ASI533MC or ASI294MC

[tame whale]

hesitating on which cam I should get and if the 294MC is worth the 300 bucks difference

[signal gulch]

294MC has a slightly wider FOV i believe, However the 533 is a better sensor and I would say don't get the 294

[indigo thistle]

Isnt the 294 the one everyone seems to have problems with?

[tall lark]

It has tricky flats but it's not as bad as people say

I would still get the most recent sensor tho

[fervent cliff]

iirc the 294 has amp glow, the 533 does not. That alone is reason enough for me to go for a 533 (I literally bought one today).
Clean lights will always be better than lights that need calibration frames to look good.

[tropic relic]

Personally the 533 it has such incredibly clean data, its unbelieveable, these was taken by @sonic marsh with a 533mc pro and EdgeHD 8

The sensor is unbelievably good especially for the price too

[indigo thistle]

Incredible images

[tropic relic]

They are indeed!

[fervent valve]

dither

dithering removes most of the noise

a,p glow i mean

[indigo thistle]

No it doesnt lol

[tall lark]

The parts that would be covered by the glow move a but with dithering so in theory it should be able to fill the missing pieces

Not sure how well it works

[indigo thistle]

There is no way dithering can remove this

[tall lark]

Oh wow that's bad, is that the 294?

[indigo thistle]

Apparently

Found it on stagazers lounge

[tall lark]

Yeah that rules out the 294 for me

[fervent valve]

ho wlong is that dark

tf is up with that cam

thi sis my 5 minutes master dark

no dakrs

@indigo thistle have you dithered with a 294 before?

[indigo thistle]

I didn't. Cant afford it . But there is still some amp glow visible in your image. And the more you strech the more it will be visible

Make it starless and strech more. I am very much certain that dithering cannot fix amp glow

Darks help a lot but its still better to just not have it....

[signal gulch]

yeah i can see the amp glow

[fervent cliff]

More like rotate your camera 180 degrees. You'd need to do some extreme dithering to solve amp glow. But then again, clean lights are always better than lights that need calibration frames to look good. But that's just my 2 cents

[flat cargo]

Ignore that its overexposed, where is the ampglow? @indigo thistle

You all are overreacting, the 533 aint better, it just has no ampglow, in general its the cam with bigger pixels and a smaller sensor so ye

Only good because its cheap

Or better said it would be better only because its cheaper

[indigo thistle]

No dark frames?

[flat cargo]

Yes, no darks

Oh no

No bias

With darks

[indigo thistle]

Well yeah. That makes sense. Darks fix it

[flat cargo]

Its totally fine

Most people having problems with it fail at taking good calibration frames

And that kicks back on its image

[indigo thistle]

Yeah. I have heard flats are not easy to capture with 294

At least good ones are

[flat cargo]

They are, i take them at .8 with a tshirt and my laptop 😂 idk what everyone has, mine work all the time

[indigo thistle]

Weird stuff. The thing i was talking about before was that you cant remove amp glow with dithering. Not that ampglow is the worse thing that happened to the world after 9/11 (obvious exaggerating:) )

[flat cargo]

Ye, dithering helps to get data on the overshadowed parts

[tropic relic]

I mean, personally id rather have smaller pixels anyway, calibration frames with the 294 ive heard arent a easy game normally, but generally the 533 sensor is newer, and having smaller pixels is nice, would rather not have to drizzle, and if using high focal length would rather be oversampled or binning

Thats just my opinion though, the 294 is still a great cam regardless

[flat cargo]

I honestly dont know why everyone has problems with calibration frames

They are soooo easy i could cry

The owner of my cam had problems too

Its not the cam

[tropic relic]

Tbf i can understand not being good at calibration frames XD i suck at flats, but yeah its down to the person, if they dont mind bigger pixels and amp glow but have a bigger sensor then sure, but if sensor size has nothing to do with it, and they are using shorter focal lengths, the 533 has it imo

[flat cargo]

(The person owning the cam before me)

[tropic relic]

Yeah lol

[flat cargo]

Ye with shorter focal lenghts id take the 533 too probably

[signal gulch]

Amp glow can be calibrated but that doesn't mean the 294 is better

[tropic relic]

Your not wrong, both cams have ups and downs, like the 533 sensor is small for my liking, but the 294 has big pixels

[flat cargo]

Ye its really up to personal liking tbf

@tropic relic 😂

[tropic relic]

Bruh the fact that got failed to send XD

[flat cargo]

Ye xd

[tropic relic]

But yeah thats pretty funny cant lie XD, over time surely itd get easier to take them

[flat cargo]

Like i had never really problems with them

I take them cooled all the time,

Darks (like darks lol)
Darkflats 0.8s
Flats 0.8s

(Flats with a tshirt + rubberband, laptop = about 75% brightness, white image i screenshotted somewhere, i take them too cooled)

[indigo thistle]

Could it be that there are some quality control issues or something?

My friend used to have 294 and his biggest problem was that calibration worked 75% of the time. But on some nights it just wouldn't. And he got fed up

[tropic relic]

Darks and bias frames are really easy lol, flats ive always had issues with, atleast with the C8 (not so much with the quattro) but they used to cause walking noise, wouldnt actually correct properly, or would make the actual images noise sooo much worse to a point id rather deal without them. After getting a UV/IR cut filter it somehow fixed most of my issues? still weird cant lie lol

My flats length needs to be 1-10 seconds otherwise it makes the end image incredibly noisy

[flat cargo]

Its a user error like 100% if they work one time they work all the time

[flat cargo]

Try without bias

I too take no bias frames

[tropic relic]

Even worse

Dark flats same result

[flat cargo]

Show me your issue

[tropic relic]

Was it darks and bias? or just flats? flats can always be inconsistent tbf

[tropic relic]

I got some old pics of it, 2 seconds

[indigo thistle]

I remember him getting some goofy gradients from flats

[tropic relic]

@flat cargo cant find the direct comparisons that i took, think i deleted them, but heres M106, this image didnt get the walking noise or bad noise because i took long flats, (4 seconds) but you can see where it "Tried" to correct the dust spots, the top right is where my OAG slightly sits in frame, and didnt

[flat cargo]

You know whats weird

[tropic relic]

Yeah, i hate flats XD

[flat cargo]

I had kinda the same vignetting going on with my old 150pds but it was gone when i used my apo, think it was a light leak of some sort

[tropic relic]

Strange, its really weird though, when i didnt shoot flats, it wasnt there, its like it tried to correct the wrong corner where the OAG is, your would make sense for a light leak yeah

I got alot of examples of the same things happening

[flat cargo]

If you have a chance try it with a apo one time, with the settings i shared, i swear you will succeed

[tropic relic]

Yeah, its weird, the quattros flat work 100% of the time, the C8s dont though

[glossy pecan]

I use the ASI294MC and to be honest I haven't had any issues with it. The amp glow is kinda faint and can be easily taken care of with dark frames.

This pic is kinda out of focus cause a stray cat was bumping the tripod aggressively. but overall there was little to no amp glow when I took this pic

[dusky shore]

no . L + Ratio + 294 sucks
