OK, so I am now convinced that all the hype about the Mallincam is not merely hype. Last night I finally had the opportunity to get from Midway over to the far side of Tallahassee to visit with my astronomy buddy Bob S. Bob had his 20" Starmaster w/ServoCat goto already set up and cooling in the driveway when I arrived just after dark. While Bob lives in the 'burbs, his skies are pretty dark considering that he's not terribly far from downtown Tallahassee.
This was to be a night of trying out the toys that we had been wanting to share, as Bob had never looked through my Ethos, and I had never had a chance to see the Mallincam or the Collins I-3 in action. We were both to be pleasantly surprised.
With the Mallincam Color Hyper (did I get that in the right order?) we went all over the sky. M31, M33, M37, M42/43, Blue Snowball, Eskimo Nebula, Horsehead, Flame Nebula, M1, and some that I am sure that I forgot.
I have to admit that I was skeptical about the Mallincam, however this is one nifty piece of equipment! In M43 I was seeing detail that I never knew existed, though I have seen photos that hinted at some of the detail. The image on the Watec 3.5" screen was nice and sharp, and gave areas of the nebula an almost 3D appearance. Areas of M42 looked like clouds, and you could see real texture everywhere, not to mention the color that was amazing.
In M1, the filamentary detail was as good as any photo I have ever seen, but we were looking at it in real time. This was the way it went on every object we looked at; detail that I have never seen at the eyepiece was right there in your face,in real time, and out in the outdoors actively operating the telescope. This was a fun night!
Now, I guess the argument remains; is this really visual astronomy? Well, yes it is visual astronomy in that you are standing at the telescope, and you are looking at objects in a way that you have never seen them, and you are doing it in real time, rather than processing ccd files that may take an hour and a half. While it does lack the intimacy of peering into an eyepiece, it is an entirely different visual experience. Right now I am still undecided as to whether this piece of equipment will become part of my setup, however, that doesn't take away from the fact that I still consider this to be visual astronomy on a whole different level.
OK, one other thing, and this kind of surprised Bob that I found this more impressive than the Mallincam, but the I-3 thin film eyepiece absolutely ROCKS! Expensive? You bet it's expensive, and not in my current budget, but I can absolutely, positively justify the price. Folks, until you have looked through one of these jewels, don't knock it or the price, as it will blow you away when you look through it. Try the Horsehead with direct vision! Not just a notch in the bright nebula, but the whole head; snout, mane, neck, the whole shebang. M42 in all of its glory, and galaxies that you would never otherwise be able to detect under moderately light polluted skies. You can talk about the green images, but after a bit it all becomes monochromatic. If you ever have a chance to observe with one of these gadgets, do not pass it by.
That's my story, and I'm stickin' to it.

Hello Doug - A few questions.
What increase in aperature does the Mallincam give you?
I have a 5.5" refractor. If you use 14 second integration does that mean my 5.5" might be similar to an 18" dob real time?
What video feed does it use? COuld it be used with a flat panel 15" LCD TV as an example?
Would a barlow be needed to increase image size as my scope has a 980mm FL?
I checked the Mallincam website, but could not find answers to these questions.
Thanks!

Thanks,Walter, it was fun!
Danno, most of your technical questions would probably be best answered by one of the Mallincam owners, and I am hoping that they will chime in here. I was just an observer last night!
As to the apparent aperture increase, it seems to be widely believed that the Mallincam gives at least a tenfold increase in aperture. That would mean that your 5.5" would perform similarly to a 55" telescope! Now, keep in mind that this is speculation on my part, but in conversations with owners of these devices, that seems to be the most common line of thought. I don't know if the apparent increase in aperture is based upon the integration time either. We were using 14 and 28 second integration times, and the difference between the two was noticeable.

Nice report.
1) How important is tracking to the experience? Presumably you might be limited to shorter integration times depending on the object location. But perhaps in practice this is a non-issue.
2) Did you use a paracor while using the camer?

Chris,
I believe that tracking is essential for the Mallincam to work well, regardless of the integration times. I suppose it's worth a try, and I seem to recall that someone had earlier posted that he had successfully used the Mallincam without tracking, but had a platform that was to be delivered soon.
We did not use a Paracorr with the Mallincam last night, and all was fine even at f/4.3.
Trombone,
Focusing is accomplished by watching the first stars that appear on the monitor. Just get the first stars that appear to become sharp. Easy as can be.

Thanks for the report Doug!
Just reinforces my decision - mine should be arriving by Wednesday!
Danno, the camera itself behaves like an 8 mm 50° FOV eyepiece. Therefore, with a 980mm FL, you should have 123X with .41° FOV. You can use focal reducers or barlows as needed. I plan on using mine with a FR on a 10" SCT or straight though with a 90 mm refractor.

Back in September of 2004, I received my first MallinCam - a B&W unit with no cooler and only a 2.1 second exposure limit. I had my 6" Celestron f/8 refractor set up in the yard and I added a Celestron f/6.3 focal reducer to it to change the system to f/5. For a monitor, I was using a Funia 13" TV/VCR combo unit. I live about 40 miles north of New Orleans and my skies are about magnitude 4.5 to 5. My first target was M57. Not only did I see the central star, every galaxy down to magnitude 16.9 was there including illusive IC 1296. I was impressed.
To date, I have been able to go as deep as magnitude 20 with my 17.5" and the 2.1 second B&W MallinCam. For this, I was at New Mexico Skies with 10 percent humidity, 7+ magnitude skies and at 7300' elevation. However, magnitude 20 is the visual limit for the 200" at Mt. Palomar.
So to answer your questions, using a MallinCam will effectively increase your scopes aperture. However, actualy results may vary. I don't know if your 5.5" will "grow" to an 18"; but it will definitely go much deeper than a 5.5".
The camera has two NTSC video output - one BNC composite and the other S-video. Both are active and can be used concurrently. I run the BNC to a 3.5" Water LCD monitor and the S-video to a DVD recorder for saving observing sessions.
You could use a 15" LCD flat panel. I have done so in fact. However, there is a lot of variability in the optical quality of LCD monitors.
The camera has a built in Zoom. OF course, it is a digitlal as opposed to an optical zoom. If you want to increase the power, a Barlow is a good idea.

Thanks,
I just picked up a used colour model - not hyper, but the price seemed good. Then the cloud curse has arrived. (and COLD).
It will be interesting to see if a cooler is needed at -20 to -30.

Trombone, Actually focusing is even easier than Doug mentioned. What I do is focus presented images so that the faintest stars are visible. If you overshoot/undershoot critical focus, the faintest stars will fade from view. That gives you the sharpest focus. Bob Schilling

Jack - Great recap. Sounds like the ticket to share observing sessions as well as adding considerably to aperature without most of the expense and bulk of a dob. Love the idea of sending output to a DVD burner.
Sounds like the Horsehead Nebula might be in reach with the newer Mallicam and TEC140/G11 combo.

After using my MallinCam for a couple of months, I have to agree that this is a revolutionary technology. It puts so much more within real-time easy grasp of a modest scope, than was ever possible before.
It's also a revolution in public outreach. The video output can be enjoyed by a small crowd simultaneously. You can point out aspects of the viewed object, right on the screen, rather than trying to describe it while they look through an eyepiece one at a time.
That said, it does not compete with the expensive CCD imagers for final image quality. But that's not its intended purpose, of course.

Well..I for one don't have the patience or budget or tracking accuracy to spend hours getting a CCD image...there is nothing like the visceral impact of seeing nearly real time views like the attached (with the 7inch AP).

I checked the website, but was unable to find the weight of the Mallincam Color Hyper Plus. Does anyone know what the unit weighs?

Jim,
It is also very compact, very easy size to use. The only drawback might be the various switches are also not big. They are well made however and that is more important.
BTW, the image I showed earlier has some ringing. I note that a lot in Mallincam pix. When viewing on a monitor you see that less, and can make all sorts of adjustments.
Again, the live viewing experience is much better amd more exciting than can be conveyed here or in pix.

One other way to focus is make a Hartman Mask, go to a bright star, turn the gain from 128 to 0 and us the shortest exposer time.
Steve.
One adjustment I found that will help make the background darker is change the gamma setting, from .45 to 1. You may have to up the exposer alittle but it will give a blacker back ground. Nice image by the way lots of detail.

I've followed this thread and others on the Mallincam. Have great interest. All the discussions I can find are on DSO's. Anyone have any images or comments on planetary views?
