Subreddit Rules


Before posting, make sure your post follows the subreddit rules otherwise they may be removed.


  • Rule 1:

  • If you're totally new to telescopes and astronomy, please read our Beginner's Quick Guide to choosing your first telescope which is sticky'd to the top of the subreddit. Failure to read and posting "which telescope should I buy" will result in your post being removed and you being referred to this guide.


  • Rule 2: Petitions/surveys/crowdfunders

  • Links to petitions, surveys, crowdfunders, and other advertisements to sell your own products are prohibited here. There are other subs and communities for this. You can post used item ads here, but do post them on other communities or websites such as Cloudynights, Astromart, etc.


  • Rule 3: Be civil

  • Non-civil behaviour such as insulting, flaming, etc, will not be tolerated. This sub is a place for everyone to learn and help each other, and such behaviour only does bad things to everyone involved.


  • Rule 4: Direct links

  • Direct links should be accompanied by commentary as a top level comment, and should be a source of discussion. Not providing commentary, or posting content from a single source will be assumed to be attempts of driving traffic, which is not allowed here. Self promotion is only permitted to active members of the community.


  • Rule 5: Images

  • Images must have a top-level comment containing acquisition and processing details. This includes your gear as well as any processing you did to the image. This enforces quality, encourages discussion, and benefits everyone. Images must be taken by you, with gear which you own - remote or professional services such as DSW or Hubble are not permitted. Concept art is not permitted, nor is content not relating to visual astronomy/telescopes. Infringing posts will be removed.


  • Rule 6: Titles

  • Titles should not be 'clickbaity' nor self-deprecating - we're all here to learn so there is no point in calling yourself a 'noob' and/or putting yourself down. Titles should be descriptive about what you're discussing/posting.


  • Rule 7: Low effort content

  • Low-effort content such as those complaining about the weather (we get it, clouds are bad), simple questions that usually result in one line responses (these should be posted in our weekly discussion threads instead), general 'shitposting', memes, etc. are not permitted in the subreddit. r/telescopes aims to be a high quality sub where users can discuss all things telescopes and astronomy, but allowing such repetitive and low-effort posts will drastically lower the overall quality of the sub.

I broke my brand new AVX mouynt

So I fucking knocked over my brand new Celestron AVX mount. I was trying to mount my C11 on it and I couldn't get it to fit into the mounting head, and the mount tipped over. Unfortunately, I made the mistake of putting the counterweights on first, so when it tipped it broke the housing between the EQ head and the counterweight bar. I'm wondering if it will still work and, if not, if someone could direct me to the nearest ledge. Thanks in advance. PS please forgive the typo in the title I don't know how to fix it.

What kind of tripod?

I’m looking into getting a 6” / 150mm mak or sct. I don’t want a motorized mount but a sturdy manual mount. Current contenders for the OTA are celestron C6 or SW skymax 150mm.

I live in bortle 8 skys so really only focused on planets and the moon.

Any recommendations on a nice sturdy tripod mount?

Saturn

How do I get more detail with planetary targets? I waited till about 10 minutes before sunrise so that the sun would illuminate the background then I started taking pictures with my iPhone on the eyepiece of my Celestron 8SE. I would like suggestions that do not involve post processing.

I can't decide to choice 6"-8" apertura for beginner

Good day!

I cannot choose a telescope for myself.

I will tell you about my wishes and approximate goals.

I move a lot from place to place, so I want to choose something not too heavy (not EQ6-r mount ). At this point, I chose to mount the EQM-35. Total weight up to 30 kg in full assembly. But I can't decide on an optical device. At first I wanted a 150mm Newton f/4 with a tube length of 53cm and weight around 6kg (TS Photon). But also considering a 6" or 8" SCT. I know that the maximum weight of devices for this mounting is somewhere around 8 kg, so I am thinking about SCT.

I have not had professional telescopes yet, but I have many years of theoretical knowledge about various optical schemes, astronomy and astrophysics.

First of all, I would like to observe distant space objects like Messier objects or bright galaxies from the NGC catalog. Observing the planets would be a nice bonus.

I have a DSLR camera, with which I would like to start doing astrophotography, and then (unknown when) move on to other more specialized devices.

Considering the long focal length f/10 SCT, I heard that they are too dark for visual observations. In my current area of residence - the night sky on the Bortle scale changes from 5 to 3 or even 2 on the most favorable moonless nights.

So I am torn by doubts about the 130-150mm fast and short Newton, or the closed tube 8" SCT, because there is enough dust here.

I've heard that the 8" SCT performs quite well in all types of observing. The Newton for deep sky astrophotography is even better.

But I'm not sure that working with Newton on this mount will bring pleasure. Maybe the 8se on a different one than the EQM-35 pro would be much better with minimal weight change?

Please share your impressions of your "portable" SCTs and Newtons, and help me choose a cool thing for my own birthday. Thank you.

By the way, the bank - up to $1.8k +-

Old telescope found in garage

Model: ST-60900 by “Greika optimal instruments”

Found it today and would like to know more about it. 1- Is it supposed to be point to the moon, stars or really-far-objects? 2- The image looks a little bit dark, should I open it and clean the lens?

there are more doubts that would come when those are answered so i’ll be checking comments all the time ps: I’m a complete newbie with this so please help :)

Wow

So last night I was star hopping to find m81 and m82. After a while I found the two galaxies and it was so exciting and cool. While observing I swear that I could see some of the galaxies structure. And I have a 80mm refractor. Now what did you see when you found these two amazing objects?

Will I see any issues using a 1.25" adapter in a 2" focuser?

I've previously owned a 6" dob which had a 1.25 focuser, but after selling it a few years back I now have an 10" dob with a 2" focuser.

The eyepieces in question are a 6mm Delos & a 24mm Panoptic, both of which are 1.25"

The thing is these eyepieces are expensive, so I'm just wondering if there will be any issues getting them to focus or a loss of quality when using the 1.25" adapter?

Should I go for it at 300? What should I be on the lookout for?

It’s a zhumell z8 dob telescope. Available for 300 dollars. The person just dropped it from 400. Check the picture. What do you guys think is it a good deal? What questions should I ask the person before going to check it or finalizing it, if at all? Thank you.

M81 & M82

Bode's Galaxy (Left) and the Cigar Galaxy (Right) form a captivating celestial duo within the Ursa Major constellation. Bode's Galaxy stands out as one of the most luminous entities, residing approximately 11.5 million light-years away from Earth. Meanwhile, the Cigar Galaxy earns its moniker from its elongated form as observed from our vantage point, possibly owing to its vigorous star formation activity. It resides approximately 12 million light-years away I will revisit these amazing galaxies for a closer look with my C5. Stay tuned!

2 hrs integration, 3 min subs, bortle 5, AT60 refractor telescope, 30mm Svbony guide scope, ZWO ASI183MC Pro, ZWO ASI120MC guide cam, Optolong UV/IR Cut filter, ASIAIR Plus, Celestron AVX EQ Mount, processed and stacked in Pixinsight.

I have an eye relief question

We just got our first telescope. It is a Zhumell z114 portable. How tricky should it be to look into the scope? I have to move my eye around and towards and away from the eye piece to get a full view (not tunnel or blacked out).

Is this just the way telescopes are or is this one faulty? I don't have this issue with binoculars.

It has been cloudy since it arrived so all we have looked at is tree branches across the field.

TIA

Shipping Date for Explore Scientific Truss Tube Dobs?

Has anyone recently ordered an Explore Scientific Truss Tube Dobsonian telescope? I ordered one (the 16" one) from B&H Photo (12 mos. interest free with Payboo credit card) on 3/27/24, but I have yet to hear anything from the shipper in China. B&H shows my order status as "drop ship," which means that they've pretty much washed their hands of any responsibility for shipping notifications. I've gone to other sites that show that particular scope (and similar) as "out of stock," and one shows an expected shipping date of 10/31/24! So, I'm curious whether anyone who ordered the scope from another dealer may have actually heard something about availability from the maker/shipper. Thanks for your help.

Telescopeodel ?

Hi guys, Found this scope on the market for about 300€ Can you tell what it is and if it’s worth? From what I can see it’s missing the finder and eyepieces.

What about a decebn tripod for this telescope, how expensive would that be?

It's time for an upgrade. What to do?

I ordered a scope that's on backorder. Should I get something else instead?

I have an older NexStar 4SE. I appreciate the GOTO mount, but the scope has its limitations. I have a Starsense unit from another scope that I plan on adapting to use with the new scope.

I've ordered a Celestron Omni 150 OTA ($300) that I plan on putting on a Celestron Heavy Duty Alt-Az tripod that I have laying around although I think it's pushing it on capacity.

My plan is to ultimately upgrade the mount to a GOTO equatorial. Maybe I'll play around with some photography or maybe not.

The Omni 150 is on backorder. It's not to late to change my mind. Is there something else I should consider in that price range that might be equivalent or even an upgrade?

Confusion - eyepieces

Got my first telescope. It's a Celestron popular science az 100 with a 6" aperture and focal length of f/6.

I finally got everything lined up from the red dot finder to my phone which finds celestial objects for me.

2 nights ago I had the best night yet for clear skies. I don't know where the moon went except to say moon rise is like 3 am in my are so I poked around looking at stars.

I was looking at the beehive cluster with a 25 mm eyepiece and then changed to a 10 mm and then there just weren't as many stars. I was expecting to see a bunch of stars clustered in one place.

I switched back to the 25 mm. Every time I've used the 10 mm no matter how I focus it it's like nothing's there.

What am I doing wrong? Can anyone explain it to me? I'm new to all of this.

Want a Newtonian reflector, but not tabletop.

Hey guys. I want to buy my first telescope and I want it to be a reflector. Skywatcher Heritage looks awesome, but I’m not a fan of the tabletop scopes. Can I put one like that on a tripod? Or does that not work for some reason? Advice would be great here.

Good desert viewing locations

I'm going cross country to California for two weeks in June and am taking my 12 inch dobsonian with me. We are planning to camp in a few desert locations on the way. Does anyone have any recommendations for camping or viewing locations? California death valley area. Utah Colorado New Mexico Texas and Kansas are some states I will be traveling through.
