    Yeah I normally have ZWO camera selected but it wasn’t near so went for that option. I just wanted to try and get some quick screenshots of the eqmod settings. When you say scope specs is there anything in particular. I can check against when the normal camera is attached. Potentially this evening. 

    I wanted to check that your actual scope settings - focal length,  aperture etc were correct as well as the sensor settings - resolution and pixel pitch - are all correct. 

    I use Astroberry but with an AZ EQ6 GT and it skews and tracks perfectly

  2. Having used Astroberry/KStars/EKOS I cannot imagine paying for a piece of rig control software again. Coupled with the fact it'll run on a Pi3 or Pi4 so no expensive computer equipment to leave out it's just brilliant. Fully built in WiFi hotspot as well so can use portable no dramas at all. 

    When I can find my laptop charger I will give NINA a go too but it will take a lot for me to move back to a laptop/full fat PC.

  3. My occasional series of possibly stupid questions is in danger on not becoming occasional but hey ho - I'd rather ask than have it right in my head and be wrong :).

    So, I have a 2x barlow.  If I plop that in my 105/650 which is c. f6.2 does it, to all intents and purposes, just become a 105/1300 f13 when putting details into various software packages to work out FoV etc?  In my head this is what it should be but as I say I would rather check.

     

  4. @tooth_dr I keep looking at 3D printers thinking 'I really want one of those but can I really justify one'. And then people post some really handy looking stuff they've created and I edge a little closer to getting one :)

    I want to make an adapter to mount my Bahtinov mask that i got for my 105mm frac onto my Sony RX10 and a 3d printer would make that a doddle too...

  5. What will be my chosen site is about 40 mins drive.  I could find darker skies closer to home but this will be a private, gated field with parking right by where I will want to set up and it has pretty much unrestricted 360 views of the sky too so all in a decent spot...

    I have been using my Sigma 50-100 mm F/1.8 zoom for wide-field imaging, and whilst it works well enough on comets, using my Canon EOS 80D, the smaller pixels and longer exposure times I use for DSO imaging with the ASI183MM-Pro show up deficiencies. As I have a Canon 100 mm F/2.8 macro, I would like to use that instead. It doesn't have the tripod attachment, so I have cobbled together this

    using a pair of guide-scope rings. Now all I need are clear skies. I will be giving up a whole f-stop (and a bit), but hopefully the image quality will be better. Or perhaps I should get that Samyang 135 mm F/2.

    I have been thinking of trying something like this.  Am I right in assuming you have bought an EOS Lens to M42 adaptor to get the lens mounted?  I am keen to give this a try...

  7. I was out for an hour and a half or so testing whether I could get my Sony RX10 to be fully controlled (bar focussing) by KStars/EKOS.  Got as far as getting it to plate solve and successfully saw M81 and M82 on-screen before a couple of random technical issues killed the connection to Astroberry from my workstation.  My the time I had got them resolved the clouds had rolled in.  Still, an interest bit of experimentation - I am really interested to know what data I can pull in using it :)

     

  8. Well proof of concept has been tested and it works - managed to set up a routine, plate solve M81 and start imaging however the clouds then came in.  Also I need to work on focus a bit - nearly there but was visual and handheld so was very tricky.  Need to make an adapter to fit my Bahtinov mask onto the camera.  Shouldn't be took hard :)

    Trouble is clear nights are not in abundance and want to do some 'proper' imaging as well so will have to fit this playing around in somewhere...

    Thanks Olly. I don't use Pixinsight or PS, but I'm just out of the trial period for APP and am just checking out the features in Affinity Photo v1.9. My only experience is with OSC, so with RGBLHa I'm rather stumbling in the dark :smile:. But then that's what learning is all about!

    *Puts on sinister but inviting voice and whispers* Try PixInsight.  Go one - you know you want to *end voice effects*.

    Genuinely though, makes processing LRGB images at least very straightforward.  Particularly in situations like this where you have the subs all pre-processed and stacked etc.

    Thank you very much @dannybgoode

    It seems plate solving is going to be the solution. Investing in a small, light and cheap guiding solution, that would be even more expensive than my ASI224, is something I might consider in the mid term. Maybe along with a mount and scope upgrade and a DSO camera. Will $€€.

    Meanwhile, I've read about plate solving but people mainly focus on mini-pc + linux. Any Windows based (offline if possible) software? You mentioned APT and KStars+EKOS. Would work for me?

    Thanks again

    Windows - APT works well and there is a fully featured free version although the licensed version is very cheap.  I cannot remember exactly how to get plate solving working however there are some excellent YouTube videos on the subject.  You can get it working fully offline too.

    KStars/EKOS is predominantly a Linux based solution and with Astroberry will run on a Raspberry Pi so great for portable work but it is also an excellent control package in its own right and is what I use.  Again it will run offline but having a data connection is useful.

  11. Well, it is interesting if like me, just for fun and just to post pictures on various Sony RX10 Facebook groups that are not humming birds, eagles and insects; to discover that EKOS recognises the Sony RX10M4 as a Sony DSLR and will control it accordingly.  I had been struggling to find something that would talk to the camera and I could not even get EKOS to work and then I realised I had the camera in 'Control with Phone' mode which knocks out the USB port for control by PC and only allows it to work in mass storage mode.

    This setting changed and bam - all seems to be working properly and it even pulls down Sony RAW files into the image preview.  Now, I am not saying the sensor will be any good or up to the job of much but it will certainly be fun to play with, particularly for larger DSO's.  I can only fit the core of M31 in my proper imaging setup for example so this will be fun to try out :).  That said the RX10 is a massively capable camera so I may get something at least half reasonable out of it and it will make a change from BiF :D 

    Photo is KStars/EKOS and the image in the bottom left of the sim racing wheel is evidence it works!

  12. @barbulo - in that case plate solving is the answer.  No need for a guidescope etc and you can do it all with your current kit.  With a narrow FOV a visually aligned PA, even carefully tweaked, and then relying on the mount's goto routine is unlikely to be accurate all the time, certainly not accurate enough to properly frame DSO's.  Plate solving on the other had is accurate to a handful of arc seconds - I have mine set to resolve to an accuracy of 4" which it does every time without fail.  I could got even further if I really wanted but I don't see the need.  I may test it down to 2" though just for fun (the 4 and the 2 being arc seconds - 4" is 1/18 the distance between Polaris and its companion star).

    My routine is as follows - visually align Polaris in the polar scope, focus, plate solve target, image.  As per my earlier posts you just need a cable to link your mount to the computer.  Also re: guiding - a small guidescope and camera do not weigh much and I doubt will tip you over the payload threshold.  With an EQ3 mount you're going to struggle to get long unguided subs anyway but at least using plate solving you will very quickly and easily be bang on target every time.

    So after all, I'm answering kinda late, but I found a 150p for 260 from Finland, so I ordered it, for people who are interested I'll post a follow up once I recieve it, about my expirience, thanks for tips tho!

    The 150P is a great scope imo and often overlooked. Much more light gathering than a 130 whilst staying a very sensible size, unlike the 200 which is starting to get a bit cumbersome - especially to beginners. 

    I've got many of my astronomy firsts with my 150P, it's never going to be sold :)
