Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation  as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.

I like your avatar! I am a Manchester United fan myself. Likely it was M42 the Orion Nebula.

The Orion Nebula (Messier 42) is located in what is often called the "sword" of Orion, that is a line of stars that come down below the 3 "belt" stars. I've arrowed the nebula in red in this photo and Betelgeuse is indicated by the green arrow:

As much as I hate to reply to a Utd fan  😀 It certainly sounds like the nebula, it’s unmistakable when you see it, unlike anything else you’ll see visually

Haha. Thanks for the info. MANCHESTER IS RED!

Here is a bit of red from the past slightly off topic but had to as an ex Manc. Sorry

When I first looked at the nebula with Binoculas a month or so ago I saw exactly pretty much how you described OP, multiple stars surrounded by a haze of briliant blue and white light. Stunning. It wasn't 'til I took a picture with my phone attached to the binoculars that I could see more colours. Sadly Orion is too low in the nightsky now to observe properly but I'm going to be taking lots of snaps again later in the year. Seems the best time for viewing will be late November here.

Are they applicable to all telescopes?

The UHC type work better with smaller scopes than the O-III type. The CLS type barely have any effect in my experience. These things only work with nebulae (ie: not galaxies or clusters) and the improvements are subtle rather than startling but the contrast in the nebulosity is improved to some extent.

Not unusual to "discover" things? lol. I remember, as a kid, being on holiday in N.Wales
(better seeing) and seeing this "little cloud" in the same place on successive nights... 🤔

Binoculars showed it to be the Pleiades! My eyesight (acuity)
was/is never THAT great - Even with prescription glasses! 🤓

Thank you @John:icon_salut:

I would like to say; that I find the Explore Scientific CLS filter to be a tad better than the Baader Planetarium Contrast Booster filter. Maybe it's just me! Others may tend to agree or disagree as @John has said.

The Contrast Booster and CLS filter are quite different to the UHC and O-III filters.

The CB and CLS are broadband filters. The UHC is a narrowband and the O-III is a line filter. More on these classes of filters here:

      Hi all! I've been out of the game for some time now but nice to see familiar faces on SGL! I hope everyone is well and keeping sane and safe!
      Lots seems to have changed! New cameras, new software, new lots of things! It's hard to get back up to speed after a few years. My Dad (Mick J) keeps me updated. The general image standard is now so high it seems! 
      I have a bit of a natural break in work and life things so enjoying some time in Crete with other half's family currently. First time using portable set-up for me and to be honest a lucky capture with the comet in the frame mostly by accident!
      Approx 55 minutes total of 30s frames and some 10s frames for M42 core, ISO 400. Modded Canon 450D, Samyang 135mm F2. Skywatcher StarAdventurer.
      Similar version of lockdown here so taken from city location and passing cloud but happy to just have some time to enjoy a bit of hobby time! Processing gradients wise was tricky!

      Today I finally edited some data I've had for a while. It's a widefield shot (50mm prime lens) that was used on a modified Canon 600D. The end result is about 50 x 3 minute exposures, ISO 800 f/3.5. It was also shot with an IDAS D2 light pollution suppression filter riding atop an iOptron SkyGuider Pro. The Eastern skies when I shot this are full of street lights so there were some nasty gradients.
      I also realised that the camera lens pulls itself in when the camera is switched off, which meant that even though I'd taped the focus ring down, my focus had changed and I couldn't use flat frames anymore, resulting in the horrible dust motes. Ah well, show must go on! Speaking of flat frames, I have a video on them on my YouTube channel and a post on my website.
       
      I hope you enjoy the photo. It was actually quite difficult to process in a way that doesn't destroy any details in Andromeda. Also, because it wasn't dithered there's a lot of walking noise in the image that also ruined definition.
      Just... appreciate it from afar, and don't zoom in! 😂

      Hello all,
      I always been fascinated by astronomy and finally purchased a celestron nexstar 8se. Setup went smoothly but I'm a little stuck on the lens. I attached the star diagonal to the telescope and focused in on an object. I was able to see a part of the leaf on the plant in my house and I attached a picture of that. Moving the telescope left and right allowed me to see other things. I then took out the 25mm lens and can see through that when not attached to the telescope. I can see my sandals and feet through the lens and attached a picture of that. I then inserted the 25mm lens into the star diagonal and that's where all hope gets lost. I see white (assuming that's my wall) and yes the cover on the telescope is also off. No matter where I move the telescope. All I see is white. I tried last night in clear skies and pointed towards some clear stars using the skyportal app to align but I didnt see anything except pitch black through the lens. I also played with the focus but nothing. Am I doing something wrong, I would think the 25mm wouldnt be so zoomed in that I cant see anything? Thanks for any help you can provide me. Looking forward to exploring!!

      Hey Guys, 
      I run a Youtube Channel and as part of that I like to live stream the telescope.  But the problem is lack of consistency.
      Equipment:
      Orion EON 110, Meade 10" SCT
      Orion Mount - Exos2-PMC. Meade Mount 'push to' alt az with clockwork drive
      APT, SharpCap, PHD2, Stellarium, ASCOM Hub
      Focal Lengths Orion 660mm, Guide Scopes 188mm, SCT 2500mm
      Powered USB for ZWO cameras (120 and 294)
       
      Here is what happens:
      Cameras, sometimes work, sometimes don't.  I am not making the mistake of trying to get APT and SharpCap to view the same camera.  I used APT for the guide scope and SharpCap for the main tube and the 294.  Sometimes APT will take an image, sometimes it will do live view, sometimes both, sometimes neither.  It is very distracting to the stream to spend an HOUR turning the computer off and on, plugging, unplugging and replugging the cameras just to get them to image.
      When I do get an image it plate solves at the NCP, but if you move away, setting the coordinates to the scope position or the object I am looking at, it doesn't consistently plate solve.  Sometimes it does, sometimes not.  It is completely irregular and can change within a session.
      Not all three plate solving means even work, for blind solve, 
      ASTAP never seems to work, either in point craft or locally stand alone
      PS2 and ASPS work intermittently, as above
      I did download all the catalogs and they are in the default directories.
      This is very frustrating and I was wondering if anyone else is having this issue or has suggestions.

      I continue my reports from observatories I have visited. This one is very special for me, I did my education in astrophysics at this place in the 1990s. My girlfriend and I took the car this weekend and visited Saltsjöbaden for a walk, only 30 km from where we live. We ended the walk up at the Stockholm's Observatory.
      Some photos from this beautiful place:

      One of the observatories at this photos is the astrograph which I already earlier had written about.
