First guiding - CORRECT PICTURE :)

[LewisM]

Decided on 2 minute subs x 20 at ISO 800. Camera was having heat fits - one point it hit 50°, whereby I went and got a pedestal fan and blasted it (down to 28°). Still suburban light pollution, sigh. Focus a LITTLE soft.

Finishing the peltier box today!

Getting there. Not much colour or contrast as yet, nor depth. Keep on keepin' on!

OOPS! WRONG FILE! Change that in a sec

Nice one Lewis,

Are you processing in DSS with JPEGs or RAW files?

It seems a little washed out for 40 mins, I suspect JPEG?

Nice start though

cheers

[LewisM]

It's the wrong file Chris :))

EDIT: NOW the right picture

[Screwdriverone]

Ahh,

As you were then, I shall wait for the update.

BTW, DSS washes out too much, so FINALLY got MaxIM DL working right. It rejected only 6 images, so that's a 28 minute stack.

Got to work on focus more. LOOKED right - obviously not quite

[LewisM]

Though, I like this one better after resetting a few parameters in MaxIM DL...

More natural IMHO. This is WITHOUT bias or darks, as I cannot understand WHY MaxIM won't use my files for this - rejects all my darks, flats and bias...

[Screwdriverone]

now thats better.

You are right about the focus, the stars are a bit bloated over the diffraction spikes.

Get yourself a bahtinov mask, worth their weight in gold for focus.

I set my camera into Backyard EOS frame&focus and then press the 5x button when looking at a brightish star, focused in less than 30 secs, mask comes off, snap away.

Keep em coming, thats a great result so far.

Cheers

I do have a Bahtinov... looked right... obviously not quite, and that was using APT's focus meter.Ah well, better luck MAYBE tonight.

Still, happy with the end result considering no flat, bias or dark subtraction. Canon's internal magic seems to work well for the most part on these full-frame cameras.

Nice shot Lewis, you can really see some detail and structure.
