ED glass in an eyepiece does nothing for eye relief. It is to correct for any spurious color. The same as using an ED objective in a refractor. I have a...
The long drawtube of the focuser I used on the 127mm f/9 refractor vignettes when I use 2 inch eyepieces, so I use only 1.25 inch EPs at this time. I have the...
Here is some information about M31 from Night Sky Info: "M31, the great Andromeda Galaxy, is one of the most famous objects in the entire sky, and the nearest...
Someone named Lloyd posted msg #23819. Do we have any more? I've been looking for the companions to M31. They have been seen in binos, but I've had no luck....
... If my back yard was fenced, this would be an option. However, we back up to an openspace trail. I've had people traipsing thru the yard not to mention Mule...
Weezy, I admit if you said what kind of observing you do I failed to pay attention so if this suggestion is off base, apologies! Back when I lived out west I...
Maroof called me for directions around Asar time. He was near Noor Jehan / Jehangir Tomb. I couldn't help much as I was not familiar with that area. He asked...
8" SCT too heavy. Had one and sold it. The tube on a reflector is still too unwieldy. I have a situation where I have to squeeze between a car and a motorcycle...
The 8 inch f/4 is only 30 inches long and 12 pounds. Mostly you will find f/5 or f/6 in the stores, longer and, yes, unwieldy. The GSO has had great reviews...
8" reflector is too much. I went to a store that carried them. Someone had just bought one and the case for the tube. I asked if I could pick it up and it was...
Actually, David, I took care to get the physical alignment of the cell on the tube perfect by measuring precisely and bolting evenly. The focuser mount is bad,...
Frank Surprised you were even able to get anything approaching decent collimation from from that setup. Keep us posted on the progress with the 6" project. ...
I agree 6" in a refractor is not a good starter scope. My recommendation for a starter scope has always been a 6" f/8 Dob or an 80mm Achromat like the...
An 8 inch refractor would be trouble. An 8 inch SCT is a bulky armload, even for a large person like me. But the 8 inch f/4 Newt? Pick it up with finger and...
I'm using P. Harrington's books. I got really annoyed by the Dob crowd when I first started. I had an LX10 and sold it. It was too heavy and bulky to be...
The differences between the 6" 1200mm FL achro and the 5" 1140 FL are subtle, not at great as that noted between the 127 and the 102 (that probably because of...
Your list is greatly encouraging Lloyd and shows what can be done. I live in Windsor ON Canada with horrible light pollution from our city and Detroit just...
I totally agree. A few years ago, I wanted to see how many objects I could find from my backyard (darkened and protected on all sides by vegetation, my house,...
Hi Pankaj, Welcome to the group. I am not sure if you will find the information you are looking for here on this group but it is worth a shot. You should also...
Dear All, Can anyone help to find a fisheye lens to be mounted on a projector for projection system to be projected on a dome to make a planetarium. thanks ...
... I used Patrick Moore's bino book almost exclusively for my first year of observing, as 95% of the time I used a 4 inch refractor max. and I live in the Los...
First the rant. I know that aperture can rule in urban observing. It is also a fact that the telescope that you can move, carry, whatever is the one that gets...
After deciding that a 6" f/15 Sonotube refractor would be impractical - mostly good for planets, unwieldy to mount and difficult to store, and therefore not...
Unless it is against the rules, I will be posting in the files section a summary description of two OTA's I am putting up for sale. One will be a classic...
