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

Ok, another clear night allowing me to finish up another target, the cone nebula. 

https://www.astrobin.com/qheae1/

I’m overall happy with it, but there is one thing bugging me and that’s the OIII blob on the right side of the frame.  When showing it to the wife and kid, they find it to be a distraction from the rest of the image as it pops out compared with the more ethereal pastel coloring of the rest of the image.  On the other hand, I’m not finding many Cone Nebula image that include it, making it more unique.  On the third hand, perhaps people don’t include it for a reason?  Here's a cropped version as well.  Any opinions one way or another?

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

Eric Weiner
 

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

For those interested, electrical tape around the CFW spacers and around the two halves of the CFW seems to be working.  At least under typical Front Range wind conditions.  I've got some gaffers tape on order to replace the electrical tape to avoid adhesive residue sticking to parts.

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

Re: Guideascope question

Eric Weiner
 

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

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

LOL


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

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)
