

Did you hear about Los Angeles when the electricity went out? (11 was swamped with calls from people freaking out about the sky. Didn't know it was the Milky Way.

[@Sharpless2]

@@MountainFisher Really showed the level of education at that time. Astronomy should be taught in school from grade 1. This way more people would care, would show more interest in the most precious thing we have, and could work against light pollution together.

[@aman_s_96]

​@@Sharpless2Basic astronomy is taught, still people don't want to learn.

[@paulglennie1991]

You know it would just end up being cloudy lol

[@scorpianspirit5124]

I am extremely fortunate as I live south of Moab Utah in a bortal 2 sky. Moab has been diligently working on their dark sky certification and we do have three dark sky locations that are listed as such. Arches National Park, Dead Horse point, and Canyon Lands National park are all within a thirty to forty minute drive. I am excited to see our small community take dark skies seriously. I have only recently got back into astro imaging after taking about ten years off. My how the tech has changed ! That is one of the reasons I have taken the hobby up again. Compared to where it was ten years ago, it almost feels like cheating with products like the ASIair and the like..... Great video, thumbs up... Cheers !

[@adamfieldhouse311]

Where I live I am so lucky. I live in rural Ireland and sit on the boundary between Bortle 3 and 4 skies. The milky way is really clear above head with the naked eye. Dak skies are more important than expensive optics in my opinion. Keep up the good work.

[@LittleHubble]

Awesome video!!

[@cristianmoore1996]

I live in a Bortle 5 and I’m going to a Bortle 2 state park next month. I’m excited!

I’ve been an astrophotographer for about 4 years, your videos are always a great help. Much appreciation! I moved to my off grid property 2 years ago on a small island in northern Michigan. We have Bortle 1 skies all year round, very lucky to be here. It’s right on the Canadian border, come with your travel kit!!

[@Trottinet-work]

Love your message! The first time I saw the night sky ,the Milky Way, I was nailed to the ground beyond belief. Seeing the firmament at night was the most beautiful thing I ever experienced.

[@derrymurphy3944]

Excellent video I count myself lucky that I live in bortle 4 class skies I notice such a difference when I visit family who live in the city so much less to be seen when I look up where I live I can see Orion and the Pleiades with the naked eye

[@jamesbonser9667]

Thanks for doing this, Trever. I live in a Bortle 4 area in Iowa and I love the beautiful views of the Milky Way from my backyard and your video makes me appreciate my dark skies even more. I could wish for more clear nights to take advantage of the dark skies but life is full of challenges, eh? and honestly, overcoming the challenges make the results sweeter. Clear Skies!

[@LearnToStargaze]

Bortle 8 in our backyard in Halifax, 3 or 4 at our stargazing park (Stargaze Nova Scotia) 30 minutes away near Peggy’s Cove. I really need to measure the sky brightness at Stargaze NS to get an objective measurement. The biggest advantage I’ve seen is no gradients from dark skies.

[@briankotak403]

Yes. I cherish my rural, bortle 2 sky at home and at the cottage and am just awe-struck at the bortle 1 sky I have up at a remote lodge in northern Manitoba where I work in the autumn. Makes a huge difference! However, I’m jealous of your lack of snow in the video! Lots of snow here in southeast Manitoba. Was -20oC this morning too. Looking forward to spring. Dr B from Manitoba, Canada 🇨🇦

[@fredaw61]

I live as well at the edge of a town and the Bortle map list me at a 6 however the resent addition of a apartment complex just finished up about 5 months ago and their lights are huge and bright. I noticed in you time lapse how many stars were around Orion. I can basically see the main constellation itself and no longer see the smaller stars. I almost wonder if my house is in a Bortle 7 to 8 now. I do visual so I may be selling everything I bought last year. I kind of regret getting back into Astronomy just because of the light pollution here and getting to dark sky’s is over 1 1/2 hours away.

[@AstroForumSpace]

Still the most engaging AP channel, awesome! It's not only LP but also atmospheric turbulence with the horsehead low above the horizon at 50+ latitude. Let's shoot some galaxies 🎉

[@zalllon]

I only have a Seestar S50 (had it for about 3 months now), and have seen a big difference. While I’ve been amazed by what I could get from backyard / driveway in a Bortle 8-9 (Brampton, ON) … a darker sky at Bortle 4 (about an hour drive north west of me), I was blown away from what I captured from 3 nights ago in that darker sky. I went from thinking “this little unit is cool, nice to able to do capture stuff” to “OMG, this thing is amazing … I need to have a plan to get out here every clear night I can”. For context I have 5 hours from several nights at home of the Orion Nebula from my driveway, and compared it to just the other night’s 2 hrs and 40 mins from a Bortle 4. Mind boggling improvement (I used mosaic feature on the seestar for the dark sky, which really means each panel exposure has 9 times less exposure of light).

[@PlanetaryDefenseFoundation]

My favorite astrophotography channel.

[@wwrp155]

My back garden is Bortle 4 and even luckier, I live 30 minutes away from Bortle 2 skies. I feel very blessed to be positioned where I am.

[@ronrotunno2901]

I drove through northeastern New Mexico yesterday which was Bortle 2, I was very excited about the proposition of such a sky but it was during the day. I would have loved to stop and spend the night there but we’re relocating from the Midwest to Arizona and we had bigger fish to fry (namely getting to our final destination). Hopefully I’ll find something similar once we hit AZ. We’ll be situated at the last subdivision before a mountain range…time will tell. Excellent video Trevor. Thank you.

[@robb7342]

Nice comparison Trevor and why I head up the road to B2 when shooting the milkyway with the SLR. I was shooting OSC with Antlia DB filter and was shocked at how much impact the full moon had as well.

[@callumsastrophotography4859]

Hi Trevor, Bortle 7 here and just use a UV IR cut filter for broadband targets. Try to maximise shooting when Moon is not up and collect lots of subs. Works well but I know it would take a fraction of the time if the sky was darker. Most people are so cut off from the night sky in a city they don’t care if they make the problem worse. Keep up the good work!

[@MountainFisher]

My son's house is Bortle 4 at 5200 feet, 20 mins. Bortle 2 near White Sands Missile Range, 30 mins. Bortle one 90 mins and northern border of WSMR, watch out for cows called bulls.

[@flint2kuk]

Thank you Trevor! I’m in a bortle 5 area, and have only attempted Andromeda without any narrow band filters. I’m definitely going to try other targets after watching this video.

[@gptravel531]

We snowbird at a Bortle 2/3 area in north western Florida; live in a Bortle 8 in SW Ohio. The difference is absolutely unbelievable! Great comparison!

[@collintatusko4155]

I have very fond memories of a sky full of the Milky Way and stars upon stars growing up in the Upstate NY area. Over the past few years have returned home for the final times and over 35+ years, you see maybe 1/4 of what was once present in the night sky. Nothing surpasses the personal calm and peace while sitting under a canvas of stars. I live in Washington DC now…and remember fondly my childhood days laying in the grass watching satellites pass until my parents yelled it was time to come inside.

Hi Trevor ! still great video as always. You are really lucky with both Bortle 6 and 3. I live in Hanoi, the capital city of Vietnam. On February 12, 2024, according to the Lunar Calendar, it is Tet Holiday. I went outside and saw Betelgeuse and Rigel, I knew it was the constellation Orion. I quickly ran into the house, took out my tripod and Iphone XS Max and started taking photos. The result I got was that the sky in Hanoi was very bright (Bortle 7), the star Orion appeared faint, but still a wonderful experience for me. I just wish that in Vietnam, people understand more about light pollution and hope that Vietnam has an IDSP Best wishes to Trevor and all of you from Vietnam 🇻🇳🇻🇳🇻🇳.

To get anywhere near close, even then its not equal. I'd say multiply your exposure by 3 or better for doubling the Bortle.

Hello, I bought the Apertura AD8 Dobsonian 8" telescope that you recommended in your beginner telescope video. I also recently bought a DSLR camera as well. I tried buying one of the connectors to put my DSLR through the eyepiece, but when I did, it would not focus, I would adjust the focus knob all the way in both directions, but it wouldn’t focus enough to see anything. I was contacting you to see if you can send me the name and possibly a link to the one you use to connect your DSLR to your Dobsonian. The camera is a Cannon Rebel T7 if that means anything. Thanks

[@TheMatrix365]

Love your videos and have helped me get a better understanding of things. I am going out to Utah in a few weeks and was thinking about getting an ASIAir or a model similar to use with my Canon 90D and my Star Adventure GTI that I just received. Do I gain anything by getting the ASIAir type device with my DSLR and do I need a Guide Scope to get the most out of things or is the GTI going to be good enough. This will be my first go at Deep Space so just trying to see what would work best for my DSLR and 135mm Lens.

I have to drive like 2 hours to get to the nearest "dark sky preserve" and every time I've gone it's never been as good as some nights in my home town which is also 2 hours away even though all the dark sky maps show it should be worse in my home town.

[@PilotPhteven]

"no filter".. ok.. yes.. fair.. but how much is the difference with filters. Especially HSO filters.. I moved from a Bortle 4 to a Bortle 7.. I do miss it a little.. I can drive out to a Bortle 3 in about 2 hours, have yet to do that though.

I shot the Horsehead and Flame the last week of February with a Canon R7 and 200mm f/4.0 lens. Bortel Class 8, (Omaha, NW) ISO 800, 13 secs, 9.24 hour exposure total. Best I've ever gotten of it but sure doesn't compare with yours!

[@SciMajor1]

I'd love to see the difference if you keep all the parameters the same but use a good light pollution filter for your shot. How much would the light pollution filter close the gap between the two skies?
