NGC281 Tri-Color Narrow Band

Posted By Jason Boyce
Nice work Floyd,

I really like this in the Hawaiian pallete.
So,so, transparency may have robbed you of some nebulosity but the result looks very good anyway.

Narrowband imaging sure gives a whole new meaning to "more data" doesn't it?

Saturn

Posted By Jason Boyce
Thats a tough target you picked there Charles!

Boy do I here you on the seeing,I get plenty of poor seeing over here on the East side of the mountains.Good seeing would be a must to get detail on this one!

The color looks pretty good to me,I have visually observed this on a couple occasions,it appeared very Blue and bright.

Did you try any deconvolution on this?that may tighten up the stars some.

Nice job under the tough conditions,it looks good!

Looks good Jim.

Some nice little structures in this one.

4 new shots from the weekend

Hi Ivan,

That's a productive weekend!
Nice group of images,I like them all but I think my favorite is the Horsehead too.Never tire of images of this one.

Well done!

vdB 31 and some Barnard objects

Hi Tom,

I just love these dusty areas you go after! Beautiful image of this not often imaged area.

I had my first real dose of winter this weekend,in the form of snow sad

Best Focal Ratio for Imaging Under 4.5 Mag Skies?

Posted By Jason Boyce
Hi James,

While I have never used an astrograph I don't see why it would be better to use a slower scope in light polluted skies.The ccd is just counting photons whether they are in the form of light pollution or the object you are shooting.A faster scope should just mean shorter exposure times to get the same signal to noise.

I shoot in skies that range from about 4.5-6,depending on which direction I point my scope,there is always light pollution present in my subs sad
I have found more exposure time,better "signal to noise" helps to make it easier to deal with.

A fast scope would be ideal for narrowband imaging.

ST2000xm vs. ST10xme

Posted By Jason Boyce
Hi Joe,

I have owned both cameras and made the same upgrade you are considering. I was pretty happy with the ST-2000 but wanted the added sensitivity of the ST-10,the difference in my opinion is well worth the investment.

The blooming took me some time to get used to dealing with,software makes it easy to remove but sometimes may leave some artifacts,at least on my images. You can also take shorter exposures that are not bloomed to add in to the stack to take care of severe blooms.
The only difference in processing would be the bloom removal,I do mine right after calibration.

It's probably not the best choice if you are looking to shoot bright star clusters and such but if you want to go after galaxies and nebula it is great,especially good for Ha!

I really can't think of much of a reason not to recommend it over the ST-2000.

A Kaleidoscope of Southern Dust -- CG4

Posted By Jason Boyce
Tom,

Another stunning image you have produced here. There sure is quite the assortment of color in the dusty areas.You should start your own catalog of these unknown dusty areas.

Mel66 sure is pretty in this too.

Hey,is that the Millenium Falcon I see in the lower left corner?!

Wow,that is a lot of HII!

Fantastic job Tom,it is magnificent.
