A Long time coming

By Peter George (Australia)

 It's been a long quarter of a century, or so… In the 1960's I grew up in Australia with the gleaming white domes of Mt Stromlo Observatory within the view from my bedroom window.  I wanted to be an astronomer. When later I started pointing my first small backyard telescope at the sky it was a matter of twisting and pushing in an effort to find and follow all those amazing objects of interest to a teenager with stars in his eyes. A star atlas came in handy too.

Lots of 'averted imagination' was called in for as I battled the Canberra cold, fatigue and local light pollution in an attempt to see those gems I had read about in astronomy books from the school library. Still, it was enthralling and addictive.

As my age and competence slowly increased I found myself wondering if there was a better way. The newly released 'Personal Computer' was an expensive elitist toy that seemed to cry out for an application that melded both my passion for astronomy with the fun and potential of the computer.

Alas only the world's major telescope observatories such as Mt Stromlo to my north, seemed to have the ability to match these devices. They provided ease and functionality to the astronomy pro of the automated point, track and shoot methodology. All with the pushing of a few buttons and the display of progress on flickering banks of B&W monitor screens.

I dreamed of my own 'Telescope Control Room'. Complete with a 'Cold Camera', which would allow me to capture those faint fuzzies and dim dodgers up there in the great southern skies. Many of today's younger generation of telescope users probably would not even know what a cold camera was!

 Time passed, much film was wound on, a few telescopes came and went, life became more complex and obligations drew me away from my love of astronomy and nailed me solidly to the work a day Earth. But I still glanced upwards at night whilst driving to work or admired a bright planet as it coursed over my weary head on clear and inspiring summer's evening. It was an ongoing nagging habit.

Then a friend and member of our local astronomy club told me about 'Global Rent-a-Scope'. He saw the puzzled expression on my face and we spent the next hour discussing remotely controlled telescopes and what this meant to city bound and cloud cursed astronomers on a budget. I was impressed and we both agreed to look into it together 'one day'.

Well indeed that 'one day' arrived for me late one night, when a  phone call invited me to test drive the iTelescope-008 12.5" RCOS remote telescope before it went online to the public. The telescope was many many miles from my home but I did not need to be asked twice! It did'nt matter!

 I logged into the remote observatory computer via my Internet browser and found myself slewing to M20 within minutes! The remote telescope slewed to my target, focused, picked a guide star and then awaited my next command. I ordered a 300 second Clear exposure and nervously hit the Acquire Image button. I waited as the system status display took me back to my childhood dream of that "Telescope Control Room" of my own. I was smiling a lot.

Soon a preview image was on my screen. It simply amazed me! There it was, the glorious Trifid Nebula on my screen, and you know what? It felt great. It was my best ever image and it was still just a monochrome picture. I had the color data still to come later that night. I couldn't help looking out my window to towards the dark peak of Mt Stromlo and shook my head a little in wonder. 

 I spent 2 hours gathering light that night from the comfort of my home, keeping a close eye on the B&W previews as they flicked onto my monitor and eagerly looked forward to downloading those RGB frames that would be the real test of my skills later. It was fun. I didn't have to battle with my own modest mount, optics and heavy urban light pollution. And though I love my own telescope its nothing like the equipment that was at my command at the other end of this remote connection. I felt like a pro!

Here was the synergy I had awaited all my astronomical life! A computer, the Internet, a first class telescope a huge CCD camera, and any imaging target at a whim. It was wonderful. And the final image? It made me very happy indeed.

Using the remote telescope network provided by iTelescope.Net has allowed me to use research grade telescopes without the huge costs involved in getting my own hardware, which would most likely spend most of its time sitting under Canberra clouds anyway!

My own telescope is a Meade 8" SCT and I love it. Its just fine for the odd night out with the family and friends, but my other scope is a iTelescope.NetThanks guys, thank you very much indeed!

This fall brings dead leaves, raking, crisp evenings and more clear skies, and amongst the fall chores I was curious to see how my little home mount stacked up ( no pun intended) against the bigger guns at GRAS.

I therefore performed a very non-randomized high end non-funded pseudoscientific prospective trial to see how my M706 with ST-2000 and Losmandy G11 mount would compare to the iTelescope T11, a 20 inch Planewave CDK with FLI camera in New Mexico.

Obviously, I could not blind myself as to processing the images, because they were certainly very different to begin with, and wearing a blindfold while processing just did not seem to work out very well either. But in the end I was pretty curious to see just what some of the differences were in using iTelescope.Net as compared to my home system, and chose a dimmer than usual image as a stretch for the home equipment. IC 243, a spiral galaxy in Camelopardalis, seemed a reasonable target. It has a respectable size and internal detail with a surface brightness listed as 14.9 with a blue magnitude of 9.1, and is not something that one sees imaged routinely.

The home system has been tracking well after upgrading, and the Intes is a respectable flat field astrograph. With good balancing, alignment and guiding at home, I was able to collect a number of 900 and 600 second subs, and attempted to
use days when we had the best skies, (which at this time of year are "average" at best) and catch the object at a low air mass.
Logging in to T11 can sometime be a challenge, because it is quite a popular scope for science and photographic work. For iTelescope.Net imaging, I decided to use what I felt was best as far as binning and image time, to balance cost of equipment use with outcome. 
Below, you can see the two final images. They are at slightly different scales, but have been approximated as far as position, for easier comparison. Being only a moderately experienced processor, I did not bother to try to balance the color scale or brightness between the separate images, but did attempt to balance them in these sorts of ways as best I could, and used similar techniques to bring out contrast, sharpen, and to control noise.

Intes M706 and SBIG ST-2000 under suburban skies. 600 sec L and 900 sec RGB, Bin 2x2. LRGB 90:60:60:60 minutes. Fair central detail, good overall color, and some nice data in peripheral arms.

iTelescope T11. 600 Second subs, Bin 2x2. LRGB 140:90:90:90 minutes.

No Surprises. The initial things that struck me was the detail in the iTelescope.Net T11 image overall, with nice luminance detail in the low SN data in the periphery of the galaxy, and fairly strong color as well in those low SN areas. There even appears to be a soft arm of one spiral heading off into the lower left corner, almost touching a small galaxy at 7:00.

Processing the detail and sharpening in the higher SN ranges becomes much easier, and in this image, these could actually be toned down somewhat in order to better balance out the overall brightness- the core area is wonderfully bright.

It is interesting how well the human brain adapts to image quality and to colors- every time I look at the lower end resolution image, I am taken by how much I like the detail- unless I again look at the T11 image in comparison. The star colors in the T11 image are also brighter and crisper, despite enhancing this in the Intes image. Obviously, the Intes should have collected more photos to make a more exact comparison as far as image timing, but the overall decrease in noise in further doubling the Intes exposure times would not amount to all that much help. 

Well, iTelescope.Net is better, in this case, of course. If you can keep a secret, I was sort of expecting that to begin with. So why bother doing a comparison?

For me, such an exercise is motivational in attempting to tweak the home system to see if I can get a better image out of it next time.

I see things on my iTelescope.Net images that I want to go back and try to study in more detail with the smaller home system, and also use my home system to help select objects for high end quality images using iTelescope.Net.

It seems to be a nice marriage. And when I am too annoyed with the local weather or too tired to set up a home run, there's usually iTelescope.Net sky that’s clear and ready to use.

Of course, if you don't have a home telescope, you can remove yourself from those related uncertainties in data collection and get right to high end imaging!

iTelescope:  The Answer to the "Imperfect" Storm

By Gordon Mandell. USA


I had been imaging the night sky with my own equipment in a home observatory located north of Pittsburgh, Pennsylvania, USA for about 7 years prior to trying Global-Rent-A-Scope (GRAS, the predecessor of iTelescope).  I had the usual problems, limited clear nights, equipment issues, increasing light pollution in my suburban neighborhood and encroaching treetops obscuring my visible horizon.  The observatory was built on an extension of my backyard deck over the objections of a very understanding spouse and the acceptance of tolerant neighbors. 


It had reached the point where it was difficult to image anything but narrowband targets.  Then I tried iTelescope (then GRAS).  Using the iTelescope systems, I had the potential to image on most nights using equipment superior to my own, under ideal sky conditions, and with the ability to access targets in another hemisphere or those too close to my home horizon .  I have been a member of iTelescope for almost 3 years and have been very happy using the service to supplement my local, home imaging. I guess the reasons I like iTelescope are the same as those of most members; that was until the Fall of 2012.  That was when iTelescope became the answer to the "imperfect" storm.   It all started with a flash of lightning and a crack of thunder.  On that night my home observatory suffered a significant electrical strike.  Although it was probably not a direct hit, it was close enough to damage my Takahashi NJP mount circuit board, declination  encoder and right ascension motor.  And because the mount had recently been discontinued by Takahashi, the parts could not be replaced but had to be shipped to Japan for repairs.


In addition to the damage to the mount, my Starlight Xpress Lodestar guide camera was inoperative and had to go back to Great Britain for repair.  Because of the long estimated repair time required for the mount, I purchased an identical, used NJP mount on Astromart and used my Starlight Xpress SXVF-H9 ccd camera as a guide camera.  If you are ever told that lighting doesn't strike the same place twice; don't you believe it!  Six weeks after the first lightning strike, the observatory was hit again.  The second NJP mount was damaged just as before, as was the SXVF-H9 ccd camera.  This time the observatory computer and a heavy duty surge protector (added after the first lightning strike ) were also ruined.  I had no mount and no idea how long it would be for the repairs to be made.  Then another problem arose.  I was stricken by a cervical disk herniation that left me with intractable pain and arm weakness.  While recuperating I suddenly had an epiphany.  Why deal with all these problems when there is iTelescope?  Over the following months I slowly sold off most of my astronomical equipment including the observatory itself.  Happily, the sales generated enough cash to pay for a badly needed new deck (minus the observatory).  This brought harmony back to my marriage.  
Now I can sit on my new deck, enjoy the view of the trees that used to be a source of frustration, and image using my iPad.
My neck also appreciates not having to move all that heavy equipment around.  Thanks iTelescope, the answer to the "imperfect" storm.
