My Favorites

Posted By Greg Bradley
I have been reorganising my images from the last several years and have made a collection of the images I have taken I like the best.

Out of over 100 images I got about 14.

Perhaps part of imaging is to take lots of images as some just don't catch your
fancy at the end of the process and others fall in your lap.

NGC6744

Posted By Greg Bradley
This one is a reprocess of an earlier image I was never happy with.

A beautiful southern galaxy and perhaps the queen of them all.

7 hours, RCOS12.5inch, STL11000M, Astrodon filters, Tak NJP mount.

Taken at my dark site in NSW Australia.

NGC6188

Posted By Greg Bradley
The weather pattern in SE Australia has not been very favorable for imaging for some time. My last
3 trips to my dark site (a 3.5 hour trip each way) has lead to only 1 clear night out of 11.

Anyway enough of the moaning - here is NGC6188 using a TEC180mm FL and Apogee U16M camera, Apogee filterwheel, Baader filters and Tak NJP mount (a bit small for the large TEC scope).

5 Hours and 30 minutes HaLRGB 120 30 60 60 60, good seeing, no wind, totally clear (yah!) and no light pollution, cold (at least for Australia 3C).

Omega Centauri

Posted By Greg Bradley
This was a difficult image as I had made several trips to my dark site only to be
disappointed with clouds/rain. There would be a brief opening in the weather
only to be stopped before I could get a complete LRGB.

This image was taken under a 2/3rds moon and the object was very low in
the sky by the time the clouds had cleared for a little while.

LRGB 10 10 10 10

Using a magnificent TEC180mmFL(the best scope I have used) Apogee U16M camera
and Baader LRGB filters. From my dark site in NSW Australia with kangaroos
on my property.

2 Corona Australis AP140 and TEC180

Posted By Greg Bradley
As it turns out I imaged Corona Australis under similar conditions (the TEC was under a 2/3rds moon though)
but weatherwise it was similar, same location, same camera (Apogee U16M), same mount, object was a bit higher in the sky for the TEC. The AP shot was taken 31 May 09 the TEC 26 July 09

Both are short exposures as both were cut short by bad weather but its an interesting exercise to see the same object with 2 of the top refractors in the world.

As you would expect aperture rules and the TEC shows more detail but the AP has a very pleasing and equally sharp wider view.

The processing is much the same and exposure time a little longer with the AP (40 mins Luminance versus 20 for the TEC).

Both are stunning scopes. Both are oiled triplets. The AP is FPL 53 and the TEC is Schott Glass Fluorite as the main element.

NGC300

Posted By Greg Bradley
2 nights of good seeing - I feel like I won the lottery!

This was taken on one of them.

A crop from a wider field image - Apogee U16M and Tak BRC250.

NGC300 a southern galaxy a bit like M33.

Rho Ophiuchi Nebula

Posted By Greg Bradley
I've been trying to image this one for a year but seemed to get thwarted by
weather too many times.

Finally a break and I got the image.
