M42

Posted By Greg Bradley
Its Orion Nebula time again. Reasonably high in the early morning.

Tak BRC250, FLI ML8300 at -45C, Astronomik filters.

LRGB 44 24 24 24 core is a composite of 5 x 15 and 5 x 30 second shots.

NGC1935 LMC Superbubble in Ha

--------------------------------------------------------------------------------

I took colour for this one as well but it looks best so far in Ha.

5 x 10 mins, 5nm Astrodon Ha, Microline 8300 camera, Tak BRC250
from my dark site.

2 versions of M45

Posted By Greg Bradley
I imaged M45 recently plus I imaged it around this time last year with the same scope (Tak BRC250 and Baader LRGB)

Latest was taken with a FLI PL16803 and last years was with an Apogee U16M (Astronomik LRGB) so they
are the same size image.

Here is the latest version:

LRGB 50 60 40 40:

Last years and this one combined:

LRGB 110 90 70 70:

FWHM figures were much much lower in the latest version like 1.7 to 2.2.
Whereas the earlier year its more like 6-9FWHM. Perhaps I hadn't yet installed
the FLI PDF when I took last years image and the focus was a touch off but
I see the Baaders have less reflections than the Astronomiks so perhaps it is
more to do with the filters?

No doubt the seeing was also better but not by that sort of factor.

NGC6589 with Ha added

Posted By Greg Bradley
I shot this about 2 months ago. After seeing Thomas Davis's magnificent
version with Ha I decided to shoot some Ha and add it to the image.

It brings up more of the colour in this region.

HaLRGB, Apogee U16M and Proline 16803, Tak BRC250.

Thors Helmet in bicolour

Posted By Greg Bradley
I took this recently during an almost full moon.
TEC180mm fluorite, Astrodon 5nm Ha and O111 filters.

FLI ML8300 camera. Remote NSW Australia.
90 90minutes

I have 6 hours of LRGB I'll be adding in a later version
that I took earlier in the year.

Vela Supernova Remnant

Posted By Greg Bradley
Here is my latest image through my TEC180FL and a FLI Proline 16803 in Astrodon 5nm narrowband
filters.

Part of a vast area of gas and colour in the Vela Supernova Remnant in the Southern Hemisphere.
Taken in remote NSW Australia. Good seeing.

Vela Supernova Remnant another look

Here is another narrowband image of part of the Vela Supernova Remnant in the southern Hemisphere.

47 Tucannae

Posted By Greg Bradley
Always an impressive visual object but it can be elusive to image
with its intensely bright core. Over a million stars in this one.

Vela SNR with AP140 and reducer

Posted By Greg Bradley
Here is one of my favourite Southern objects - The Vela Supernova Remnant.

This one was taken from my new home which has fairly dark skies and my
AP140 with its fabulous 155TCC (reducer /corrector) that gives F5.7
over a very large field.

FLI Proline 16803 and Baader filters.

HaLRGB 30 30 30 30 30.
