The sky finally cleared long enough to capture a quick image of Eta Carina in Ha. Maybe we might get some clear nights here over the winter months and I might get to try this camera out a bit more with the Tak and RC.
I've added two images to the screen . The first is a straight RGB of 25 minutes per colour. I seem to need to tune my polar alignment a little as I did suffer some field rotation between shots but have now found the control in Maxim which allows a group of say red images to be collected consecutively instead of one of each colour in turn. This may help a little.
The second image is a combined image using the Ha as a luminance channel. My problem here is getting the colour good without changing it to a nice salmon colour during the blending.
Any help will be appreciated.
Image details:
Telescope: Takahashi FSQ 106ED at F5 on Losmandy G11
Guiding: QHY5 with WO 70 mm
Camera: QHY9 with Baader 7nm Ha filter.
Exposures: 6 X 10 minute exposures
Processed in IP 3 and Photoshop CS4 64 bit.
Nice big fov there doug. Do those 106's have a 4" focuser? How do you attach the wheel?
Hi Robin, Yes the 106 has a 4" focuser but it also has a stepdown to the standard Tak 62mm adapter. I connect with a standard camera adapter but also have a Tak 35 Camera adapter with both a T thread adapter and a 54mm adapter which when I get around to fitting it will make a fixed screwed connection.

Thanks Darren, I suppose one night counts but it is cloudy again. Surely the drought has broken! It has up here anyway. Still it is nice to get out again.

wow, huge detail there Doug, the technicals are all excellent, apart from a slightly blown core. Smooth, low noise, sharp as and very smick guiding.
Cant put my finger right on it, but the dynamic range seems possibly a tad high (cause you could, clean data would encaurage that ;-). RGB would mitigate that effect. Are you going to add colour?.
Doug, that's sensational. Really like that. 7nm seems like a really nice filter.
This weather is driving me nuts! Glad to see you got out there and got a bit of exposure happening.

Thanks H. Been dificult weather wise and I guess it's not going to get any easier. Have a great trip to NZ, mate.

G'Day Gray, Warming to the camera. Just need some exposure time to get things going better.

When I finally get a good image I will post a high res version for sure.

Thanks Fred. Guiding is easy when my focal length is only 530mm. I may have a bit more trouble when I try it at 1600mm.
This whole thing is just a big learning curve again and I do seem to need some help. With time I am sure I will get the hang of it but helpful feedback like this is always a great help.
Thanks Fred.
Very nice Ha Data Doug. I would move the levels towards less contrast and lighter tones but that's personal taste. I think you did a great job on the blend color wise. It's always a challenge to register the tighter Ha stars with the bloated RGB ones. I usually use noel carboni actions to tighten the RGB stars prior to blend the Ha as Lum layer. I also use the reduce noise feature in PS to tone down the resulting blue rings in the final. Works a treat. Great shot.
Another Eta in Ha RGB Added Help needed.
