M33 - another one from SRO

RickS (Rick) · #1 26-01-2015, 11:44 AM

M33 in LRGB. Data captured from SRO in California. I have some Ha as well for a future repro

Scope: FSQ-106ED
Mount: Paramount ME/AP900
Camera: QSI683
Filters: Astrodon Gen II LRGB, 5nm Ha, OII, SII (1.25")
Guiding: QSI OAG + Lodestar
Image scale: 2.094 arcsec/pixel drizzled x2
Exposures: 17x900s L, 8x900s R, 11x900s G, 13x900s B
Processing: PixInsight

It's a lovely object and I hope I have done it justice.

Bigger version here: http://www.astrobin.com/151279/ The IIS site compression doesn't do any favours to the attached version.

Cheers,
Rick.

Nice work Rick! The full res is very good and the one to check out. Addition of Ha data should add some nice touches to the galaxy.

Justice done.

Thanks, Rod!

Stunning, as we've come to expect Rick!

When are you going to run the PI training course??

Great looking image Rick

I like the contrast and almost cream coloured central area, crisp looking too, nice.

Nice and subtle in the reds. Maybe doesn't really need Ha

Thanks, David. I thought I'd try to do a PI intro one weekend before we start to get into better imaging weather but I have been waiting to find out about some family and work arrangements. I'll see if I can schedule something in March, perhaps.

Thanks, Geoff. I think I'm going to struggle to add Ha in a way that improves the image. That's probably why I haven't tried yet

Cheers,
Rick.

That's a nice shot Rick!

DJT (David) · #10 26-01-2015, 06:02 PM

Great detail and a fine image. + 1 for a PI workshop..no pressure 😀

Paul Haese · #11 26-01-2015, 06:16 PM

The colour is great as well as the detail Rick. I think I especially like the dust lane detail.

gregbradley · #12 26-01-2015, 07:15 PM

A sensational image Rick. Really nice.

Greg.

Thanks, David. I was planning to do a small hands on workshop in Brisbane for some of my AAQ colleagues but maybe I'll have to consider a roadshow

i haven't heard from Vicent for a while so I'd say his workshop in Australia is postponed for a while at best.

Beautiful Rick - love the dust detail. I think you definitely have done it justice.

Cheers

Great image Rick. Congrats.

All the best,

Wow, what a stunner Rick.

Have been hanging out to see this, after struggling with how to process a few hours of M33 data from 10Chain before Dec hols, and this is a reference pic of the beast IMHO.

Congrats on making such good use of your SRO data!

Thanks, Rob. The SRO data would give me an unfair advantage

What a beautiful M33 photo Rick.

Sharp, great colours and what amazing detail!

Ross.

Superb Rick!

Assuming you added the spikes?

Cheers, Marcus

Thanks, Marcus. I believe the spikes are caused by the KAF-8300 microlenses. The QSI-683 produces them as did my SX H-18 camera and I often notice them in other images from cameras with this sensor. My process for reducing big stars appears to make the spikes more prominent. Fortunately, I don't mind them

Cheers,
Rick.
