This is another finished target for this season.
I (quite) recently bought a TS Photoline 102 ED with FPL53 which performs surprisingly well for a doublet. So I put it to tests and imaging, in parallel with an older FPL51 AstroProfessional 102 ED doublet.
The blue color correction is much better in the newer TS. I shoot luminance often with both and then take the highlights from the better scope.
For this image I also used some older data that I had available, shot with a 130PDS, but that maybe only made my life more difficult. Not that otherwise I shot data through the refractors in a single panel with reducers/correctors, but also in 2 panels with no reducing correctors. Same about the RGB. Some shorter exposures from the backyard, some from a dark site, most of the G data from a dark site, B and R from home (clouds came in at the dark site) and a lot of other adventures.
But in the end I managed to put them all together and made an image out of them.

Almost posting this one out of frustration with the weather but I guess I've been lucky to get enough to make the effort, so here's what I have so far.
Captures between 22 & 30 November through pretty dismal skies.
9x900 Ha Astrodon 5nm
6x900 OIII Astrodon 3nm
6x900 SII Astrodon 5nm
Esprit 150 with the new Flattener/Reducer 0.77x & QSI683
Processed in Pixinsight with a final pass through Topaz DeNoise AI. Still finding it a bit heavy handed & feeding my overcooking tendencies.
Feel free to poke, prod and mumble about it. Be warned, it's not too pretty in deep. I'd love more data but it's been dire. I have 15mins each of RGB for stars but not happy with results so far so desat ones will have to do for now.
Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism.
How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess...
Anyway, here is the video
