I have Celestron AstroMaster 130 eq. I know how to attach the motor driver, too. I want to dive into astrophotography. But I don't know: How can I accurate polar align my telescope, if it doesn't have any polar scope? I think drift polar-alignment is very hard. Is there any other way? How fast must be the motor driver's speed if I don't have polar-aligned telescope yet? I am buying my new Orion StarShoot G4 Monochrome Deep Space Imaging Camera. Is it good that I attach Orion camera on Celestron telescope? I want to buy ZWO 1.25" LRGB Imaging Filter Set. Is it good to attach ZWO on Orion and Celestron? Is it a good choice to select these machines? And finally: is Celestron AstroMaster 130 eq telescope good enough for astro imaging? (I want to image DSO objects.) Thank you for your effort and time. Clear skies!
At the moment, despite the force10 gale that's blowing (bit of an exaggeration, but not much) the sky is beautifully clear and the moon is riding high in the south-east. And this started me thinking ... Given that sunset is about 8pm here at the moment, if I were to set up the mount and scope at about 6 and point it at the moon and set the speed to 'Lunar', given no polar alignment the moon would probably drift out of the e/p. BUT, if I were to go out again at about 8 and put the moon back into the eyepiece using only the alt-az bolts, would this correctly polar-align the mount? I can't see why it wouldn't - seems to me a bit like the alignmaster routine, only using time-separation instead of spatial-separation. But am I missing something? Also, I am not sure what difference it would make if the moon's passage passed the meridian, causing the mount to flip? OK, it is not the quickest way of getting PA sorted and it could only be done during the part of the month when the moon is in the right place in the sky, but it does have the advantage of happening before it gets dark, so I would lose zero imaging time. And it would be dead-easy using the Telrad. So, what do people think? Would this work? Thanks.
