i use sips coma correction. nice to hear lots of positive views though (pardon the pun)

5mm in my 20" dob. just ordered another to replace it. used to use it a lot on planetary nebs and the planets. gives me 480x. used it in my pm on the moon that was fun960x 😝

hi everyone. ordered last week a pentax xw from flo of course for my 20" dob(no stock yet) so im after a 5mm, i had a xw in 5mm but sold it to raise funds so i know it was a brilliant ep but i keep hearing so much about the delites. ok so i loose 10* afov but will the views be better or should i stick to my order with the pentax? what do you think thanks mike

nice one stu, glad all is good with your dob. just make sure your mirror floats properly and all will be good

large alt bearings allow for big differences in weight at the uta without the dob dipping or raising. small alt bearings need bias to compensate for eps. i can use a bgo of ethos and the tube stays put

when you read my build, didnt you see it 😝 4 years ago and coating is still fine and its used a lot, did use the hammerite special surface primer as well. seriously its ace. well tidy

i didnt use formica for any of my bearig surfaces on my dob build. i used hammerite paint on my ground board and alt bearings. makes the motion lovely and smooth and consistant 😀

that is pants paul 😛

do you mean you wouldnt see them because of your location? just go to a dark site

Thanks chris

elan valley. i made the scope. the buil thread is in my signature 😀

1 more pic as well, mine is the rose wood coloured. With the dob mob

the higher the grade the better. it will take high power better especially when conditions are ace. hence my 20" mirror set from orion optics 😀

as stu says. you know it will be right. as stu said earlier they only need a couple of washers to shim them out. then they are brilliant. very small foot print and very compact and strong

you could drive there, and get them to pre assemble it ?

i found these were very good in my old sct https://www.firstlightoptics.com/ovl-eyepieces/ovl-nirvana-es-uwa-82-ultrawide-eyepieces.html

i made a aluminium disc and put a ptfe washer in between 😛

nice vid, auto colimator is difficult to use. i use the glatter kit 😀

hi dafydd , welcome from me at sgl and from wales. great starter scope, couldn't do better

orion optics uk sell a dob mount kit moonshane converted a 16 ob to collapsing truss design

nice intro... welcome by the way budget would be good. also do you intend on astro photography in the future ?

and mars loves lots of power, as you know john. especially like it did around 5 years ago 😛

hi everyone. nothing special just a few things from tonight with my ace wife scope was set up and cooling by 5, then colimated later on. aligned the nexus on arcturus and polaris using skysafari6 pro(loads better than 5) set out on all the usual targets but seeing/contrast was poor. then after midnight wow, the sky came alive m51 has lovely joining spiral arms lots of definition put the 8e in and the sky took it no problem m101 not quite as good but spiral arms everywere m81/82 not the best but taking 300x no problem makarains chain was brilliant heather had 6 galaxys in the fov using the apm 20 well cool. whale galaxy ,fireworks showing good detail as was m22 havnt seen that for a while. then on to the old favourites m13 , m57 lovely colours m27 😛 then the veil and cresent absolutely amazing, cresent was almost the best i have seen it. god its great to be out, wish i would of gone to my dark site now cheers everyone

i was out last night stu, was looking at markarians chain,m51 the ring 😀 81,82, a few globs but conditions were poor could only just see the joining arms on 51 😛

Just for you
