While I was recently in Nevada for NV observing, I took a photo of NGC 6357, the Lobster Nebula in Scorpius, using my 8" Newt with MPCC and 12nm H-a filter, ISO 6400, 1/3 second exposure, averaged for 15s in my iPhone XR using NightCap Camera.  This image has been cropped and compressed to fit here; no other processing.  

 

Here is a link to a NASA post of the Lobster with some great information and a beautiful long-exposure image:  https://apod.nasa.go...d/ap181226.html

 

DISCLAIMER: Taking images is different than the visual use of NV.  It is more akin to EAA because with my phone, I use up to 1 second exposures and automatic electronic photo averaging for results.  With my Fujifilm XT30 camera, I take up to 20 second single exposures.  If you have no interest in these results, please just skip this thread.  Photo results differ from using NV visually, although it is reportedly possible to get this type of image visually, using certain fast telescopes with extreme focal reduction using very narrow band filters.

Nice image Ray. You captured the Klingon D7!

Great stuff Ray!

I can’t get this object from London but did observe it from Tenerife last year with my tv85, nv monoculars and 55mm plossl in afocal mode. Here is my smaller scale image of it from that visit, 30 second exposure with my huawei phone.

I’m returning to Tenerife later in the summer so am looking forward to seeing the lobster again!

Thanks Gavster for posting your image.  It shows how different optics perform on such targets, which I think is helpful to others wondering if their TV 85 would be sufficient with NV... and it IS!  Great image.  You'll probably have your 92mm in Tenerife this year?  Ah, Tenerife... the Canary Islands... how much better could it possibly get?  Your photo also shows the Klingon ship at warp one.

 

Jeff, yes, the Klingon ship is there!  lol.gif   When is your Sky Window going to be operational?  I know, the paint is still drying...

Glad to know I am not the only Trekkie Nerd out there ...

 

On the SkyWindow ... started peeling off the male stencils today. OMG is this a complicated pattern! Major Leagues, while skill set is more like T-Ball. It is called Prym1, Pattern DT. It is supposed to look like this:

Mine came out looking more like a German Panzer. Call it "Afrika Korps". Oh well, Erwin Rommel is one of my favorite historical figures (behind George Patton). 

 

I'll try touching it up with the female stencils. Probably sand it all down and try again in the spring. Keeps me out of the bars.

 

Either way, the platform will be ready at new moon. Too many large Sharpless objects need seeing about now. Isn't NV great?

Ray, I’ll be taking my 95mm Baader with me. It is faster than the Stowaway and also has more infocus so means I can use my 41mm panoptic with the 0.75x rc reducer (this combo doesn’t come to focus with the Stowaway)
