Hmmmm. hadn't heard that about the CGEM. It's been wonderful for my needs.

Hi Milby,

All looking extremely good ! :bow::bow: I particularly like the "Leo Trio" !

Tell me this though; noting your earlier excellent image of NGC 7000, (The North America Nebula), have you thought of additionally using Ha or Olll particularly where such nebulae are concened ? (I presume they work with colour cameras such as yours) ? :idea:

Best regards,
Tel

Tel, thanks for the kind words. Yes, I have used H-alpha and O III filters and posted some of the results in the Nexstar graduates thread.

Another nice image, Milby ! :bow::bow: A UFO ? :lol:

I've been looking around recently for inspiration as to what next to attempt and you've just given it to me ! :bow: I did image it back in 2011 but you've just reminded me that it's still there ! :lol:

In return, have you "tried" the "Blackeye Galaxy" (M64) in the same constellation ?

Best regards,
Tel

Hi Tel,

I do have some data from last week of M64. Hope to have some time this weekend to process it.

Cheers!

I have been impressed with the hyperstar and really have been thinking of getting a setup. Thanks for the inspiration!

You're very welcome, coinboy. It has its bugaboos, but definitely its advantages, too.

I have both Maxim DL and the capture software that came with my ATIK 428ex. Frankly I only use Maxim because its what is compatible with my autofocuser. Its so clunky and awkward compared to the ATIK software. So I set up the focus, and then shift to the ATIK Software for capture.

AFAIK the gain on the camera isn't adjustable, nor should it need to be. The various amplification settings you find on the software are just for the image, not the camera.

I've had no porblem at all with my C8se/Hyperstar/ATIK 428ex combination, so if it is frustrating you perhaps you can post some more details about the issues and maybe someone will figure it out with you. I have called Starizona for help setting up the focuser I bought from them - it turned out they had inadvertently included the wrong set of instructions, and also with the camera - which turned out to be fine but I didn't have the correct offset set up in Nebulosity - lots of nice blue pictures - the Picasso of astro-imaging! - and they always gave me all the time and help I needed to make it work. If your Hyperstar is frustrating you i suggest calling them and discussing it with them. I have NEVER encountered better Customer Service than Starizona!

(I posted this earlier in the "hyperstar is crude" thread that is in Cat & Casses, but thought it might be appreciated here as well. My apologies if you come across it twice!)

I don't consider myself an expert by any means. In fact I'm little more than a beginner having been in this hobby for a bit less than two years. For me Hyperstar has been incredible! There isn't another system that would allow you to get all of the following in a SINGLE NIGHT and with an unmodified Nikon D7000, all from stacks of 30second, unguided, exposures:

Cocoon Nebula: http://www.astrobin.com/full/21509/
Horse & Flame: http://www.astrobin.com/full/21521/
Double Cluster: http://www.astrobin.com/full/21523/
Trifid & Lagoon: http://www.astrobin.com/full/21525/
Omega: http://www.astrobin.com/full/21526/
Andromeda: http://www.astrobin.com/full/21528/
Triangulum: http://www.astrobin.com/full/21529/
Pleiades: http://www.astrobin.com/full/21534/
Orion: http://www.astrobin.com/full/21533/

Later I moved to a 60Da and got an H-alpha filter and was able to get this from my backyard which is a white zone:

Rosette: http://www.astrobin.com/full/32724/

None of this is going to get published, but I find it an immensely satisfying setup.

As a side note, I have never collimated my Hyperstar. Whatever it was set to from the factory I've used untouched.

Great "Hyperstar" imaging, End, with excellent scaling ! :bow::bow:

Could you tell me though, a little about your 'scope and mount set up ?

Also, have you any comments on the suitability of the NIkon D7000 or Canon 60DA for this purpose ?

Clearly from the above, both cameras work well with "Hyperstar" but, being larger in area than the "Hyperstar" lens, they must surely obscure incoming light to some extent......... or (?) :idea:

It was just that I was under the impression that DSLRs were not well suited to "Hyperstar" imaging for this reason. Obviously though, you've proved me wrong ! :waytogo:

Best regards,
Tel

Tel-If i'm not mistaken Starizona does not make a C8 hyperstar kit for a dslr or I would have bought one. You're right the camera's body would obstruct too much light.

end- outstanding images! :bow:

That was my impression, James.

It would nevertheless seem that even if the size (area) of the DSLR is, (as I've always naturally supposed it to be), greater than that of the "Hyperstar" unit, the obstruction it potentially causes still apparently permits more than sufficient light through End's 'scope causing no significant reduction in image quality.

The only thing we don't yet know is the aperture size of the 'scope used here and thus the ratio of its effective surface area to that of the camera's.

:idea:

Tel

I am imaging on a C11 (Edge HD, but that doesn't really matter). This is mounted on a CGE PRO, but with Hyperstar you really don't have to have such a large mount. I'm sure a CGEM would be fine. And as I mentioned, these are unguided images.

The DSLR does indeed increase the central obstruction and also makes the diffraction spikes a bit odd, but neither of these dramatically impairs the image quality. More recently (after these images were taken) I've started using a donut shaped piece of felt on the corrector to improve the diffraction issue.

Yeah a C11 would allow sufficient light to work with the hyperstar-dslr combo. I think you could use your Atik 314 Tel. :poke:

How's this: I know if I had an Atik 314 I would have already purchaced a hyperstar lens na, na n'na, na! :roflmao:

Hi James, Hi Peter,

If I could use my Atik 314L or Canon 350D, I'd first have to take a hammer to the primary mirror cell of my 'ol Nexstar 8i OTA to remove it ! :smashpc:

Tel

Don't think your getting off that easy. Starizona has a conversion kit for non-faststar secondaries. No hammer necessary.
