A few images taken with SDM Dob

[rogerg (Roger)]

Wow. I'm stunned at what you're getting for subs of less than 15 seconds. Such light gathering capability. Amazing.

[norm]

That's very cool stuff Alex

I assume your SDM has servocat installed ?

Man, its damn good!

Cheers, Norm

[alexch (Alex)]

Thanks again, guys and gal! I was overwhelmed when I saw all the colours after 10-15 second exposures on the camera screen and now I am even more overwhelmed by the warm reception of my humble short-exposure deep-space attempts here.

I've been concentrating on ultra-wide filed astro-terrestrial images but learned a good deal of how deep space images should look by browsing some brilliant work in this forum.

Cheers,
Alex

Thanks, Norm.

Yes ServoCat and Argo Navis come standard on SDMs larger than 20"

Alex - your pics are seriously impressive! Well done.

Unbelievable
The way of the future I think. Big scopes quick exposures aperture rules big time. More and more people will be doing this with there motor driven Dob's.

That 5139 is just like in the eyepiece and 5128 awesome

Great work Alex

[Scorpius51 (John)]

Not too shabby at all Alex! I'd be right chuffed with those pics. Wouldn't mind the 'scope, either! Good one

Cheers

Alex, does the CMOS chip have the filter on it ???

[Paul Haese]

Looks great. Impressive results for sure. 22" of aperture is always going to rule. Nice.

Yes - like a stock DSLR.

Thanks, Dave. We need a good night at the Briars or Heathcote so you can look through the eyepiece

Thanks, John. I am surprised how well they turned out.

Thanks, Paul. It sure does but only until it is overruled by ... say ... 32" ?

Alex, I might have missed it, but are you fitting shorter truss poles to bring the camera into focus?

No I use the longer visual poles. Paracorr helps to bring focus a bit forward.

[erick (Eric)]

Visual and photography with the same poles - that is neat! They are very nice images, Alex - and such short exposures! Aperture rules, yet again?

[strongmanmike (Michael)]

Lovely little collection of snapshots there Alex! Drive-through imaging

That camera looks very similar to my el' cheapo...well they are both black

Mike

[asimov (John)]

I'm that impressed I had to come back for a second comment or two!

These are just too good to go past, for the mere fact that they are 15 sec. exposures. Gotta love that extra aperture. I can only imagine 'going deep' & pulling REALLY long exposures of a whole 30 secs!!

[Jen]

wow ALex they are amazing pics in such a short time just gorgeous

[alexch (Alex)]

Eric, Mike and Jen - thanks heaps!

I forgot about the three 10-second subs of NGC3242 (Ghost of Jupiter) I took the same night.

When processing the images today I noticed a few fuzzies in the image that look like galaxies nearby (in 10-second subs!).

Attached are the normally processed image and with exaggerated levels to show the fuzzies. One location matches a spiral galaxy at the left of this beautiful image:

These are unresized crops of a full size image.

Cheers,

kool Alex yep i can see the fuzzies
