First Light QHY10 OSC

[Hagar]

This is the first image taken with my new QHY10 OSC camera. A very quick exposure to see what it can do. A total exposure of 70 minutes of M20 taken last night through my Tak TSA 120 at F7.5.

I have bought another OSC to use during the short summer nights when with work and family committments I just don't get enough time to produce an image with the mono camera.

This image is a crop but one thing evident with this slightly larger CCD is that I will have to get the field flattener up and working with this scope.

Thanks for looking. Your comments are very welcomed.

Very nice image Doug, I cannot fault it in any way. If I ever progress from the DSLR, a OSC CCD will be my choice also because of limited time with work and other commitments. All the best.

[CoolhandJo]

Great detail. And so mucher quicker and easier than mono lrgb work. :)

[atalas]

Looks great Doug.

Hi Doug

Great image, colour balance looks nigh on perfect on my monitor. I run a TSA120 with a ST4000 and dont seem to need a flattener. Are you sure something is not slightly out of square? The stars in the corners look slightly elongated but the direction appears consistent in all four corners? Of course there may be scope to scope variations as well

Please keep in mind I'm no great expert on these things.

Cheers

Lars

yep, looks the goods mate!

Good looking first light Doug :thumbsup:

[Alchemy]

Aint it just the way, I move on to a mono hoping for better detail.... And you go putting this up from a OSC . You make it all look too easy Doug.
Lovely resolution, colors are great.
I can sure understand the logic of a OSC particularly here in Victoria where clear nights are at a premium, you have to make the most of what time is available.
As long as we all enjoy, that's what counts, and it looks like you will have a ball. :thumbsup:

[RickS]

Looks very nice, Doug! I see a bit of the same bright star bloat that my QHY-12 produces, but it's not too bad. Certainly better than getting only a handful of mono frames before the clouds close in...

Cheers,
Rick.

Nice image, Doug:). Looks like the little QHY10 is going to perform really well:)

[h0ughy]

love it Doug - i still have my qhy10 BNIB unopened as i have it to use with the C11 hyperstar i have. I must get it out to use as i have had it now for nearly a year ;)

What software you using to acquire and process images from your qhy10?

[Hagar]

Thanks Lester. It is certainly much quicker than the mono camera for capturing a reasonable image. In fact I sometimes think the only real difference is a little bit of resolution.



Thanks Paul



Thanks Louie



Thanks Lars. The difference in the full frame is quite evident. Fitting the 35 flattener in a screwed together setup will take some work.



Thanks Darren



Thanks Marty



Clive it is a bit of a battle working out which way to turn but I am sure with time I will use and combine both cameras.



Thanks Rick. If only we could control the weather. Maybe we can put a tax on clouds and they will go away.



Thanks Carl



Thanks David, be brave and get it out of the box.



Thanks Chris. Software: I capture with MaximDL, align,combine and calibrate in ImagesPlus and final processing done in Photoshop. I must give CCDStack a go with the OSC.

[ReaPerMan]

Hi Doug I have just gone through the process of using CCDStack with my QHY10 and I used the OSC chapter from Adam Block's "making every pixel count" CCDStack disk. His premis is that using the OSC for easier "aquisition" but then debayering into seperate R,G & B and creating a L produces better results. I've tried it and it does work. It also allows you to correct any colour imbalance in the RGB matrix. I found that sometimes the QHY10 was a bit "shy" in the blue so this process allows it to be corrected at the source.

Love the M20, If I can chase the clouds away I might actually get a first light with my GSO RC10 and see how the QHY10 comes out with that.

All the Best

Paul :thumbsup:

Good stuff. Have you tried to combine the QHY10 colour with a LUM from the 9?

[richardo]

This looks great Doug...!
Certainly beats messing with filters...
Now one night you'll be getting a colour image you can use.
The next if need be, you can collect mono for lum with your qhy9..

I know a few other imagers that go this route ..

Or even have two scopes, your two ccds and a mount to take them and you'd be getting everything in one hit!:question:

Rich:D

[Hagar]

Thanks Paul, I just reprocessed this using CCDStack and maintain that IP does just as good a job at this stage,. I will have to try a bit more work on this but as it stands at the moment IP will do me.



Thanks Mark, I haven't tried this yet but will need to use Registar when I finally get around to trying this.



Thanks Rich, Interesting thought but I only run the one mount with one scope on it at a time. Maybe down the track I will either upgrade the mount or get another which would be easier for me in the long term.

[multiweb]

You can use CCD Stack for that. Debayer all your subs to separate channels then stack all the subs to the lum. When you do your color combine everything will be aligned. Use the CCDIS star pattern matching algo as it supports different image scale. The default star match works only with subs that have the same image scale.

[jjjnettie]

Good stuff Doug. Looking at purchasing that camera myself.
I've got RickS's qhy12 on loan atm, and had all sorts of dramas with the capture software. Using Maxim and EZcap.
Maybe I should persevere, ummmm, Rick, when do you want your camera back?

[RickS]

Jeanette,

I gave up on EZcap, but Maxim was working well for me on the QHY-12.

No rush to return the camera. I'm happy with my SX mono for now. I'm planning to use the QHY-12 for wide field work with camera lenses but I haven't picked up the adapters and stuff I'll need yet...

Cheers,
Rick.

Hi Doug,

The shot looks good.

A OSC is such a productive tool when you have limited time.

It would be interesting for you to compare the same object taken with both cameras and see how much difference in quality there is.

Thanks.

Ross.

[iceman]

That's a nice trifid, Doug! I like it!

[SkyViking]

Very nice, congratulations on first light :)

[Hagar]

Thanks Marc, I have tried this but found the results were really no better using CCDStack. IP does do it very easy.



Thanks JJJ, This camera does seem to do a very nice job. I just need a bit more time and some clear skies to test it a bit further.



Thanks Ross, The OSC does seem to capture a lot quicker than the mono and the overall result doesn't seem much different to my old eyes. I am looking forward to using this during those short summer evenings.



Thanks Mike.



Thanks Rolf.

Doug,

When you debayer your QHY10 what color balance settings are you using in the RGB matrix?

Ie 1:1:1 or different ?
