the $250 truly worth the difference towards the Stellarvue as the scope rings, just insert the proper dovetail for easy stability. Each will need a industry flattener, I could not previous greater than per month with my scope without shopping for 1 - the corners have been just awful ahead of buying the sector flattener. I also experienced to purchase some spacers to get the proper focal distance for my camera. That they had me ship the scope back again at their expenditure. Positive sufficient it absolutely was a difficulty with pinched optics that confirmed up only in chilly weather. They were able to breed the problem that has a freezer check. They replaced the optics, AND sent me interferometer results (something they now do standard using this type of scope but failed to when I bought it).
Early 90s, I feel. Despite the similarity in identify, it was a lot less significant than The existing Skyview Professional. It was an Alright visual mount with the 90mm it arrived with, but hardly.
I see that vtornado has an one hundred twenty mm F/8.3 achromat. I had that very same scope and mount. The tripod was the issue in terms of the scope. It had been just not rigid more than enough. After i mounted the mount on my best tripod, an outdated Houston-Fearless, it reworked the scope, the mount head by itself was high-quality.
2) The improved mechanicals in excess of very similar scopes. An case in point could well be the rings in place of the foot system utilized by many other 80mm triplets.
They had me ship the scope again at their expenditure. Guaranteed plenty of it was a difficulty with pinched optics that showed up only in cold climate. They were capable to reproduce the issue with a freezer exam. They replaced the optics, AND despatched me interferometer final results (some thing they now do conventional with this particular scope but failed to when I bought it).
Judging in the assorted photographs on line, the SkyView Professional mount-head could really very well fit, but I'd personally Get hold of a technician at Orion to create selected.
CNers have requested about a donation box for Cloudy Nights through the years, so listed here you go. Donation will not be necessary by any usually means, so be sure to love your remain.
For an imaging scope, to me a much better focuser is worth it, I had been amazed Orion basics didn't spec a greater one particular However they failed to.
The SkyView Professional will probably be A great deal stiffer compared to older Astroview Together with the extruded aluminum legs but just upgrading the legs with the Astroview is likely to make A serious her response change.
The orion that's like the more mature cel. cg 4 would be the astroview at all over 249. They demonstrate the skyview Along with the 8in f5 reflector on it, inside the clearance web page, not less than they did yesterday, it may be long gone. Common cost is 399 , AND it can be retrofitted with go-way too , but that kit is just a little expensive, JMO
I don't think It can be any a lot better check than the CG4 you at this time have and in fact appears to be being a bit inferior (see this Advert).
I can not attest to their normal focuser, I have not touched just one. I've touched lesser focusers even though and also the aggravation of getting concentration adjust once you attempt to lock it in placement. This doesn't occur Using the Feather Contact.
