And Just one more to Show my max stacking time(ALT/AZ mode)unguided,,The HH was up very high,near'r zienth,but
this is a 6 min stack in alt/az at that night and altitude was about my limit.You can see
field rotation takin over some...But I take that any time for true simplicity..
of no guiding,alt az auto align...and small scope....hehe
PORTABLE set Up

I put together a you tube of that night,,,But forgot how to upload it in HD,sorry but this is a low res youtube
of that night.....When I figure out Ill redo it for better resolution,,But you can get the idea...

https://www.youtube....h?v=FE5yWIGT4rI


Iv been working on this project for a year now. Obtaining different scope's,reducers, and cameras,and mount to get a
totally easy to use,light to setup,and AUTO ALIGN setup combo,that fun to use...

Im very happy with my results.....and a Hi end refractor at a great price ($750) The total package is under 3k.

Thanks Bob, yes this is with the new model from Revolution Imager. It is an LN-300 11811 PAL that accepts the UTC hand controller  :waytogo:

Here is a M31 pic I took tonight with setup in signature using SharpCap 2.7 stacking.

I let it run 2300 frames (23 minutes) with LN300 set to (X128) 2.5 second exposures. 

Location was in a red/white zone in the city.  The dust lanes looks quite eerie.

Northern California has turned from rain to spring like conditions so took advantage of the clear skies last night.

 

Shot using Lodestar X2 , Lodestar Live, Ha filter, on my 50mm.

Jon, I calculated 1.68 degrees using FOV = chip size/focal length x 57.3 formula. But I don't know how to confirm if that is correct or not. It appears close but I am not exactly sure. I also don't know why the left side of the image is out of focus and has coma but the right side doesn't?

Jon and Joe,

 

The 50mm scope at 162mm FL  would yield an FOV o 2.3 x 1.7 degrees with the Lodestar.  I have the same setup and enjoy it very much.  Good job, Joe.  I suspect your offset coma may be due to the optical train not being square someplace.

 

Don

Don I think I have been cranking down on one thumb screw on the 50mm and not both equally throwing a tilt on the camera. Next time out I will work on getting the camera centered between the two screws and see if that helps. 

 

Thanks

Joe,

 

I think the 50mm has three thumb screws.  Make sure you haven't lost one.  That's a common problem.

Yep, I am missing the third thumb screw?

 

Just looked at a photo and the helical focuser model only shows two thumb screws?

While I was in the area of ngc 3718 I took a few more images of nearby objects.  Here is the first, M 109, stack of two 150 second exposures using a C14 at F2, Mallincam Extreme, IDAS P2 filter.

Why do you stack in progressively 6 seconds? Nice image.

Nick, that is how HDR (High Dynamic Range) imaging works.

The shortest exposure collects the central core at a short integration so the core isn't burnt out, then the next stacked frame is slightly longer to collect more of the object but ignores everything that was in the previous frame, and so on until the longest frame collects the most light in the fainter parts. 

In this way the cores are never burnt out because they are aren't captured after the first 1 or 2 frames, only the out fainter stuff is  :)

 

That's not a technical answer but it explains the process in simple terms  :waytogo:

 

By the way, fantastic result Dwight  :)
