GSO RC testing review - Page 4

Paul does not have a blue LED in his imaging train..

Apocrisiary - Is that a baffle tube off the GSO RC? or something else? I would have thought a good baffle tube would have a ridged surface on the inside?

That just looks like black anodising, and not flat black painted.
Go to a paint store and grab some black chalk board paint. Better than flat black.

Alex, yes it is off the GSO RC. When you take the CF tube off the baffle tube is accessible and unscrews straight off a centre hub that holds the primary mirror in place.
I agree...as I said in the earlier post it needs that nice fine ridging that eats reflections.
Otherwise flat black paint or that other "fix all" close to everyone's hearts - black flocking paper.
No doubt these improvements will come with ongoing feedback and development of the RC scopes. I have seen a prototype of the new linear focuser that will eliminate the focuser flexure problem. Also the 0.75x reducer/corrector will help with large chips like DSLRs and the new sturdy D-type dovetails will help keep critical alignment in check.
GSO are committed to making an impact in the RC telescope department and I have no doubt they will get there.

hrmmm.. Maybe I'll pull my baffle tube out and paint the inside of it with that chalk board black paint Theo mentioned... Hope it does the trick...

If indeed this can be tested and found to be the casue, i think perhaps it would be best to send the information back to GSO. And At the very least demand a new baffle replacement.

Paul Haese · #67 10-06-2009, 09:43 AM

I have to go with Michael I reckon, the baffle tube is most likely the real culprit. My tube does look a little different though. The inside has little ridges on mine from memory, but it could be shiny, only when I do some further testing (if the weather eventually breaks) will I be able to confirm.

Apocrisiary (Michael) · #68 10-06-2009, 10:40 AM

If it is the baffle tube why are there 3 different rings of different size and brightness?
Maybe the baffle is causing the brightest ring and the 2 fainter reflections are off the Tak reducer/corrector. Does the reflection show up in images taken without the reducer/corrector in the image train?

Paul Haese · #69 10-06-2009, 12:36 PM

There are three very bright stars causing these reflections, that is why there are 3 rings.

Yes the reflections still show up in images without the flattener. TrevorW has had this happen with his images.

hmmm ATS now selling these puppies:

Optical Tube Only $A2150 inc GST
OTA plus Losmandy G8 with Dual Axis quartz drive $4995.00 inc GST
OTA plus Losmandy G8 with Gemini GoTo servo drive $6250.00 inc GST

Well, i could say a total backflip of the arguments put forward by Peter some time back about the cheaper vairaints, but i wont

.

But good on him, as he can provide good experience and technical know how on the RC's in general.

I hope this rush of the cheaper RC's trickle down to the manufacturers of the "Main Stream" mob to lower their prices to a realistic levels.

Theo.

AlexN · #72 19-06-2009, 10:33 PM

Good to see that Peter is offering these GSO RC's quite a bit cheaper than anywhere else... for $4990, the G8 + 8" RC is an awesome deal..

marki · #73 20-06-2009, 12:39 AM

I for one would love to see what Peter could drag out of one of these scopes. Hmmmm I wonder if someone has been doing a little quiet testing whilst the rest of us have been arguing about these scopes

.

Another dealer is all roudn good news for competition, I think that GSO have a good winner on there hands with a little fine tuning. These could be the next revolution post SCT. I would also like to see side by side shootout with a VC200L and VMC200L.

AlexN · #75 20-06-2009, 03:35 PM

Fahim, I might be able to organize that... Next weekend I'll be imaging with a friend who's got a VC200L.. I might try imaging a target for an hour with the RC, then see if I can use my ST10 in his VC200L and shoot an hour on the same target... See how they compare... and at the end of the day, I could easily combine the two data sets to create one 2hr long image... should be good...

Knowing Peter (not very well I do admit), I doubt he'd sell anything that he wasn't satisfied was performing to a high standard. I'd be really glad to have Peter test these babies, cos he'd definitely put them through the works and let us know of any problems.

The Vixen, not the Vixen!!! I just shampooed the dust cap.
How does the sbig connect. 2" I guess? I have a home brew 2" adapter. M42 or M60 thread would be better.

AlexN · #78 21-06-2009, 02:51 AM

Hahha!! Yeah its 2" or a straight T-thread if thats easier..

bert (Brett) · #79 22-06-2009, 06:34 AM

Looking forward to seeing the VC200l vs GSO RC comparison. Let the games begin!

Should be very interesting.

Brett

Paul Haese · #80 23-06-2009, 10:43 AM

No comparison between the vixen and the RC. Every single shot I have seen taken with the Vixen has square stars and the images are not as sharp. Sorry Tyre kickers, but these scopes are superior in many respects. Sure the focusor is a flop but the rest is pure gold. Like it or lump it they are real value for money.

Good to see Peter on board with selling them, that will breed some competition in this market.
