nightfisher Posted May 21, 2011 Author Share Posted May 21, 2011 well i have the dual speed focuser on order, that should be here monday and i have come up with a very cunning plan to give the ota a face lift, all items ordered and pictures next weekend, if it goes to plan it will be a bit special!

nightfisher Posted May 21, 2011 Author Share Posted May 21, 2011 The eq5 copes well with it, but good job its not the 150mm evostar as that would be a bit to much Link to comment Share on other sites More sharing options...
spaceboy Posted May 21, 2011 Share Posted May 21, 2011 The eq5 copes well with it, but good job its not the 150mm evostar as that would be a bit to muchI don't think my Evo 120 is all that solid on my EQ5 so I would imagine an Evo 150 would resemble a branch waiting to snap. I have never seen an Evo 150 but I hear they are larger than life. I would really like one but simply don't have the cash to splash on a mount worthy of the Evo 150 Link to comment Share on other sites More sharing options...
F15Rules Posted May 21, 2011 Share Posted May 21, 2011 Nightfisher, that's a great looking scope:), make sure you let us have a first light report?Which crayford are you buying for it? Does it come with all necessary attachments to fit it straight onto the scope? What about the finder, is that fixed to the tube, or will it fit on the new Crayford assembly?I'm interested as I might consider upgrading my Evostar 150 when funds permit..my finder is a Tal 50mm, absolutely superb finder..it fits onto the stock focuser assembly, so I'd either have to drill the tube for a new shoe, or buy a Crayford which has one...I don't think the Moonlite one does? Be good to see the pictures.Ref your new paint job, I'd like to get mine painted white..I just like traditional white on scopes and obviously the Tal finder is white already:p...do you know someone in a paint shop or do you think a garage which does spraying work would take on the job as a one off for cash etc?Regarding the load of the Evostar on the EQ5...I have the CG-5 version and it handles my Evostar fine - for visual. I think the weak link is the tripod. The EQ5 has 1.5" diameter steel legs, the CG-5 has 2"...but mine have been replaced with a solid fixed height timber tripod and it is MUCH more stable than the original legs.I completely accept that an EQ6 would be ideal especially if you do AP, but at a much greater weight (and cost:eek:). So for now I'm happy with the CG-5. One thing's for sure, these big refractors give an awesome bang for your buck:DLook forward to seeing your new pics after the mods are applied:icon_salut:Just adding one of mine, to show the tripod, I know you've seen it before:rolleyes:Dave Link to comment Share on other sites More sharing options...
hunterknox Posted May 21, 2011 Share Posted May 21, 2011 Dave, this should be a direct replacement. Don't know what nightfisher's doing with his focuser but doubtless the end result will be awesome! Link to comment Share on other sites More sharing options...
nightfisher Posted May 22, 2011 Author Share Posted May 22, 2011 I have opted for the skywatcher dual speed crayford as its a direct fit for these scopes.the finder has to be mounted on a shoe drilled and bolted to the OTA (done)i have access to a large paint spray shop and i was going for a white spray on the ota and dew shield, which would work very well, and i would think most place`s like this would do it for a cash price, and not difficult to do at home diyi had a last minute change of mind over the paint finish, wait for the pics!

I hear the larger the objective the more pronounced the halo. I understand that the 150 is more suited to deep sky but I guess it is still superb on the moon. I did find a chromacor for sale but the seller wanted an unrealistic £350 for it and given I could probably get a nice S/H apo for that much I decided not to bother. But a 150 & Chromacor dose sound tempting. I still think the 150/EQ5 is pushing the boundaries but if you say it works it might be worth a try I guess Link to comment Share on other sites More sharing options...
nightfisher Posted May 22, 2011 Author Share Posted May 22, 2011 I have a plan to get a 150mm evostar in the future but only if i can mount it on a pier in an obs hoping in about 18months i might be in a position to build an obs but that involves selling house and relocating Link to comment Share on other sites More sharing options...
spaceboy Posted May 22, 2011 Share Posted May 22, 2011 I won't lie I am very much a reflector man but since getting a refractor I have to admit I do see the appeal. I like the wide views I get from my Evo120 that not even with Naglers can I get from my Newts. I have found with a WELL cooled refractor the CA is not of any real bother so it's not like you need to break the bank with an apochromatic. You and Dave have some nice refractors in your collection and I can't wait to see the revamped ST150 Link to comment Share on other sites More sharing options...
F15Rules Posted May 22, 2011 Share Posted May 22, 2011 Hi guys,Thanks for the links, the SW crayford seems good value at £129?I think the crayford is a worthwhile upgrade..with shorter f l fracs (under F11), it can be fiddly to get tight focus at higher powers. On longer focus fracs the depth of focus means you have a bigger "sweet spot" for snap focus. So the superfine micro focus on the crayford will be good for both Nightfishers and my scopes.I would tend to prefer, like Nightfisher, to mount the finder on the OTA tube, and I always feel nervous if anything is only held if place by one screw, as per the Agena astro solution..Ref the question of CA..yes, it is there, no getting away from it. But at low to medium powers it doesn't bother me as the light gathering of the scope more than makes up for it.I too think a Chromacorr is a great upgrade if you can find one at a good price, but again I've read that the stock focuser and it's inherent image shift can prevent even that piece of kit from giving of it's best.Can't wait to see your new colour scheme, Nightfisher, sounds funky!clear skiesDave Link to comment Share on other sites More sharing options...

nightfisher Posted May 23, 2011 Author Share Posted May 23, 2011 Update, still work in progress but really getting there now, and looking good, the new focuser is silky smooth and fitted like a glove, also this upgrade has added weight to the rear of the scope, helping with the balance:cool: Link to comment Share on other sites More sharing options...
