      Hi, Folks
       I am only a few weeks into astronomy and started off with a Celestron 9.25" Evo on the standard AZ mount. I guess with hindsight this wasn't the best place to start and also with hindsight I would have done better to have bought a GEM mount. Anyway, lesson learned and at 71 years old I have to speed up the learning process compared to younger enthusiasts  I have 2 issues. 1/ Its a pain dragging the scope out into the garden and setting it up every time I think the fickled weather might be obliging. 2/ I now know that the mount I have is useless for long exposures and a wedge is fiddly to get polar aligned.
      My question is, though I gather wedges are a PITA to setup etc is if I was to build or buy a pier for the backyard and use my existing mount + a wedge is this a reasonable way to go? Though it's fiddly to set the thing up once set I could leave the mount, wedge, etc covered up and would just need to drop the OTA on when I wanted to use it.  Is this reasonable or am I missing something fundamental down near the bottom end of my learning curve
      Any advice much appreciated and don't feel you have to spare my feelings

      Hi,
      I currently have a Lunt 50THa and I am looking for something showing more detail and contrast on the sun's surface. I have been considering the new Meade SolarMax III 70 Double Stack, the Lunt 60 with DS (fairly expensive in comparison) and now stumbled across the Daystar Chromosphere. My key considerations:
      - I love that I can just take out the Lunt at lunch time, put it on a photographic tripod, and I am up and running in about 5min. 
      - When travelling, it would be easier to have one telescope to take with me for day and night use
      - Cost is certainly an aspect - I do not want to spend more than about 3000 pounds.
      May I get your input on a couple of assumptions I am making (and which may be completely wrong - sorry, I am not a telescope expert, I just love using them...)
      - The only purpose of double stacking is to get a narrower bandwidth using (cheaper) filters with a wider bandwidth - by using two 0.7nm filters tuned to slightly different bandwidth the Lunt and the Coronado achieve 0.5nm effective transmission.
      - A Daystar Chromosphere with a transmission of <= 0.5nm will hence show me the same detail as a Lunt or Coronado Double Stack with a single Etalon
      - A refractor up to 80mm does not require an additional ERF
      - A relatively cheap achromat will do - as I am only observing at a single wavelength, the correction for multiple wavelengths really does not make a difference (at least for H alpha)
      So on that background I guess an 80mm refractor with the DayStar will give me a really good solution  am I right?
      Best

      Hello stargazers! I am a 14.5 year old boy currently exploring the hobby of astronomy!
      My first Telescope is the Celestron Firstscope!
      This post is going to contain mostly everything i do from now on!
      i will  occasionally post some tips  and tricks as well as some  images(rarely)
      I am soon getting a 8" dob , but that doesnt mean i wont be using the Celestron firstscope.
      Hopefully, one day i can look back to this and remember the beggining of my journey as i am intrested in studying astrophysics/ astronomy in university . And if not, i will continue exploring this hobby.
      So Lets start!
      Astro Journal #0
      So this is almost everything i ve done so far, i have had the telescope for almost 3 weeks now and have used it quite oftenly.
      The first time i used it was  in relatively okay skies,i had no idea what focusing was and just looked at unfocused stars for that day.I cant believe i had such ignorance! After i tried finding why the stars were like that, i finally unsterstood the purpose of the focuser! The next day i used it on the cresent Moon, it took me 10 minutes to find with the 20MM eyepiece supplied with the telescope XD. ( even though it was righ infront of me)
      It was quite nice! I was able to see some craters on it and focusing was pretty good. Then i turned to the 4mm eyepiece.(75x) mag
      it almost covered the entire fov. For some reason the 4mm eyepiece isnt able to focus very well in general. And it was kind of blurry , but still enjoyable!
      Here are some pictures i took with it:
       

      i continued viewing the moon for a couple
      of days, then i decided to do some nebula viewing.
      I was despirately trying to find orion,as the orion nebula was and Is my FAVOURITE Nebula, it took me some time to realise that what i thought was pegasus was actually orion 's belt and sword  ?‍♂️. 
      The night i first observed orion was a full moon night. It took me around 3 minutes to find the orion nebula in the scope. I just happened to notice it because of accidental adverted vision.
      I ve heard of adverted vision , but hadnt had the chance to use it , until then. I had reasonably high expectations for a 3" reflector, and wasnt sure if i was looking at it or not. It looked like a faint colourless fuzzy blob.
      After reporting what i saw to the forum they assured me that i had indeed saw the orion nebula.( this all from quite light polluted skies!)
      Even though i had high expectations i was pretty satisfied with my views.
      3 days after, the moon wasnt very visible so i  went out to observe. What i saw amazed me. It was considerably brigher than before ,using adverted vision.
      The idea of looking at the nebula itself in combination with the even better view, astounded me.(in the same skies)
      I loved it!!!!!!!!!!! After some though i was very suprised that such a cheap instrument(got it for 60euros , but you can usually get it for around 50) can show you that much!
      Yesterday i woke up to see the moon venus and jupiter( I wasnt  able to view the jupiter-venus conjuction  because of clouds, same with the Super Blood Moon.  Guess i gotta wait another 19 years ?). I was able to find venus before i left for school. it was okay with the 20mm eyepiece. I just didnt have the time to view it in the 4mm( i know the timing was very unfortunate , didnt want to miss the buss)
       
      Astro Journal #1
      So here we are! Today!
      I used the telescope in my backyard(they skies are okay! i can make out around 50 stars in my fov (around 180 degrees)
      I took a view of the orion nebula! You know what they say! You ll never see less than you saw yesterday!(except if the seeing conditions are worse ?)
      I was able to see quite more using adverted vision than the first time!
      { For those who dont know, adverted vision is when you dont look  directly at the object you are observing ,as the areas in your eyes that focus on something arent as light sensitive as the areas who do not.  So this way you achieve better brightness and clarity }
      Then i took a look at Taurus! i noticed some stars and then headed right for The Pleiades!
      The Pleiades , filled the entire Fov of my telescope . It had a pretty clear view. I did not however notice any colour or blue tint surrounding the stars.
      I wasnt expecting much to begin with so that was okay!
      I took some pictures of the Orion nebula! 
      This pictures indicate what you will see with bad seeing full moon  some light pollution and no adverted vision.
       

      However, the results with clear skies, adverted vision and no moon will be WAY better , i Promise. Dark skies will help you the  most when looking at Deep Sky Objects 
      Also FOR BETTER VIEWS Dont forget to DARK ADDAPT: DARK ADDAPTATION ALLOWS THE EYE TO SEE MUCH FAINTER LIGHT . TO ACHIEVE DARK ADDAPTATION TRY AND SPENDING AROUND 30-40 MINUTES IN DARKNESS ( AND NO CLOSING YOUR EYES FOR 40 MINUTES WONT WORK) And be careful. Even a look at your cell phone will take the dark addaptation effect away. So if you want to see somehow, use red flash torches,as red is the lowest wavelenght in power. 
       
      The views you will get on the orion nebula will be amazing! 
      Guranteed!

      Hello ,
      I am physics student in Turkey . I have used telescopes but they were manual mount because  of that  I do not have any experiences with GO TO  mounts . I upload photos  and I pressed alignment button before finding 3 or 2 stars .  Still  ı did not  find any stars from  catalog  . I really watched many  videos but I did not do it well  my  process  still not  continue . 12 photos  I upload , first  photo teleskop , last photo is the  my  last step ,  which button should  I have press?

      Hi folks,
       
      Just wanted to share my bloodmoon experience with you in this blog.
      It was quite challenging, ice on my balcony, camera falling out of telescopes and tracking challenges.
      But in the end it was a wonderful experience, you can read it here:
       
      https://www.astroforum.space/blog/my-first-bloodmoon-experience
       
      and i've included a (gittery) timelapse + final image. 
      Please let me know what you think, should I keep the stuff that goes bananas for myself or share it with you folks? 
       
      Clear skies!
