Hello all, I am planing to build wheelbarrow for my 17,5" Truss. After searching about one hour in the archived posts, I couldn't get what I need. So I am just...
Wow Theo, you sort the issues out with your TD. This is great news. I am really happy for you. How does it performs? Now i can say: Bonne merde!! (at last!!)...
I shouldn't have waited a week to respond. However, look for the book "The Dobsonian Telescope" by David Kriege & Richard Berry (Willmann-Bell, 1997), p....
Let me first edit my previous post: I heard a lot about this book. And yes, you are probably right, "The Dobsonian Telescope" by David Kriege & Richard Berry...
unfortunately, I can't find it overhere in Holland Anyone who wants to sell his book to me: The Dobsonian Telescope" by David Kriege & Richard Berry? Or if one...
Johan, The handles that Discovery sent for my 17.5" TD where not made from wheel barrow handles but from post hole digger handles. The difference is that wheel...
Hi I have a 17.5" f/5 order with Discovery. Do you think I will require a Paracorr for a 17.5" f/5? I'm primarily going to observe Deep Sky Objects. Regards ...
Hello Akarsh, I have the 17.5 F5 Split tube and from my experience I start to see the curvature of the primary mirror with eyepieces at 21mm. So depending on...
edited@2020 Akarsh, You probably won't need one. Coma will not be noticable. I had the lightbridge 12" f5 and never noticed coma. I have the paracorr for my...
Hello Thanks a lot for the inputs on the Paracorr. I don't think I'll buy one, atleast for the present. Johan, thanks a lot for the good news. I wanted to make...
... Akarsh, I would like to make a few points about your choice of the Panoptic 41. I did see that it is over 100 dollars cheaper than the 31 Nagler so if...
Hello Chris, That was a very well explained argument. Yes, as you expected, it was the price that made me choose the 41mm Panoptic over the 31mm Nagler. In...
Hello I'm primarily a DSO enthusiast and the sole motivation for me to make a huge jump in aperture from a hand-made mildly astigmatic 8" f/8 to placing a...
I'd say a 22-26mm wide field would be my choice. A 26mm Nagler would yield nearly a 1 degree field of view at 85X. That's a very nice general purpose DSO...
... I have the same scope as you will have and use all naglers. -I spend most of my time with a Type 6 13mm. Perfect for the closer globulars, most galaxies...
Hello Jerel / Chris Thanks for those inputs. I think I will be viewing with a 11mm, which will give me about 200x. As Chris pointed out, I'll probably be ...
Akarsh, I'm using the Meade 4000 QX Series 5 element, fully-multi-coated, and a FOV 70 degrees. I would buy a couple of these eyepieces and a good 2X barlow....
Is it just the AFOV, or is there more ... more ... Akarsh, Plossl, is a generic term for a type of eyepiece. This type usually has 4 lens elements and an...
That depends on the Plossl. Given a high quality Plossl (like a Televue) I understand there isn't too much difference other than FOV. Do you have a tracking...
Hello, ... Thanks for the inputs. I think I'll manage with a Televue Plo"ssl. I don't have tracking, but I guess I'll put up with the drift and get used to it....
A Meade 4000 series isn't a plossl. I'm sure the Televue a Plossls are way better than Celestron, Meade, Orion and etc, but I like the FOV of 4000 series. If...
... Just a thought. You could spend your money on either a panoptic 24mm (.7 degrees in your scope) or a 16mm type 5 nagler (.57 degrees in your scope) and a...
Sorry to confuse the issue, (but really it's the retailers who have confused the issue), but these oculars are not the same over time. For example, that Meade...
