A capture of M101, Pinwheel Galaxy, using Atik Infinity Mono with Explore Scientific ed102 scope
May 1, 2017 03:03:32 #
Last night, I posted an image of M101 using a Rokinon 135mm f2 with the Mono Atik Infinity. Tonight, got out the Explore Scientific ED102 scope. This is from a stack of 11, 60 sec each. I used wbana's advice and left the black and white slides all the way out so that 16-bits of info was captured. With 16-bits, stretching in Photoshop was easy. Final touch up in Lightroom.
The Explore Scientific ED102 is a scope with a FL of 714mm and is f7. The objective is 102mm. Considering the size of the Infinity sensor, its crop factor is something like 4.5x, thus the field of view works out to be somewhere around the same as a 3200mm lens. Did not use guiding, but polar alignment was close enough that I was able to at least track for 60 sec without seeing trails. The Infinity SW autostacks the 11 images as they are uploaded to the laptop, and any movement from capture to capture is accommodated during stacking.
The 2nd image is M3, a globular cluster. This was a stack of 5 for 60 sec each.

Adding a portion of the Virgo Galaxy Cluster taken tonight.
Would have needed to reduce focal length to see more of the Galaxy Cluster
Also Adding M88 which is part of this group.
It was so clear tonight that everything I looked at was coming in clear.

Adding M51, Whirlpool Galaxy and M63, the Sunflower Galaxy.

Adding M53 from last night. M53 is about 53,000 light years away, or about 1/2 the distance across our entire galaxy. M3, previously shown above, is a lot closer at 33,900 light years away. At this greater distance, this globular cluster doesn't quite have the same detail as M3.

WOW Jim that's one fine Cluster of shots all in one post.
They are all really great works. I spent Sat night looking visually
at most of these and quite a few others. The wind was too high
for any photo work up on the mountain.

Thank you Craig. Incredibly clear night. The moon was in the west, but I was shooting east, and had no problem with it. But that old moon will be getting higher and higher now.

Those are all beautiful Jim!
You are quite the star hopper there, Grasshopper.
I'm just bedohdillin with Bode's tonight.
DSLR is doin it's thing with my 180 mm macro for a try.
OK, back to fiddlin...

Yes, bwana changed the way I capture, and the results are night and day difference. Was having fun last night. Anything I went after came in clear. Evan had a tree between me and the moon, so it has not affecting me at all.

Most macro lenses work well for astrophotography. Good luck.

I hope now that you have the settings you like that everything comes in clear.
Looks like that telescope and the Infinity were made for each other.
My macro lens experiment was quite a bust.
The leaves of the ivy were sharp as a tack, but beyond was a large faint orb. I'm pretty sure it was Polaris.
But I don't think Polaris is supposed to look 4" in diameter....
If at first... I'll try and try again.
My Macro lens is very big. 180 mm. I got that so I would have a longer focal length from tiny creatures.
It just so hard to tell out there in the dark.
And no, live view doesn't work in 'Manual Mode'.
But I have fun, and laugh a lot...
The attached picture is typical of my captures with the Macro. I did a down and dirty Brightness and Contrast in APSE12 just to pop Polaris.
But I think my better shot is the wide angle.
(Thank goodness I didn't waste a whole night on the experiment.)
(Attach a file isn't working. Times out.)

So sorry it didn't work. Inability to focus is a real bummer.

My thoughts also. Even after heavy stretching in Photoshop, there was so little noise. And what little there was, I dealt with in Lightroom.
But what I am really finding is that the sensitivity is unbelievable. I can't begin to compete using a DSLR in this area. I can do in minutes what takes much longer with the DSLR.
The only downside is the pixel count. Only 1394 x 1080. But that also means that the pixels are quite large, 6.45x6.45 um, and can hold a large charge.

But really, for the web don't they have to undergo jpg compression anyway?
So having a 50 mega pixel camera sorta becomes a moot point.
