Wow, great image with lots of details and all that in under two hours!
Thanks for the lovely view

Not sure your getting a lot of value from an AO-X at 1160mm (??). I only ever needed to use my AO-L at F11.7 on my Tak.

Cheers, Marcus

PS: And thank you for not giving us another B&W standard candle.

Provided you can get a 5-10Hz guide star, I find the AO-X does tighten stars up even at 1160mm..

and OK... but are you *sure* you don't want to see the H-alpha version

What is your sampling with this setup?

Sorry to say, some errant pixels were seriously harmed with Photoshop to smooth out the 1.66 arc/sec per Pixel data.

I am going to say you would maybe on need another 4 hours or so in Ha and maybe even another hour in each colour for it to really smooth out. The TSA would be 40 hours.

An OS RHA?

Aren't they f3.0? Careful what you wish for....

Thanks Steve... the reality will probably be the weather making the extra data decision for me.

Always a pleasure Alex... I figure if you have chimed in, it's probably a keeper

Well, not too shabby maybe. Thanks...

That is truly astounding, Peter. Considering both the short exposure duration and your light-polluted skies. Something to aspire to!

You're giving me inspiration to move my gear from my dark sky setup (where I just can't get out to nowadays, due to work, life, etc.,) and moving it to my light-polluted Queanbeyan backyard. I might actually get something done from the backyard! The STL/FSQ is sitting there doing nothing. I haven't done any deep sky imaging since my M31 several years ago. *sigh*

Yes Pete they are F3.0 I am not going to put something huge on one though.

That clearly does not work.

No H, all you need to do is go remote. Very simple in the end, once you bug hunt a few things. Just remember you can image while you sleep out at your dark sky site from your home. IP Switching is the most important tool you will need. I took Freds advice.

Octane (Humayun) · #28 05-02-2014, 01:35 PM

The property that my gear on has no Internet. It's not a proper observatory, either; I have to go out there and remove the covers, etc.

One day, when I'm all grown up and have some money, I might look into it. At the moment, it's either sell up or bring it home where it'll get used.

In that case I'd definitely say bring it home H, it's not all about having dark skies.

If it's in your own back yard then you'll get to use the gear, tinker with it, do some imaging = have fun with it. And you can still take great images from light polluted skies as Peter's image shows.

Thanks H. Queanbeyan light polluted?? Nah!

The thing to remember with urban imaging is provided you can keep the noise down (read: cooled CCD), deep objects are very attainable...they just need more exposure than a dark sky site.

Also the RHA is going to gather photons over 4x faster that a 100mm refractor...hence to get a similar S/n you'd need 4:1:1:1 hours with the Taka... certainly doable over a couple of nights

Octane (Humayun) · #31 05-02-2014, 03:59 PM

I have no qualms with doing multi-night imaging, Peter! You'll recall my first image with the FSQ/STL combo was Eta Carina captured over 6 nights.

I think I might just do this once I get back from my trip.

Thanks for the inspiration!

If you are where I think you are (Iceland? ) you'll need no further inspiration

Octane (Humayun) · #33 05-02-2014, 04:55 PM

I'll be going next Friday.

Most excellent!!

Iceland is awesome.

For Aurora, bump up the ISO to 2000.
Use glass that works well at full aperture, keep exposures to 1/2 sec or faster if possible...they move surprisingly quickly

I'd go there again in a heartbeat.

Gorgeous image, Peter. Lovely.

This is now IOTW.

Really very good. Love that scope.

Joshua Bunn (Joshua) · #38 10-02-2014, 04:09 PM

Really smooth and i like the colours Peter. You sure make the most out of your location.

atalas · #39 10-02-2014, 06:24 PM

Very good considering only 1.45 hrs and shot from crappy Sydney!

Thanks Josh... cloudy here now...but much more data is on my hit list.

The largely h-alpha component is pretty much immune the Sydney's light dome... and sure, more/better/saturated colours are going to need much more exposure..... but getting back to the H-alpha....as an encore:

Here is a crop of the H-alpha data at close to full res. (sorry Marcus

)

( ...have to say I'm pretty pleased with the RHA + AO star sizes

)
