Nicely done on all the images. Ha produces really contrasty images and with the addition of a S and O filters and you will be producing narrowband images from Sydney.

Thanks Paul.
My next step was going to be RGB, but being stuck in Sydney it might be S and O first. Either way, I have a lot of learning to do.
Results to be proud of Ross. Very nicely framed and it seems like your scope and the QHY9 are a perfect match!
Thanks Ivo, glad you like them.
The QHY9 and my scope seem to be producing decent shots. I'm also experimenting at the moment with an old Nikon 180mm lens on the QHY9.
I've only had a chance to try it out once because of the weather, but it looks promising for some nice widefield shots.
Bad news first... the objective of your WO scope has a high frequency polishing error (evident by the banding and spikes on *really* bright stars in the HH image )
Good news.... Guiding and camera S/N are spot on and you can rest easy that your system will deliver very good results.
Things to do:
1) more data (if you live near Sydney... forget it for now )
2) add colour
3) have fun!
Monochrome with Ha seems to be the best way to get a decent astrophoto in our area. Shame it can't see through these rain clouds!
The QHY9 would be a great combination with your telescope and mount.
Thanks.
Ross.
Hey Ross all good here - I am about to start on a ROR obs in the backyard
so even if its cloudy I can sit in there and at least think I am doing something Your Ha looks fantastic I hope to go a mono ccd sometime later in the year if I ever see the sky again !
Congrats Ross - stunning mono CCD debut shots
You'll have a ton of fun with the QHY9 I reckon - a great piece of kit (then again, I'm biased.....)
Thanks Rob,
I am pleasantly surprised with the results, but I do realise I have a lot of intense learning to do before I can produce colour.
I will enjoy it.
I also have an 8 inch Newtonian, but I just cannot get round stars from it on the HEQ5Pro mount, no matter what I do.
The adapter ring arrived in the post this afternoon....thank you.

Hi Peter,
Thank you for the good advice and your encouraging comments.
I certainly am going to have fun getting the most out of the QHY9 camera, including doing colour.
The WO scope is it for the next year or so, but I'll push it to it's limits and get the most out of it.

Glad the adaptor arrived intact.
Yes, flexure can be a challenge for Newts. You certainly seem to be on to a good combo here Ross.
You've made a great start in narrowband, Ross. Look forward to seeing more!
Cheers,
Rick.
Hi Rick,
Thanks for your kind comments. Glad you like the photos.
I have managed to attach an old Nikon 180mm lens to the QHY9, so a few widefield shots are on the way.
I tried a Ha clip in filter in a modded Canon 350D last year and I got good results.
However, I don't think you will get much if your DSLR is not modded.

Yes - modded would be a lot better & would open up Ha.
I am dissapointed with my unmodded EOS 1000d camera -
it just doesn't give good results in summer.
I think the noise doubles for every 7 degrees rise in temperature.
Those cold nights in winter when I am out there with 4 jumpers on,
a scarf, a beanie, gloves & hot drinks at least give me some decent signal to noise ratio.
Great Ha shots Ross. Adding to these with O111 and S11 so you can do narrowband images would be the go.
A slight amount of coma in the corners. Either spacing of your reducer is off or you need a flattener. Usually a reducer and flattener are 2 different things. Reducers sometimes will give elongated stars in the corners if their corrected circle is too small or the spacing is wrong and flatteners should give round stars to the corners with the correct spacing.
