STX Eta in H-Alpha light

[Peter Ward]

The 65mm filters arrived...the rain came down.....but finally some data

My goodness.It's all there. Smooth & detailed.
Quality shot.

That's only 20 minutes!! :eyepop:
Got to be careful not to cut yourself on that detail, very sharp.

Any plans for a colour version Peter? the Ha lovely but colour would be drool material.

Nice Peter, now I can see where I have to extend my mosaic.

That AP155 is a nice scope, pretty much a perfect match for the STX?

Cheers

Cool - I was comparing the field with the hyperstar mosaic I started and looks like you can capture in one panel what I need approx. three to do. I can't wait you guys start doing bi mosaic like Orion area or the LMC with your big sensors. Should be quite a treat. I know, I know...it's cloudy. :)

[TrevorW]

Very good detail for 20 minutes like to see the result of something longer

[Peter Ward]

The weather was not co-operating....but I did get some ropey colour data..
which can be seen here

I would have liked to have tested the camera with my AP155 TCC at F5.3.. no adapters are available yet, but AP have indicated they will be providing a solution in the next few months.

[Omaroo]

Glorious - both.

[Peter Ward]

Thanks Stu.....the STX with 65mm filters+wheel is a bit of a beast but certainly works well with the AP155, provided you have AP's 4" focuser/flattner. The KAF16803's extra 20% or so QE in H-Alpha, compared to the KAF11002, is quite noticable. The chip looks noise looks lower as well.

It will take me a while to work out the optimum exposure times for an RGB sequence, as both the sensor QE and filter transmissions have changed from my previous rig.... all good fun! :D

[Martin Pugh]

At last!

good to see you up and running Peter.

Lovely image.

cheers
Martin

[Peter Ward]

Thanks Martin :) The STX is a bit of a monster, and despite a few teething problems I can see it producing some excellent results.

BTW, do you still have the test unit?

[renormalised]

Nice Ha shot, Peter :)

[Martin Pugh]

Hi Peter
yes, still have it, but it goes back soon.

I am waiting on some bits and pieces, and then I am going to set about commissioning a new PME with sidexside guiding, new obs PC, hubs and all sorts of other stuff.

cheers
Martin

Solid images Peter, sharp contrasty and pinpoint stars edge to edge - nice....but as a fellow AP EDF user though that ain't nothing spectacular heck the FF is designed to cover 6cm X 7cm so 3.7cm X 3.7cm is nutin man :thumbsup:

Nice to see what field I will get though, so cheers for that and now I wont need to image the dreaded Eta to find out :scared:

...if I ever get out to actually use my FLI 16803 I will be stoked :rolleyes: :bashcomp:

Mike

[Peter Ward]

Thanks Mike...the Eta "standard candle" is pretty hard to pass up.

I recall when I ticked the (not inexpensive) AP 4" FF option, asking myself: will I *ever* need this thing?? :D

I'm sure you'll have the FLI-cam pumping soon. I'll be of the country shortly.....so the weather is bound to be great!

[Octane]

Peter,

Both of those are stunning. Interesting to note that there isn't all that much hydrogen alpha and colour data yet the image is striking as is.

Cheers.

Nice test image but again quite dull. My guess is its the light pollution.

Should have more vibrancy.

Greg.

[Paul Haese]

Man what a huge field. Heaps of sharp detail and the colour version when completed should be amazing. Well done.

[Peter Ward]

Bland? I'll agree to disagree.

Are you comparing

to

No problemo. Vive la difference! :)

[Hagar]

Nice images Peter. Great for such short exposures. Looking forward to something with extended exposures.

Be nice kids.

[wysiwyg]

Great result Peter!
I'm just waiting for some moonless clear nights to start doing my colour subs.
