m51 in JPG :S !!

[AstroLuke]

I was out last night and made almost two hours worth of subs on m51, but when i woke up this morning i got to think about whether i set the image settings to raw....

Well i didnt, its jpg. Is it possible to get something out of jpg or is it a lost cause?

I am sure you will get something out of it, you can stack JPEG in DSS, so you should get something. I think you will just be limited in what you will get out of an image when you come to mess about with it isn PS.

Sure. Stack it and see what happens.

JPEGs will limit the amount of fine detail that can be extracted when stretching, so if it was a target with lots of faint nebulosity then you would lose some data.

I used to take all my images in JPG, till I realised there was a better way.

So yes you'll get something, and hopefully you'll be happy with it.

Been there, done that a coupple of times - and afterwards, i've never used the JPG settings ever again unless i was shooting a timelapse at the smallest JPG...

But yes, you will still get details out of it, but it will be limited to less details then from a raw. Especially if it's underexposed. If it's well exposed i've got OK-ish results from JPG as well.

You might need flats/darks etc in jpg as well. I discovered that on my 1000D RAWs are a slightly different size from jpegs, so DSS wouldn't mix the two. So when I made this mistake recently, I did a special run of jpeg flats (at roughly the same camera angle - I didn't discover the problem until I had taken the camera off the scope).

I've got that T-Shirt, too. Thankfully, I don't have to remember any more now I use APT. Also, I always leave it in RAW+jpeg mode for daytime photography, just in case...

Its good practice for learning to always check your in raw mode not jpeg, but you should be able to get something from it. I did that with a few galaxy's in the past and still got a reasonable result but most frustrating to find there in jpeg and not raw.
