  1. it is my experience so far that "correct only" makes star shapes better but dus not do any sharpening, but that can also just be my misguided perception 😅
  2. You're correct off course, I should have said I that I only check "correct only"
  3. Not had any issues with AI4. I don't use star sharpening i'ts too much and indeed you could end up with artifacts. So sharpening is set to zero en check "correct only" ☑️ These are APSC corners on my RASA 11 V2 Not corrected Corrected
  4. Sunday there were a few clear hours in the evening. I chose to let the RASA 11 capture 1min subs on M31 using the Omegon VeTec 571C. In total I captured 3h55m of data. No filter and no guiding. AstroBin
  5. Good suggestions from Vlaiv. Just like to point out that no filters have been added yet, so the budget of €2000 is a very hard target to aim for. If you swap the HEQ5 for a SW Star Adventurer GTI you would gain some budget back but at the cost of having no more room to grow and being limited to a small wide field refractor. Also, I have no idea how the adventurer GTI is for AP. The HEQ5 is sure bet, no question.
  6. Thanks ! that's a good tip aligning the tilt-plate on the sensor, didn't think of that 😶. Miguel
  7. Little update on the RASA 11. Last week the weather was OK enough to finish tuning the scope and shooting some testshots. This is a 31x30s stack of M31 Worked on tilt for hours using Hocus Focus in NINA looking at the numbers after each run, but in the end I just took looping exposures and tuned it on the fly looking at the stars, this went faster then using Hocus Focus. Iy's not perfect yet, but I think we can agree it's pretty close. And this is a 60x60s stack of NGC281 RGB (Omegon 571C + CLS CCD)
  8. I was planning on 3D printing a dewshield, but it just a little bit to big to print in one piece. I have 2 12kg weights on there. No guider needed —> 10micron mount. Miguel
  9. Some updates: The Baader UFC components arrived today Installed a mini PC and PPBa on the scope (needed to print some new mounting accessories). With a personalized touch Installed the curved ring to minimise star diffraction. With my pier in the lowest position I'm almost touching the ceiling, just checked that because that's my flats position with my Geoptik flat panel, so I'll need to tilt the scope a bit hoping the dew shield is up to the load.
  10. Oh my god, the horror 😱. i have been thinking on a tube for the UFC system too, we’ll see if it’s necessary.
  11. Alan, thanks again for the reply. The protruding element you noticed isn't the clear glas filter, it is al felt covered 3D printers ring to cover up the treads inside the cell, the clear glas filter is already removed. I have done my research a bit and saw that there are possible reflection coming from those treads. the 3D printed ring is just not pushed back all the way in the video, it's flush in normal circumstances. I have ordered the full set UFC pieces, so the 42mm camera adapter (Omegon Cam) , slider base, 2" filter slider, tilter, variable (15-20mm) adjustment ring and 2 x 5mm spacers and the telescope adaptor UFC 70. Just printed a cable router too, but waiting until UFC pieces get here to finish up. It's a fat scope, even on a GM2000 I ran a pointing model yesterday, and I've got to say, Celestron most have done a good job redesigning the mirror support/focusing mechanism on the V2, I've got a very good pointing RMS. The model was comparable to that of my Esprit 120. IMG_6822.HEIC IMG_6825.HEIC
  12. Alan, it is brand new, maybe a design change from Celestron to add some more play in the ring ? Maybe some users had binding problems ? You can see how much play I have in the attached video from my first post. I do have to say when all is well centered it does lock up well and the ring doesn't move anymore. I have the UFC system incoming so I'll see how I do with that adaptor. Maybe a 3D printed shim can help, we'll see.
  13. Thanks Alan, yes I've seen that the knurled retaining ring has a sloped surface to centre the camera adapter. A same slope on the camera adapter would be a better design. But what troubles me more is the amount of play the retaining ring has on the treads of the lens cell. It can actually skip treads when tension builds up and the camera adaptor is not perfectly centre.
  14. Hi, i received my rasa yesterday and i’ve been fiddling with it. one thing that troubles me is the retaining ring on the front lens group. It is a very loose fit and it seems to be very hard to fasten it properly with the camera adaptor. any suggestions ? IMG_6817.mov
  15. Small update, after I bought the mount I had 1 clear night, so I set up for some AP. All went fine and I went to sleep, when I returned in the morning I found the mount dead. Turned out I had a bad sample, that is to say, I had a mount with a faulty main board. I contacted Pegasus and they replied very fast, so I sent the board to Greece the same day and received a new board 6 days later. The new board is fitted in the mount but now I'm waiting on another clear night. Also I did not receive that special nut to connect the adapter plate to the Pegasus carbon tripod. Seems several other people did not receive the nut as well, but Pegasus sent it along with the new board. So Pegasus clearly has some growing pains to attend to with quality control and packing. But at least their service is fast and they are easily reached. You can feel they are good people, ready to help you out if needed.
