anither effort.  this time with the 10te.  again a single shot slightly tweaked using ipad photo edit. 

 

the 10te had some yellow green ca so i had to convert to mono.

the 10te with bare objective is good enough to be able to use the manual "fringe" focus assist tool on the olympus camera to focus on craters so i was able to dial in the focus better than the 7te.  i really want a helical precision focuser though to get it perfect.  the focus wheel on the tascos is not precise enough for this.

 

i also tried mounting my q-barlow in front of the adapter and then removing the optics and threading that into the adapter nosepiece.  in both cases i got a really pronounced glare spot near the centre of the image which made it useless.  i also saw no optic improvement over eyepieces.

 

now i think i will get a t-mount spacer kit to see if increasing the back spacing helps.

It makes no sense to use these long, original Barlow lenses. Despite their blackening, they have enormous internal reflections, which completely illuminates the center of the field of view. You will get a much better results using the 0.965 => 1.25' adapter and a modern Barlow lens with a shorter sleeve.

i have a 1.25" visual back installed.

 

i used a baader q-barlow which is a modern recently purchased short barlow.  i am going to work on shoring up the focus tube sag on this scope as perhaps that is the issue.

so i bought a svbony helical focuser and installed it on my 10te in place of my 1.25 visual back and tried some photos of the full moon and saturn last night.  it seems like nice quality but was disappointing to use with the weight of my dslr on it.  i had to use two hands to turn it which introduced a lot of shake to the mount.  it definitely seems like a tool of last resort after you have done all you can with the dial focus.  i also think it should have a protruding  spoke on the focus dial so you can turn it without having to grip the dial.

 

it was way too late to process any pictures but i don't think they were much good.  i have much to learn.  the nearly full moon is much harder to focus on being so bright and no transition zone.  it needs a different approach to camera settings i have not figured out.

First image with my 'new to me' FS-128 (1995 production, so barely a "classic") and my first full narrowband image too.  So this was a quick, rough processing and not a very good PI workflow yet.  Still, it was a lot of fun and very lucky to get several good imaging and viewing nights so soon after getting a "new" scope.

Saturn 08/02/21 thru LX200 EMC Classic 10" with Samsung S21 Ultra cell phone video recording.   Processed with PIPP, Registax, and finally with PS Express.  Eyepiece was either TV 7mm Nagler or 15mm Widefield.  Switched too many times, so I'm not sure.  LoL

 

Seeing was fair to good at times.   I messed with the collimation the other day, unfortunately, and I'm not sure I have it back to dead-on.  Tried to fine tune it, but seeing was too wobbly in the beginning.

gallery_343566_17364_21252.jpg

So, with a real camera, like this, from where does the magnification come? Is the camera essentially an eyepiece?

I know that's a pretty ignorant question, but I really haven't seen one in action.

Added* beautiful image, by the way. Very impressive!

Thanks! The image is projected onto the matrix directly from the lens. So the greater the focal length, the greater the magnification. You can insert a Barlow lens along the way and, for example, double the magnification - but it works provided that the diameter of the objective is large enough to allow for such a greater magnification. I have found that with this telescope it does not work - increasing the magnification by adding a Barlow lens does not seem to increase the amount of detail. 76 mm is not much for photos.
