I have been enjoying using the Celestron AstroMaster EQ90 over the last couple of weeks, mainly on the developing moon until it got too bright.
But I got seduced by a secondhand bargain, (I hope), in the form of a Skywatcher 130/650 Newtonian on a eq2 mount with an old version of a motordrive.
After decontamination to be allowed into the house, I've cleaned it up and was pretty pleased with the views of the Strawberry moon last night, just using the small opening in the tube cover, I'm still waiting for my moon filter to be delivered.
I can't find much info on the scope.
Can anyone tell me if the primary reflector would be a parabolic and if not does it matter that much.
The primary mirror is pretty dirty, actually had a dead fly stuck on it, I carefully removed the holder and mirror and gently blew the fly off and hopefully some of the dirt with a very low powered airline.
It's still dirty but the views of the moon and some of the stars seemed good to me. How dirty can you let the mirror get and what effect would I see to know I should clean it?
Also the eyepiece holder is threaded on the outside at the 'top', is this for attaching a camera T ring directly to?
Hopefully pictures will attach.
Graceful for any advise.
Hi Looking to add a good quality low mag EP to my collection. Was thinking somewhere 28mm and above, can take 1.25 or 2" and as wide a FoV I can get. Thinking in the Williams, Explore Scientific, Baader, TeleV... range or other good quality without having to sell a kidney to buy...
Like a lot of new amateurs I am completely overwhelmed with the choice of eyepieces.
I have a Sky Watcher 250P Classic on a dob for visual astronomy. I have recently purchased the Hyperion IV 8-24mm zoom (with 2.25 Barlow) as my general roaming around EP. Now potentially looking for a high powered EP with large FoV to get those detailed views of planets and DSOs - the question is which should I buy? I was thinking something in the 2.5-6mm range and happy to go up to say £250 price point for the right EP.
So, what is the wisdom? A 6mm and Barlow, or some where between 2.5 (pushing the scope) and 5mm without Barlow?
