If it were in Welsh it would be unpronouncable and unrecognizable in an English translation. -Best, Robert

I like the wider image. It really shows the whole area better.

Alex, I think this is a super result! I don’t find the inclusion of the OIII on the right side distracting or detracting.

Re: Keeping the dust out
I haven't seen a Teflon tape suggesting in this thread actually. Plastic wrap was suggested, but that would add static to an already static heavy environment. Plus, it just isn't a very elegant solution, regardless of how effective it might be. Honestly, I think our wind would make short work of plastic wrap once it got an edge loose. Teflon tape between the CFW clam shells would likely work well, but the gaffer tape is easy, cheap, and adheres well to uneven surfaces. I'm happy with the solution. Thanks for all of the suggestions.

You might try some Teflon tape. No residue and pulled tight no leaks. Isn't that where we started? -Best, Robert

Okay thanks gentlemen. I will be imaging without a barlow in the guidescope.

Re: Guideascope question
It seems to me that your imaging/guiding ratio is perfectly fine without the Barlow. But, if you want to play with the numbers here is a good tool:

Re: Guideascope question
You will be fine without a barlow at those relative image scales it's when you get above 3:1 that it gets dicey, and i would not go above 4:1

Re: Guideascope question

Thanks Brian, I will be using a QHY600M camera. Here are both scope and guidescope potential image scales....
Telescope
0.74 arc seconds per pixel at FL 1050mm
0.97 arc seconds per pixel at FL 798mm (with reducer)
Guidescope
1.98 arc seconds per pixel at FL 250mm
0.88 arc seconds per pixel at FL 563mm (with 2.25 barlow) Steve

It's Guidescope not a Guideascope, damn fat fingers.

Re: Guideascope question
Steve - what is the imagescale on your imaging setup? if you go with the smaller pixel QHY it's possible your image scale on the guidescope may be close enough that it works for you without a barlow. I've seen people use barlows in the past with mixed results

Guideascope question
steven ho
I use the 10x60 Vario-Finder as a guidescope(FL is 250mm) on an AP-140 (FL 1050).
Would it be practical to put a 2X barlow into the "guidescope"?
the camera options available to me are QHY5-III178 and SBIG ST-i, both are mono.
QHY5-III178 = 2.4 µm pixel size and 1/1.8" sensor (USB3)
SBIG ST-i = 7.4 μm pixel size and 4.8 mm x 3.6 mm sensor (USB2)
Thanks for your help!! Steven Hoffman
