NGC 896 Today and Two Years Ago

Posted By Greg Bradley

Hi Dennis,

Yes, great progess.

I see you have used an SXV-H9. That is the monochrome version right?

I have been evaluating if a SXV-H9C is a good choice for another imaging camera for me over a better DSLR.

Modded 20Ds are very nice as is the 20Da. A modded 350D XT seems very cost effective. A modded Canon 5D is attractive as it has a 35mm film sized chip and very low noise.

Of course the SXV M25C is a competitor to that as a cooled 35mm sized one shot colour chip, albeit at much greater expense. And of course perhaps just use one camera and make that the STL11000XM is yet another alternative!

Comments?

Oh my god, what a wonderful image. One of my absolute favourite objects. Also look how much extra is shown in the white disk than is normally seen. Just wonderful. Thanks!

Rosette Nebula from the NC Blue Ridge Parkway

Hi Ivan,

The stars on the left seem slightly out of focus yet on the right they are very sharp. It may be your camera was tilted with regard to the optical plane. Sometimes DSLRs sag in the visual back if there is any slop in the fittings. Ideally a screw fitting into the Tadapter would help.

Also 6 minute shots should show a lot more red in the nebula. If your camera were modified it would be a huge difference in Ha response and those 6 min shots would look more like an Sbig shot.

Still a very pleasing shot though and well done on braving the cold. You are right, the cold makes a large difference to the noise of the camera. Especially a modded one.

Greg.

M35 & NGC 2158

Fantastic shot Ivan. It looks like you're looking out of a spaceship's window. Very 3D.

Did you need to use noise reduction or take darks? It seems to have no noise in the shot.
