    That's a great first shot.   Keep going!

     

    OK, besides the "keep on with what you're doing".     Here goes

    You didn't tell us what camera settings you used.   Was it automatic or manual?

    If manual, I'd shorten the exposure a stop or two.  That'll sort out the blown out limb.

    Next, take lots of shots.   I mean 100s.  Then run them through stacking software and you'll find that you should end up with a sharper image.

    For the moon and planets, what people tend to do it make a movie with the highest FPS that you can get (shortens the time needed to make the film)  normally about 2000 frames. So it's only a few mins, then run that through a program like Registax.

    This will have a couple of effects.... 1. lots of frames captured quickly.    2. saves your DSLR frame count

     

    Thanks for the advice ( I’ve only just seen your post ) the camera was on manual focus , and was a single shot . .. apart from that I really couldn’t tell you what the other settings were . I’m really keen to start taking photos with my other scope as the dob isn’t really designed for it . Half the “fun” is learning how to do stuff like this . And the rewards are amazing .

    Given you have both the dob and the refractor which have you been picking up to go outside and observ with. A light bucket or not if it is left inside it is a dust bucket.

    Though an altaz tripod swap for the eq5 would be super fast to set up. How big is that cupboard...

    I have to say , I have used them in equal measure ... I tend to take out the dob first letting it cool , whilst I set up the EQ mount.. which actually does grate on me sometimes ... but once it’s set up I love using that little refractor .. I’ve also got a go to set up on a tripod and I sometimes put the refractor on that , if I’m feeling a bit lazy that is ... I really love finding stuff for myself . So , at the moment I feel I have a great set up ... I suppose , if I’m honest a large 280mm Cassegrain would be the ultimate answer for me .. just one scope , one mount , that ticks all boxes ... hmmm , now there’s an idea

    Sounds plenty good enough for visual. I quite frequently pan around anyway using the slew controls anyway so perfect alignment does matter so much. Imaging is a very different matter obviously. Getting the balance right should help too.

    Yes , I do intend to do some photography so I need to get it spot on . But , earlier on it was great not having to move the scope around whilst I was using it for visual

  4. A quick update . Tonight the mount is tracking well ... not perfectly though ... I have to say the balance isn’t 100% , but I did polar align and level the scope .. I had it tracking mars and a few stars and it held them in view for about 30 minutes or so ... I know this isn’t quite right but I will look at the gears later when I bring the scope in . I’m sure that I’m on the right track now ( pun intended )

    Does it not set the manual slewing speed when you press the Up/Down/Left/Right buttons Peter? That's how my Vixen DD-3 controller works, you have a choice of slewing speed.

    I don’t want to sound like I know what I’m talking about but the higher speeds does indeed have a bearing on slewing the scope .

    The gears look too loosely meshed to me, there will be loads of backlash. I would adjust them so they are closer, touching but not binding.

    Ok .. I will re align them, thanks  .. can I ask , if the Dec doesn’t move whilst tracking is there any purpose having power to that motor ? And , looking at the handset controller I am presuming that tracking stars requires the slowest speed , I.e the 0.5 setting .

    When you are tracking you have already set the correct declination but the object you are tracking is moving left to right not up and down so Declination is not required

    Lol , now I feel even worse because it’s so obvious .. thanks Sland and everyone else .. it just goes to show that people shouldn’t be afraid to ask anything .

    The motor at the top is the DEC drive. It should NOT move when tracking. Only the lower ( RA ) motor should move when tracking.

    The power leads must be the wrong way round.

    Well , you are absolutely right ... contrary to the instructions .. it’s crazy how they printed this wrong . I’ve just swapped the leads and , hey presto ! The RA is now moving and the Dec is now still ... I hope that this solves my problem... Geoff also said about the leads , so thank you guys . Tell me why the dec doesn’t move please whilst tracking (sorry if I’m appearing as an idiot but unless you ask you will never know ) 

  9. Why does the motor at the top of the mount  visibly move whilst the other motor doesn’t seem to move at all ( unless I press the buttons on the handset controller ? I’m sorry if this is an obvious question to you guys ... I know the motors are working because I can hear them .

    How quickly did they drift out of view?

    Why don’t you post up a picture of the controller? Did you check the things I suggested, mainly that the correct hemisphere is selected ie N.

    Geoff’s suggestion of the plugs being the wrong way round is another good one to check.

    Hi Stu , I’m checking whether the motors are actually moving ... I’ve taken a photo of the controller .. including the inv dec and inv ra .. not sure if they are in the right positions AE9A16D6-AC18-43D3-BA1E-8C4D9F2C5F66.thumb.jpeg.46f7d82a4818767687bccd47a1d8ed9e.jpegy

  11. Hi Stu ... yes , good idea about the picture ...will include one tonight .. i checked the leads , when i swapped them the motors stopped working all together ! I've definitely got the Northern Hemisphere setting on ... i think it must be down to incorrect polar alignment ... and incorrect levelling of the scope . These motors have three speeds 16 , 2 & 0.5 ... And three settings , sun , moon , and stars .. i assume i should be using the settings , Stars and 0.5 (maybe i'm wrong here) By the way , the star drifted out of view within 10 minutes

    I keep my 8" Dob in the back corner of the entry coat closet.  Other than taking up some shoe/boot space at the bottom, it's hardly noticeable once the coats are pulled in front of it.

    I keep my 15" Dob at the back of the deep closet under the stairs.  Since that space has little headroom, it's not missed all that much.  The fracs, Mak, and eyepieces sit on and around it.  They don't impact the space at the front of the closet for coats and shoes/boots.

    A quick update , the dob is still with me ,although I’m reminded constantly that I’ve three scopes and only two eyes !!! I too have found a space under the stairs but currently it’s taken up with my eq5 ! What I have found is that the dob is a wonderful scope that is “up and running “ within 5-10 mins whereas my small refractors take considerably longer ( due to setting up the mounts etc) . I know the above may seem obvious but , let’s face it , the main reason we like astronomy is to see things that are normally too small or too far away to see (again , obvious). And although the refractor is small , take anywhere ... the  dob is my fav scope . There rests the case for the defence for keeping all my stuff !

  13. Hi , I’ve just purchased the dual motor system , to use with my EQ5 .. i tried them out last night but when I returned to the scope , the target had disappeared from view . I know both motors are working because I can press the handset directional buttons and the cogs can be seen rotating . I know I need to polar align the scope , something I didn’t do ! Can anyone think of anything I’m not doing or should be doing ? Sorry this is a bit vague , but maybe someone can just shout the word “idiot” at me and offer some advice , as , let’s face it there are precious few instructions in the box . Thanks in advance .

  14. Ive just bought the 2 motor kit ... although i stupidly forgot the batteries , so , hopefully tonight i will see it all in action .

    For me its the perfect solution , for the EQ5 . 

    Astronomy can be a very expensive hobby , as im finding out ( 3 scopes , and a host of accessories such as field flatteners etc) , but its a hobby that never goes out of date and lets face it the equipment will last forever if looked after . 

    Maybe you can wait a while to save up the extra money for the "goto" .. and then , at that point you will have a choice that doesn't involve the money side .

  15. Hi Guys, sorry , i wasn't ignoring you . i was away this weekend ..fortunately it was raining at home ( thats how astronomy gets you .. you actually celebrate when you don't miss any clear nights lol) .. Great Pic with the phone Dave . Very interesting about your grandfathr too .  Im giving my z73 its first light tonight ...if... i can fix the new tracking motors on my eq5 .

    And , i would say , Swoop ... i really am so happy that i rediscovered my enthusiasm for this hobby .. and this time im getting into photography as well . a real plus .

    +1 for that; and, moreover, the negotiation problems too, I hope. More advantages: fast thermal equilibration of the mirror, easy take out - stow away procedures, both allowing for more observing time. And - anything is at hand.

    I'd try to keep the scope. The step back from 10" to 4" isn't easy at all, as you are already "spoiled" by the views the 10" gives. The fracs are an excellent complement, but no substitute, IMO.

    TBH Stephen i really am getting into the photography side of astronomy although i know very little about it at present and thats why i bought my z73 . But i love the Dob for the very reasons you outline , ie the quick set up and go, and of course the great views . I want to keep it , got to convince my lovely wife .. taking her out for a meal tonight , its a good start :)

    Hi Louis ..its like a jigsaw puzzle for me , the Dob sits in the living room , watching tv with me and the wife !! , the 102mm refractor is neatly stored in a cupboard with its goto mount , and the z73 and the eq5 (in bits ) lay under the stairs ...the Dob is the prob , on show in the room , although i think it looks great , the wife doesn't share my view.

    Tell me about it - four years in, spent a packet, still have a long "wants" list!

     

    DO try and keep the Dob - it complements the frac nicely and increases your range of viewing pleasure. 

    Negotiations - try offering your wife something for the house.  Good luck!

    Doug.

    Doug i'm going to submit your words as evidence , i will let you know how i get on lol
