    One of the best places in southern Spain is Calar Alto, it's breathtaking, if you have the opportunity to go and weather is good, you won't regret it. I think it's like a 2 hour drive from Motril but its worth it. Really. Another place is el Torcal de Antequera, which is in Málaga, it's also a 2 hour drive but it's in the other direction of Calar Alto, which is in Almería. Also try and visit Sierra de Grazalema, but it's a long drive from Motril (3 and a half hours I think). And while in Granada, check out Sierra Nevada. Amazing too. Best of luck with weather and enjoy, S

    Hey Shaan, A Spanish from the south here! First of all, I'd like to ease your mind and let you know that at least where I live dew isn't something to worry about, what you should be concerned about if imaging during long periods of time is the amount of insects that are there specially now in summer so be careful about that. Also be careful where you're shooting,as I have been told off a few times 🤣. But like you're imaging from a private place that should be fine. If you're anywhere near Andalucía and don't mind driving a bit you can get to some amazing high peaks and trust me, they're really great. Let me know what part you're visiting and if I've been there I can give you a few heads up. And remember to enjoy Spain, it's a great country and people are really kind to tourists (at least where I'm from), and if your stay is like a month or so dont hesitate to contact local astronomy clubs, they're always eager to help and make observing parties (but I dont know if with all the covid situation they'll continue doing that) Cheers and enjoy your trip, S

    Hi, I made the build (as in the planks with the hinge) for the moment, as I dont have much time. But the other day I was thinking that I may have an issue using the arduino stepper motor. Is the torque on this motor enough to lift the plank and the DSLR (a Canon550D) as well as the alt az mount for the cam? Has anybody made a barn door tracker with the normal arduino stepper motor (28BYJ-48)? And if so, any suggestions? Is it necessary to use some gear reduction to "improve" torque? Thanks in advance, S

    Oh sorry, I think I confused happy-kat's design with yours. My bad But thank you both for answering so quickly, I thought it would take days till I got an answer but the SGL community is really cool. I see myself asking a lot of questions in this forum as I am green when it comes to AP. Anyway, thank you very much, Clear skies, S

    Actually I'm building an arduino driven mount, so the rod will move thanks to a stepper motor with a speed of 1rpm (please correct me if I'm wrong). I saw you made a motor driven mount, so I wanted to know how much maximum exposure (like without star trails) did you get with the one you made (the one you posted the link of). Also what focal length would I need to get crisp images of nebulae and galaxies with this barn door tracker. Clear skies, S

    I would also like to ask anyone who has a diy mount if they're actually reliable when using long lenses (about 150mm) and how much exposure time can you get without showing star trails

    That's actually a great idea Steve. I think that I will try making a normal barn door tracker (as in without a bent rod) and get to know it properly before I take on the bent one. Thank you very much, S

    The links you provide are really helpful. I will definitely take some ideas and notes from them. I will post my results here too. Clear skies, S

    Oh is there? Then I'll actually have a look at your profile and find it. I guess ill figure out the varying rpm by trial and error hehe. If I actually manage to do anything I will post it here, if not, I'll just try to do imaging before the tangent problem really arises

    Hey Steve, That's a great mount and it looks cool too. The only problem is bending the rod. Like I found the radius I would need but the problem is bending the rod to that radius. I dont have the equipment necessary and I guess that if I do it with a hammer the threaded part of it would just mess it up. But I can get some ideas from your mount Keep chilling and clear skies S

    Hi, Wait so with a captive nut the problem vanishes? That's really cool. Good idea. And also I'm using an M6 threaded rod with a 1mm/min pitch rate so I figured the distance to be about 228mm. How did you calculate the length needed? Maybe I did a mistake. I guess the main problem I'm having is the way the top plank moves, as i said, i was planning on using a stepper motor to make things more 'precise' but I'm not sure of the step speed I must set it on,I'm guessing 1rpm but not really sure, if you could give some insight on this I would really appreciate it. Also thanks for the fast answer. Clear skies, S

    Hi, As a newbie in AP I recently discovered that astro imaging isn't as simple as I imagined, it's not just "pointing and shooting". The main point is that I need a tracker that will follow the sky's movement. But after seeing the prices at which decent trackers are sold I decided to see if I could build one myself from spare parts at my workshop. Turns out that I can, using two planks of wood a hinge, an arduino, a stepper motor, etc. So I decided to get to it, I have built the connection between both planks of wood with the hinge, but have now discovered a problem. After some investigation, I realized it's quite commonly named the "Tangent Problem" (the rod forms a 90º angle with the bottom plank). So the solutions offered vary from curved rods to involute pieces of plastic and tilting the rod. I also saw another solution that was adjusting the speed at which the rod moves, and since I'm going to be using an arduino-driven stepper motor, I decided that this was the way to go. The problem is that I don't know in what ratio the speed has to increase over time to compensate the "Tangent problem". That's why I decided to pose my question here as I'm sure someone must have done it already. Sorry for my bad english, it isn't my first langnuage. Thanks in advance and clear skies, S
