Thank you to all who offered advice. I had not realised that the focus range was so finely controlled. I had been rotating the focus knob half a dozen turns in...

Warp, I would have thought that, too. Maybe he sold out or his partners decided that a change was needed. The note was very clear that Herb was no longer...
Thank you for the advice - weather is bad hereabouts and the job has kept me busy - I will try over the weekend, in the meantime I will check the mechanics and...
Hi I have an ETX70 OTA in my hand at the moment and with the supplied lenses I can get a focus at infinity (stars etc) and a near focus of better than 20 ft...
What are you trying to focus on? For close objects, the distance from the objective (front lens) to the eyepiece has to be increased, so if the object is too...
It's not against the rules, but I prefer that people who want to post advertisements have the courtesy of _asking me first_, _personally_. ;-) Peace, Rod...
Herb York owns Anacortes, which runs Astromart. Some things have changed, but, as I said in my other post, Herb is still very much around. ;-) Peace, Rod...

There is a very long range of focus on these scopes....always focus on something that is clear, such as Jupiter or the moon....a star will focus to the...
Are you using an eyepiece included with the telescope? Do you have a different eyepiece to try? It is possible that your eyepiece may have come apart...

I use two, a 9mm and a 25mm, and is the diagonal prism the 'erecting prism' referred to in the manual - if so no. just the 2 lenses straight into the upright...
I think I saw a posting on Astromart recently, (within the last two weeks or so) that Herb is no longer there Tim ________________________________ From: Warp...
What size eyepiece are you using? Also, are you using the diagonal prism inserted? Dr. Clay _____ Arkansas Sky Observatories MPC H45 - Petit Jean Mountain...
My problem is fairly simple. When I insert the eyepiece into its socket it is impossible to achieve focus using the focus knob. I have to lift the eyepiece a...

Why not list them on Cloudy Nights "Swap and Shop" or Classifieds too? I already know what you think of Astromart so I won't suggest that. "My advice is always...

I'm struck by the juxtaposition of the foregoing posts. A case of the wrong place at the wrong time? Dew behind the corrector plate. OHHH! Water on the moon!...
No, not quite. Moving air will do two things, the first as you say will equalise the air temp. However That only happens when the air flow is very random. In...

The colder it is the LESS water the air can hold. As the fan blows air onto the glass this will produce a slight cooling effect, this effect gets magnified if...
