Bresser 127l Refractor mosaic

Recommended Posts

About 40 degrees last night reasonable seeing. The bresser chinese achro is very focusing critical. I find a slight turn of the focuser can make the difference between a sharp and soft stack. Not easy manually as a lot of shake on a EQ5 but pretty much got close last night i think. Quite pleased with this. Dont forget its only 5 " and mass produced chinese optics. They all show varying degrees of under or over corrected lenses. But this doesnt stop them performing. Infact after getting a certain jupiter image with this scope i was convinced it was a good one. But for one reason or another seemed  hard to coax good lunar performance out of it. likely that critical focussing. And not nailing it. And Filter choice is important with these refractors. I used the Baarder 495nm longpass stacked with a QHY UV IR CUT. Under good seeing it really sharpens up these chinese optics. Put new flocking on the dew sheild. and made a dew shield extension. Helps with that street light i have to capture above. 

Captured at F8 drizzled 1.5 downsized to 70%

Wonderful images!

Thanks Sunshine. i get immense pleasure at making affordable telescopes sing. And this one cost me £170. its nice to have a large refractor. Wouldnt have dreamed of a big refractor like this when i was younger, for these prices. How times have changed. It also shows why these scopes have such a good rep.  Would love a big Tak of course. My missus wouldnt though.

That’s a really good image Neil. You have certainly made the 127 “sing” as you hoped for. Loads of fine detail there. I’m blessed with no street lights yet around here but over the years neighbours seem intent on burning more and more outside lights, often from dusk to dawn. Some of the properties are like Blackpool illuminations !!

Cheers Trevor. still working on it lol. That street light is a thorn in my side. Was happy to get the refractor performing better. Just need to get the process right
