It has often been said that they are better in scopes slower than F/6. What counts as "horrible" is quite subjective.

I think FLO used to have a statement on its Hyperion page concerning suitability in fast scopes, but I can't see it now.

I apologize if my expression is out of place, and if the topic is that if Hyperions are suitable in fast scopes, i agree, no problem at all. 

Thanx for your comment. Greetings from Barcelona, Spain.

To do a quick star test of the eyepiece, simply pick out a mag 1 or 2 star, bring it to best focus on axis, and move it from the center to the edge, observing any changes to the star's appearance.  Is it still a pinpoint everywhere in the field?  Does it change shape or spread out into a rainbow near the edge?  Does refocusing the star at the edge make it look sharper out there?  It's when you take the time to look for these sorts of changes that you can start to discern good eyepieces from terrific eyepieces.

Thanx, i will do that star test, totally agree. Sometimes the emotion of the first light makes to forget that inicial star test... These days, with the crescent moon, my suburban skies does not show too mucho stars (bortle 7)... Sorry for my english. Greetings from Barcelona, Spain. 

New ep for my dob!!

Last week i received my first Widefield eyepiece: Baader Hyperion 13mm+ 28mm finetuning ring.
The eyepiece is really huge, is a beast!! The weight is 400 gr.
Yesterday i was used it in the moon... The best moon sight ever!!!
The ep is 92.3x in my dobson, and the moon fills all the fov!! Epic image!! Ultra crisp and bright image!!. No turbulences, long time in the fov.
With my Celestron Omni Barlow, the ep goes to 184.6x, with incredible definition. The craters and mountain Chains, the shadows and Every thing is breathtaking. Really impressed with the sights.
Is curious, but in few astronomy forums some people says that hyperion eyepieces are horrible in f6 scopes...
I observed the moon, Júpiter, Saturn, and few more things and the eyepiece works perfect, almost for me...
Tonight we have another observation session, to try the 28mm finetuning ring, who modifies the focal distance from 13mm to 9mm...

After few days with funny clouds and some haze in the night sky, i can try at last my new Barlow. I was little worried about the chromatism that sometimes the barlow lens ad to the views, but i don, t see any chromatism at all. I try it on Jupiter, Saturn, Moon and simply scanning some star fields, and everything looks perfect to my eyes. The 1.5x feature, that is achieved simply threading the optical group of the barlow (the black piece) into the filter thread of the eyepiece converts it into 3 possibilities: In the case of 25mm super plossl, i have 48x (eyepiece alone), 72x (optic part threaded), and 96x (full barlow). I don.t see any image degradation. In my 10mm ep, the full barlow gives 240x,nice on Jupiter and Saturn. The only thing is that the eye relief of the ep is too tight. I need another ep in that magnification with better eye relief and big lenses too look thru. The thread of the 10mm don.t accept the optical group, maybe the thread in the ep has something damaged, i don.t use it never before. Now, i just need to add 2 or 3 ep to my set, to have one low power widefield, and maybe an 8mm,and 6mm for high powers. I know that is not a spectacular first light, but is my first one🙂🙂.

Yes, the phone sensor is most likely not accurate enough to point your telescope, other than just a general direction like so many star charting apps do. The metal of the tube will certainly make things even worse.

But there's nothing wrong with giving it a try. Maybe the alignment is good enough to find an object in your finder scope.  Velcro or a strap around the tube are probably the best ways to attach your phone to the OTA. Good luck!

 

Thank you very much, your explanation is really useful, i will try, and see how accurate that system can be. I post my experience in next days. 

Best regards. Thanx again. 👍🏻🙂

Hi, i just presented myself yesterday in newcomers. I have a skywatcher classic200p dobsonian scope. I have installed on my phone the Skeye app. Skeye has the feature to work in "push to" mode, similar to the Orion Intelliscope system. 

What is the best system to attach my smartphone to the tube? Phone cover+velcro?

I read that the performance can be wrong due to phone magnetic sensors and the metal tube of the scope. 

Some trick? 

Thanx in advance to all. Best regards.

Hi and welcome to SGL. I have the same scope as you and I agree, they are great all round instruments. 

Thank you, i love the simplicity of the dobsonians, in 2 minutes, take the scope out, put the eyepiece on the focuser, and enjoy. 

Best regards.

Cracking kit, Joaquim and welcome to SGL. Looking forward to meeting you on the boards

Thanx Rob, you are really kind🙂. Sure, i begin to post my experiences or question in the boards very soon!! 

Best regards 🖖🏻👍🏻

Hi Joaquim, and welcome back to the Lounge  That's a nice SW Dob you have there, many fruitful hours using it. I fell in love with Barcelona the first time I visited it. How are you able to move around the city with so many tourists visiting your magnificent city.

Steve

Hi Steve, i live near Barcelona, 35km away. I worked in Barcelona city for more than 25 years, is like my second home, but never lived on it. I live in a 20000 population village, more relax here🙂🙂, and better skies!!! Thanx for your welcome!!! Best regards🖖🏻

Mucho gusto!  I love BCN, amazing place. I have been many times, last time was for the Grand Prix..

The telescope you have is in my opinion one of the best, I had one, I loved it, and I miss it a lot! I hope you have lots of happy hours exploring the sky with it

Thank you!! In my opinion, a telescope is one of best things that money can buy🙂🖖🏻. You become a space explorer from your backyard!! 

Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. 

Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. 

Besf regards to everybody
