Hello everyone, I have for some time a prime model 152 with 180mm tube and 200mm lens hood I took measurements with an individual type 1 and it is practically the same tube measured side by side. Now I would like to modify the tube and replace it with a ts individual 152/900 V3. I would need someone...

Galosimo

thanks Mark but I had already posted here my mod of the 150 phase 3

Galosimo

I use 2 single lens, one lens 51mm-300 plus and one lens 51mm+300.
I’am a visualist and don’t take photo

Congratulation

Hello my name is Galelli Simone from Italy and I would like to share with you the new solar project of my new 80mm solar telescope. I started with an 80ED F7 Svbony, 2 collimating lenses F6, external etalon lunt 50mm, 2 thrust bearings, extensions etc. I started with the shares obtained with the hel...

Galosimo

my name is Simone and I'm looking for this baader filter and thank you in Italy

Galosimo

My bf is smaller than the etalon BF = 15mm, etalon 20mm. The doublestuck as I set up with telecentrica works fine.

Galosimo

The important thing is that it works. Experiments serve this.

Galosimo

My is before the telecentric so I collect the beam before, when it is smaller and i just need a BF15

Galosimo

Galosimo

You could change the lens but still the result would not be good because the beam would not reach the correct inclination of the original collimated beam.

Galosimo

Then I repeat I do not use any lens. The original lenses have been removed and 4. in their place use a 5x telecentric made specifically for my focus.

Galosimo

I removed all the lenses from the etalon. You need the telecentric x this system I designed.

Galosimo

New Edit! Then between the two etalon I have a fixed fitting ... well I have now made a threaded fitting with a ring that can block the etalon in a different position. In this way I can take off the reflexes that are formed, not that they give too much annoyance but now the sky beyond the solar edge...

Galosimo

the system has made me beloptik germany and ghost reflections I do not.

Galosimo

I did it to me by a turner on my design

Hello to all. I write after many trials and to describe recent work done to 152/900 and now after having tried for over a year.

Beautiful image. That model is?

I used this a h-alpha filter: http://www.ebay.com/itm/Optical-Interference-Filter-656-3-H-Alpha-0-15nm-Band-Pass-for-Double-Pass-/151670196736 the light fades slightly but the filter must use with t2 tilting. The telecentric system is hidden inside the tube, and this week I build a tilting to erf th...

It is very well known extension

I read your discussion and I wanted to share with you but experience. I apologize but I use the translator. I use a successful hack as previous therad, 152/900 that before I replaced the pst front lens with a -120 for my reach, then still not happy because there was still the sweet spo very visible ...

Galosimo

yes, but then again this is still a beginning then you will see how to optimize. is now under study a system of about f30 / 32 then you will see.

Galosimo

if you mean the part of the sun in h-alpha visible will be about a 15/20 but are still in the experimentation with light beam collimated by about f32, are now about 1.8 degrees and I have to go back at least 1 degree improving lose part of the cone but I do not care because I only have a BF10.

"The problem is that the final beam of telecentric system is 50 mm and the Etalon of PST it is 20 mm ... We were thinking, with Antonello, to try a normal Barlow to get 5X ... with the etalon very close to Barlow."

Galosimo

It will not be at the highest level but your type gets along pretty well

Galosimo

thank you all

Galosimo

I make this review because it might be useful to someone on Changing PST. It all started during one starparty to Bazena in 2013 when I saw in a PST normal and with the clouds, and among other things for a change. After some sacrifices here finally get the PST also in my house http://s20.postimg.org/...

Galosimo

if you can get to the 152/900 so as to have a line with the specific lens. For me it is very interesting this discussion.

Galosimo

I use a lens 25-120

Thanks for everything and I summarize. I or a 152/900 individual mod pst BF10 but BF led to 11 mm with change the front lens 25-120 modified , erf 75 lunt whithin focouser and focuser Secondary SC. Everything works well and turret is that it is a show, very beautiful images from fear to 90/100 x. bu...

Galosimo

but the image will be improved or worsened? I thought of removing only the front lens and the rear riconverge beam, or not?

Galosimo

I was wondering if anyone has done an experiment like this: I would try to work my pst to F30, I mean. removing the front lens of the pst classical 25-200 focal length and mounting a barlow (in my case 5x) telescope 152/900 individual.... adapted to the thread what would come out? I ask this because...

beautiful images but I see that you were in good company!

Hello everyone I'm Simon (italiano)and I'm new to this site, I have a Mod PST Level 3 refractor 152/900 TS not finished yet, but we're almost there
