  1. I have to admit that I was a bit put off by a picture I saw of a Cassegrain with an extremely long focuser due to the fact that you need to add multiple extensions like so: On this picture there is almost no more dovetail left ! It looks like it is a nightmare to balance But still, I would love to have the chance to look into one as, like you said, the magnification can be much higher in a Cassegrain and it must kill on planets and the moon
  2. That's what I am afraid of. fortunately I have an SCT focuser on my MAK150 so I will bring it with me when I will meet the vendor to see if it fits... Hopefully it will as it is a 2 hours drive I was also looking at the classical Cassegrain but I don't see a lot of them second hand. I hear they are pretty good and the main advantage is that there is no dewing and it adjust to the temperature quickly since it is an open tube, but how would you compare the view with the Mak180 ? do you see a big improvement ?
  3. I have the opportunity to buy a SkyWatcher Maksutov 180/2700 to replace my gold maksutov 150mm I see that a new SkyWatcher Maksutov 180/2700 has "Skymax" on the tube and the one I am considering buying does not. Does anyone know if there is a difference or is it just a branding name difference depending of the country ? Here is a picture of the Mak I am looking at: I remember seeing somewhere that if I want to replace the visual back with an SCT focuser there was a need to buy an adapter, but the newer Mak did not need that adapter ? Could it be the difference between this one and the skymax below ? Thanks!
  4. Hello ! I did not find you delivery to be problematic. In fact I found the pace, tone and presentation quite enjoyable so I would not worry about this as you will get even better with experience. - I did cringe a little when you said M32 instead of M31 for Andromeda - I know this might seem trivial and I do not want to be brutal but since I will be looking close up at your hands, make sure they are well "manicured" I would guess that you work in some kind of mechanical or manual work and I do not want to shame you (I admire people who know how to use their hands!) but it can be a put off .. sorry to be brutal about this. - be careful with the sound, buying a small mic that you can attach to your shirt is good practice to make easy-to-listen-to videos. I hope I did not offend you by being too honest and I really enjoyed the 3 videos and I think you are providing useful content that will help a lot of people. I hope you keep it up and I will be visiting your channel often. Here is a nice link to start on a small budget and greatly improve you video.
  5. for me it's EKOS on an RPI4. I use Stellarmate. It's a pre-installed and pre-configured image with all the software included, so you just need to put it on an microSD card and you are done. I started with BYEOS but soon wanted to have everything run at the mount so I switched to an RPI and INDI/EKOS to replace all my windows software and ASCOM/EQMOD. I've never looked back since.
  6. You can see a demontration here from the main developper, Jasem
  7. I use the polar alignment routine in Ekos (I run INDI/Ekos) which is a plate solving method like Sharpcap (never used sharpcap so I cannot compare). I cannot stand to have to look through a polar scope on a wet terrain my old knees would not take it anyway ...
  8. Aww thanks for the pictures, I was wondering in term of size what it would look like. I've added a focuser to the MAK and it does make a difference in usability to my taste at least "Cooldown is so much better as well as lack of dewing" is the selling argument
  9. Like they say, going from Windows to Linux is just discovering a new set of problems. I've had my share of problems with Windows, ASCOM and EQMOD, now I have different issues with INDI and Linux; it's not perfect and some will run into "unsolvable" issues with drivers and will have to stop the adventure right there. I was fortunate enough to not run into issues severe enough to make me want to quit. The reason I prefer INDI and EKOS is that I get fast support and reactions from the community. I was bothered by a small detail in the DSLR section and I reported it on the forum, it was fixed the same day. I was also able to participate in a brainstorming session on how to improve the interface and one of my idea was implemented. I like the open source approach to software development. There is another reason that makes me hang on to INDI/EKOS/RPI4 is that it is all the tools are nicely integrated into one interface and you can update the whole setup with just one command. I was tired of having to update every pieces of software on my Windows machine: Stellarium, Windows update, ASCOM, EQMOD, Astrotortilla, sharpcap, hardware drivers, PHD2 and a load of small softwares that I had to chase down on websites to see if everything was up to date. Now I have 2 16GB microSD cards, one that contains a stable image of my whole setup and the other I update regularly. Once in a while I just backup the update and tested image to my other card as a backup that I bring in the field just in case something goes wrong with the card in the PI. Simple and very secure. So there you go, those are not "technical" arguments ( there are some but I do not want to start a windows/linux war ) but I do feel that I got more pros than cons since moving to INDI/EKOS and I do not see any particular pros of going back to Windows. I am not denying that there are crashes and issues with INDI/EKOS but saying that all is rosy with ASCOM/EQMOD/WINDOWS is not fair. It's just that when windows hangs or crash we accept it as being "windows" but we do not show the same amount of patience with things that we are less familiar with Sorry for the long rant ! *running for the door*
  10. After I was given a Mak180 to test for a couple of month, I was going to "upgrade" my Mak150 (which I love by the way) to the 180 but then I came across some reviews on the classical casgrain that made me doubt. Reading your take on it, I wonder how the classical cassgrain perform on planet as well ? I like to have specialised scopes and I was going for the MAK as a planet and moon killer ... now I am not sure.
  11. I belt modded my previous mount (Sirius = HEQ5) because I found the noise when slewing very annoying ... Of course, my main reason was to improve on backlash but it was a nice side effect
  12. I did not know about the pattern in X-Trans array thanks for the info. "The Fujifilm X-Trans is a CMOS sensor developed by Fujifilm and used in its Fujifilm X-series cameras. Unlike most CMOS sensors featuring a conventional Bayer filter array, X-Trans sensors have a unique 6 by 6 pattern of photosites" I would suggest that you try your luck on the PI forum, they might be able to help you pinpoint the issue. Cheers!
  13. It took 20 seconds on my machine from opening to complete debayer (20,247s to be exact) That single frame is looking good by the way ================================================ Reading 1 image(s): C:/Users/ydelisle/Downloads/DSCF2061.RAF Reading metadata: done Camera ...........

  14. Hello, It is not my experience. I do all the processing (post and pre) in PI and debayering never took more than a couple of seconds per subframe. Can you tell us more about the computer you are using ? or provide the subframe to debayer so I can test how long it takes on my computer ?
