First try with wide field.

This is a stack of 12 * 30 seconds iso800 F5.6 at 200mm.
Processed in Registax 4 and further processed in cs3.
Star trailing is present because the tripod wasn't setup properly :whistle:
No guiding.
Camera Minolta dimage 7i


Can anyone tell me what these are? (could not find it in The Sky).
South next to crux.

Nice shot Mill! :thumbsup: :thumbsup: The neb is NGC3372 Eta Carinae nebula, while NGC3532 is the open star cluster top-centre. There is no Crux!?

As Rob say, sorry ol' bean but you have missed Crux by about 6 degrees.

At 200mm FL then you would only be able to expose for 5 sec and not get trailing.

t = 1000/FL (near the pole) and t = 700/FL ( near the celestial equator)

Was that with a standard camera tripod or with an equatorial mount?

[mill]

It was with an equatorial mount Paul, but not properly polar aligned.
Still have to master that.

I have marked them for you Martin :thumbsup:

[mill]

Thank you Ken :thumbsup:
When i come over to snake valley in November i hope to have the polar aligment right and be ready to make some better pics :D

[ballaratdragons]

We'll all have a fiddle and have you pointing North in no time!

or is that west :confuse3:

[jjjnettie]

Hey, you've done well for your first go!!
What's your next target?

[mill]

Hi jeanette my next target will be ..............Eta Carinae nebula:whistle:
Easy to do and practice on.
Joking aside, i first want to get one thing just about perfect and only then move to the next.

[mill]

Been out again and did some better polar alignment.

[jjjnettie]

That fixed up that bit of trailing. Good o.

[Tamtarn]

That's quite an improvement on you polar alignment Mill, you can certainly see the difference

Well done :thumbsup:

[Octane]

mill,

Nicely done. As with a couple of other images posted in the forum, I opened them in Photoshop, removed the redundant (overlapping) images and tried processing them. There's usually a lot more data hidden in the images than you would think.

The second image is a vast improvement on the first.

You got one of my favourite clusters!

Well done.

Humayun

[mill]

Thank you everyone. :)
And especially Humayun, Very kind words from the master of imaging (now i will have to do better and better).

Reprocessed in photoshop.
Comments welcome.
Did curves, smoothing and noise/color noise supression.
