WR 134

My first shot with a dedicated astro-cam (ZWO 2600MC Pro)

I'd really like to add some more narrowband data to this as well as some broadband for star colors. I need to wait until neared a new moon for the boradband data. Overall a work in process but Ithaca, NY is notoriously cloudy :(

Three nights of a 95%+ full moon

81×300s exposures using Ha+OIII 3nm dualband filter

74x300s exposures using OIII+SII 7nm dualband filter

Elephant's Trunk

The last image I will ever take with my stock Canon 5D Mark IV. Just got a ZWO 2600 MC Pro and two filters.

OSC with narrowband filters processing question

Heyo! I'm looking for the best way to do a certain kind of processing. I have three data sets on one target: one taken with a dual narrowband 3nm Ha and OIII, one taken with dual narrowband 7nm OIII and SII, and one set of unfiltered broadband data. All taken on a ZWO 2600MC Pro.

What I really want is the subteltly of color from my broadband data, and the luminance and detail from my narroband data. I imagine I could just use the narrowband data as a luminance channel and the broadband as RGB but then I sacrifice the "clean" look of the narrowband don't I? Is there a superior way of masking the nebulosity so that the background stays clean without being "degraded" by the broadband data, while still retaining broadband colors? Maybe some photoshop layers/channels magic?

I really want the best of both worlds. I find SHO images to lack a little subteltly in color gradation that I see from broadband OSC images, while those broadband OSC images are missing some contrast and detail

I am very new to this so the answer may be very obvious, or the question might be inherently flawed.

"It's not that deep"

90% of the time these days this is just used as an anti-intellectual way of passively dismissing a voiced concern that the listener (or reader) isn't willing to, or capable of considering/engaging with. I think it makes the person who says it feel like they made a point when (to me) it just reads as "I don't even understand what you said and I don't actually care enough about understanding the world or using my brain to try". Of course I expect the now required "it's not that deep" responses to this post. Fair play.

Found phone in Stewart Park. Second post (original post won't let me post a photo in comments) Do you recognize this person?

Phone found at Stewart Park. If you can tell me what your background is, or the hilarious name of the alarm that went off at 3pm, it's yours

Narrowband (dual or quad) filters worth using in bortle 4 area? Detailed question below

I just upgraded from a stock Canon 5D Mark IV to a 2600mc. Honestly apart from the no cooling, canon banding issues, and a mirror shadow across the bottom of every image; I was loving the shots I was able to get with my 5D Mark IV. They seemed to have colors I liked a lot more than many I see on astrobin.

My 2600 arrives tomorrow and I'm wondering if I should bother trying a filter. I loved the rich variety of colors I was getting with no filter on my old camera and I worry that even a quad band will produce images with less subtle color gradients and richness. If it ain't broke don't fix it? Cheers

NGC 7000

Work in progress. Just a reminder you can still shoot under a full moon despite what some will tell you. Shooting more on this tonight and will re-proccess with the added data.

About 3-4 hours of data, 98% moon, bortle 4 area.

Best alternative to netafim? I don't want to continue supporting an Isreali company

I was using their whips, ring emitters, arkal filters...everything. Sending money directly to Isreal doesn't sit with me. They get it out of my taxes as it is.

PSA: Pirates of The Caribbean (at least the first one) is the wrong aspect ratio on prime video. Do not rent. Everyone is stretched vertically. It is correct on Disney+

I spilled about a pint of old gasoline right above my well. Is this probably fine? It wasn't intentional. I know gas has some pretty bad stuff in it.

What are the best nebulae to photograph from NY state right now (42°N)? Looks like the North American Nebula should get high enough tonight...I know were are juuuuuust exiting galaxy season and I am not very experienced. My 509mm focal length on a full frame sensor isn't so conducive to galaxies.

Appreciation post for Station Eleven

I just feel like this show was so criminally under-watched. Everyone has their taste, but for me this ten episode HBO series based on the novel of the same name by Emily St. John Mandel is a masterpiece. The pacing, the acting, the humanity...it's just near-perfect television. I have seen 100x the posts about (for example) The Last of Us, when (to me) Station Eleven is superior in just about every way. Not that any direct comparison is sensible or possible. Watch this show if you haven't. You will be so pleasantly surprised
