Antares with Polarie, 60Da and 50mm lens

[IanP]

This image is the product of 2h (2x60x1min @ ISO2500) of exposure captured in two sessions using POLARIE.
Here in Perth the geographic and magnetic south differ only by approximately 1deg, so setting up the POLARIE is a piece of cake: a little bit more than 30deg (31.5) as the angle of elevation and almost in line south with a compass.
Processed in PixInsight with MBias and MDark applied.

Always a beautiful perspective. The Antares Rho complex is something of a jewel studded pendant, strung on long threads of dust. Very nice.

That really is a good image Ian!:thumbsup:

Nice and sharp, subtle colour.

Cheers,

Justin.

Nice image Ian - it's becoming one of my favorite subjects too.
Was that taken in Perth? Or did you get out a bit?
Cheers,
Andrew.

[IanP]

Thanks Andrew,
The images were taken in Perth (Churchlands).

Great looking photo Ian.

One of the most beautiful parts of the sky and you have photographed it perfectly..what a great composition!

The Canon 60Da, at 2500 ISO, has captured amazing colour and details.

Missed that one. Superb field. :thumbsup:

[Elio]

Nice image, I love widest field :thumbsup:

At 50mm no need a great precision, here you can find mine version, using a poor eq3 with sideral rate, subs are about 300s :)

The framing in your version is almost the same as in mine, just the colour balances are touch different, but that is always a matter of personal preferences.

Neat what can be done with these little tracking mounts and modern DSLR's :) Nice example :)

hi ian..... love the pic firstly!
what lens did you use and aperture? on Antares you can see the
blades(?) of the iris, is that right and is that what it is?
I have a 60da and a Samyang 35mm plus a good LP filter and don't seem to be able to extract much exposure before the sensor becomes polluted
I am in mount hawthorn so our skies are really the same
did you use an LP filter too?

Hi Pat,
From Churchlands, I never take shots in CBD direction è eastlish. Most of my shots have been taken right up, looking slightly south-west.
In this instance I used 50mm, F1.4, slowed to 5.6.
This particular lens produces that “nice” shape of brighter stars with blades.
I have Astronomik CLS clip filter but I don’t use it.
In my opinion, and some users don’t share it, these filters irreversibly spoil the colour balance and also remove “something” from the data.
:hi:

[blink138]

food for thought there ian........ i thought an LP filter would be an absolute necessity!
i very much like your result and i must give it a crack as i have the 60da and a 35mm samyang f1.4 and we are a similar distance from the cbd

[redomatic]

Yes, Great work and you have inspired me to try and get Andromeda again with the Polarie!!

[Ross G]

Congratulations on IOTW Ian.

A beautiful photo....well deserved.


Ross.

[gregbradley]

Great image. You got an ideal focal length there to fit it all in and enough signal to get the blue horsehead as well. Nice.

Greg.

[Camknox]

Awesome photo, congratulations!

Well done...and congrats for IOTW :thumbsup:

[IanP]

Thanks David, Jase …
:thanx:


In a message to me Paul Haese pointed out that the image had to much green tone, so following his advice I produced newer version of the original image by going through PixInsight SCNR-Green-0.2 .. :hi:

Thanks Paul ..
:thanx:

Now Ian, that's an image to be proud of, I like the new version much better.
And Good on you Paul for helping Ian out.

:thumbsup:

[jase]

Yes, good call on the green made by Paul. The changes have made the colours more distinct. They really pop now. Top work!

[iceman]

Replaced the IOTW with the new version :)

[gregbradley]

Yes that looks even better. I often find my astro images have a bit too much green in them. Yet I often image at my dark site which is nearly completely dark and almost no light pollution.

After doing a lot of widefield DSLR imaging I could see the sky is often green with skyglow. I presume that is where the extra unwanted green comes from. It isn't every night either so that factor also throws you.

Greg.

[Rod771]

Yep! That's the one, well done Ian

Go SCNR! :)
