2025 Heart Nebula imagers (and multiscale mosaic?)

[ruby breach]

If you're imaging the Heart Nebula this season, clap your hands?

@clever sedge @silent skiff @slim radish @wispy spear as far as I can tell

[slim radish]

it’s a good nebula

[golden blade]

i am too with unfiltered OSC

not for long tho

[wispy spear]

I didn't bring it to a finish though...Started the middle part, got 3h on that. Then decided to do a 4 panel mosaic, got only 2h per panel

[halcyon lily]

i did in august with my 585m, 2 panel mosaic. but im redoing it now that i got my 533m

[fresh tendon]

Haven’t finished it yet

[slim radish]

the heart of the heart is so sexy man

[ruby breach]

I gotchu fam (well I'm starting to at least, this is the only data I have)

took it under a full moon so it's pretty meh (this is actually a diagnostic image)

I'm thinking, if everyone's willing to pool together some data, we could build a composite of all our images

[clever sedge]

all of y'alls suck

behold

the best heart nebula image to ever grace your eyes

[wispy spear]

I am in if anything. I can contribute 3h of a middle part and 2 hours per panel on mosaic I posted. My subs are 2min OSC via Ha-O3 filter

One of my panels is pretty much a fish head shot

[ruby breach]

We can use @clever sedge or @halcyon lily's data as the base image

@slim radish and I are covering the same region but I'm happy to dump in more time on the core (Melotte 15)

[slim radish]

the core is so sexy bruh

[wispy spear]

Ping me if my data can be of any use

[halcyon lily]

Sure

[silent skiff]

workin on it

i'll process soon... ™

shooting a 3:2:4 ratio of SHO really helped with colors

[slim radish]

i was gonna do 3:2:4 too

[ruby breach]

With your current panel we can probably combine it with @clever sedge's Fish Head closeup if he's cool with that

[celest ledge]

Random Ha session waiting for comets to rise

[ruby breach]

So what I'm thinking, for those who are interested in contributing, is building a multiscale mosaic out of your processed images. Process them however you like (probably best if you try to be distinct from those surrounding you) and then they'll all be overlaid on the base image

2025 Heart Nebula imagers (and multiscale mosaic?)

It'll be a bit chaotic, but it'll be nice to have touches of our own processing throughout the image

[ruby breach]

How much time/what instrument?

[celest ledge]

4h WO z81 imx571mm IDAS ~7nm

[ruby breach]

sounds like a METAR but I parsed all of it lmao

[silent skiff]

with some tinkering, faffing, and fiddling, i'm going to bed.

to be continued with processing at a later date, i think i can still do some tunings

[slim radish]

show my bro stars some love

but yea i should go sleep too

[silent skiff]

yea i need to work with the stars a bit more as well

but i'm exhausted from gram so that needs to wait

who knew conferences were so tiring?

[celest ledge]

Solid HSS result on IC1805.
WO z81 reduced to 450mm f/5.5
Imx571mm
IDAS SH filters
85x 300s Ha
76x 300s SII

[keen patio]

my first attempt at processing, ill try to redo with Ha and Oiii separation tn

[keen patio]

aw man i think im missing data from that part

[clever sedge]

[celest ledge]

S2

[ruby breach]

How much data for this one?

[clever sedge]

18 hours or something like that

[ruby breach]

Ohh, okay, that makes a lot of sense. I was worried that I had badly misprocessed my data with 2 hours of H-alpha (on a full moon to boot)

But that's just nowhere near enough it seems

[ruby breach]

Current state (HOO, 2 hours per panel per channel). Debating whether to get S-II, H-alpha, or O-III tonight

[carmine mural]

stitching issues?

ad hoc mosaics are actually so underrated

[ruby breach]

Yeah I'm inspired to go for it myself

[carmine mural]

why make square when polygon

[ruby breach]

Especially when you save as a PNG and make the background transparent

[celest ledge]

no issues, just 3 separate images from different kits, and times that happen to have some overlap.

[carmine mural]

oh yeah ofc, but there is a weird dark area right in the center

looks unnatural

[ruby breach]

Am I spotting the Maffei galaxies in there

[carmine mural]

and trust me i've been looking at stitching issues for WEEKS 😭

FINALLY got it perfect today tho

[ruby breach]

Small oof

[celest ledge]

🤷 oh well, not intended to be a masterpiece. one pannel is maybe an hr, one was actually osc converted to grey scale. im not to concerned with something looking 'weird' to someone.

[carmine mural]

ah, i see

not meant for a clean image, just a curiosity

crazy how there's not issues with SNR differences?

[celest ledge]

I wasnt really aware of abell 6 and hfg1 and the relationship in position to ic805, so i stitched those 2 together, but then i had lots of blank space, so i looked for something else I had to help fill some gaps

thats where the soul came in

and i thought it was kind of interesting

[ruby breach]

@celest ledge would you be interested in contributing your data to the multiscale mosaic project I'm trying to work on?

[carmine mural]

what are we mosaicing?

[celest ledge]

yeah sounds neat

[ruby breach]

All of the Heart Nebula images people are sharing here, should they want to contribute. A giant patchwork

Representing everyone's different processing styles and FOVs

[carmine mural]

ohhhh, so not a regular mosaic, just a wall of hearts?

[ruby breach]

I was thinking of astrometrically aligning all of our data and layering it together into a chaotic quilt, but this would also be cool

[carmine mural]

that's sounds insane lmfao

i'm in

[ruby breach]

You got any Heart data?

[carmine mural]

30 hrs

[ruby breach]

Hell yeah

[carmine mural]

i'll show it when starx finishes on the cygnus mosaic lol

[ruby breach]

I'll create a place for people to dump their platesolved FITS files (after processing) and I'll figure out the registration and layering

[carmine mural]

grrrrrrrrrrr

i hate this

it looked so good before star removal

[celest ledge]

like maybe take a base heart image, and divide it into number of sections as there are contributors, and assign each segment to a contributor, then have each contributor submit their platesovled section?

then stich all the segmetns together

[carmine mural]

why is it not possible to use photometric mosaic with a synthetic star field or something :(

[ruby breach]

It may need to be broken down into segments because a) many people may image at similar scales and I'd like to ensure they're all represented, and b) some of us are imaging at very small scales and it would be better to process those segments from a small scale up

Like I'm focusing on the core, and I may layer my portion onto nexy's, then layer nexy's onto someone else's

[celest ledge]

oic

[ruby breach]

But I will align everything astrometrically at the end of the day

[celest ledge]

most of my data in this region is pretty wide, 130, 270, 450. not too much that focus on mellot 15

[carmine mural]

here it is

[ruby breach]

Here's the place to upload the files: https://1drv.ms/f/c/4f69734a5f0092dc/EiTmMWflsQhHkI9JviC5HnsBfgXhKGjnFrpya8I74KK7yA?e=pjmb0T
Include a platesolved FITS (strongly preferred) or XISF file of your final process that you'd like to contribute to the mosaic, and be sure the filename includes your Discord name so I know who contributed what portion.
Tagging @carmine mural @celest ledge @wispy spear @halcyon lily, and it's open to anyone who wants to contribute.

Let me know if you run into any issues with uploading

Actually @civic marsh (congratulations, you are the chosen one) do you mind pinning the message with the upload link in this thread?

[carmine mural]

do you take xisf?

i can't for the life of me get pix to save the platesolve to a fits for some reason

[ruby breach]

Sure (edited post to mention that). As long as I can open it in SIRIL and keep the platesolve data it's all good

[ruby breach]

Chromaticity map of the core (O - H)

[wispy spear]

@ruby breach Added my file. It's my first and only mosaic attempt so far, so if its not up to the quality to be included in the project, I'll understand 🙂

[ruby breach]

Thanks! My goal is to try to incorporate everyone who is interested in participating

I might have to split your panels to do so, and if that's the case I may ask you to send me just one panel

[wispy spear]

this is how jpg looks

[ruby breach]

Because so many people have images of the full nebula I'll likely have to chop them up as part of the assembly

[wispy spear]

I also have this section separately, let me know if it can be of use

[celest ledge]

I think this would actually be really cool. A true patchwork image

[ruby breach]

And a great tribute to everyone in the community

[ruby breach]

Feel free to upload it - not sure which regions I'll incorporate yet

[celest ledge]

It'll be a neat project

[wispy spear]

done

[halcyon lily]

i can't upload it to the drive cause my microsoft account storage is full lol. ill put it here if someone wants to put it in

[ruby breach]

Got it, thanks

[ruby breach]

Also want to loop in @slim radish @clever sedge @silent skiff in case you want to join in

[ruby breach]

Looks like XISF plate solve solutions don't carry over to SIRIL...I'll have to figure out another way of doing this

I might write an XISF library just to solve this issue, but in the meantime I will encourage FITS format submissions

[carmine mural]

From what I found, Pix platesolves are incompatible with FITS, so if you use pix you can't save it unless you use XISF

[ruby breach]

Me when I'm in a "who can take more L's" contest and my opponent is PixInsight

That's actually embarrassing

W**t the actual hell

[carmine mural]

Yup

Hella cringe

[slim radish]

i only have Ha data

i’ll get some o3 and s2 too

[celest ledge]

I was thinking about imaging tonight but the humidity is super high. I took a couple frames and then decided I wasnt gonna deal with soggy kit so I packed it up. Here are my 2 frames of 10m in S2 on Mellot 15 stacked that i got for my troubles.

[clever sedge]

I just added my RedCat Heart data
