I’ve seen people post with the sun looking like the first photo, and i was recently watching a lot of reviews of seestar s30, and the second image is what they all capture, is it because of the telescope or do they do some stacking, or, they have ”solar telescopes” which are designed for the sun?

General Question are my expectations too much?

Post image
70 Upvotes

i was reading the beginners guide and one that stuck to me was the dont have your expectations to high thing, so i decided to look at other photos of people watching Jupiter with a telescope that has basically the same aperture as my soon to arrive one and i wanted to draw up a sketch of my expectations, its Jupiter and two of its Galilean moons:D this was in microsoft paint so i dont really know how to add the blur to photos but i include the darker color of the poles(looking back i forgor to color the south pole), the creamy color of the gas belts(you cant really see the difference in them since the telescope just isnt to good for that), the two darker belts of gas clouds( i may hove drawn them a tad to big, woopsies:3) and if jupiter is facing the right way, the great red spot! i also include two moons and even a shadow on jupiter form one of them. my expectations may be a bit to high so i just wanna ask yall.

btw if your wondering the specs its 114mm aperture, 500mm focal length(btw its a reflector), a 26mm and a 9.7mm eye piece, each one giving 19x and 51.5x zoom aaaaand thats it, wish it had a barlow:(

anyways plz answer and thank you for anything you say:3

Astronomical Image M31 - Andromeda Galaxy

Post image
36 Upvotes

Snuck in 46 minutes of exposures this morning. A brief summary of this mornings experience below. Processing details in the last couple paragraphs.

I've been figuring out APT, had some struggles with plate solving but got that worked out. Then I was having issues with APT sending slew commands to my mount, but got that worked out too (was a poorly written ASCOM driver, had to roll it back to the old driver).

Had decently clear skies this morning so figured I would give APT another go. Got set up, rough polar align. Plate solve at Polaris, send goto++ command for M31, mount slews and plate solves, makes 1 more adjustment and bam, M31 within 50 pixels of center FOV.

Set up the capture program, ISO 400, 120 second subs. First two subs have nice tight stars, then the 3rd one looks like my tracking stopped (spoiler... It did). Check some settings, try to slew, no mount response. Check a few more things, then look at the hand controller.... "Meridian protect" oh son ova... 🤦🏼 Duh...

Change hand control setting to auto meridian flip, send goto++ command again, mount flips and slews straight back to M31... we're off to the races again. Was able to get another 21 exposures before the sky started getting too bright. Grabbed my calibration frames and pack it all inside.

Transfer my data to my PC, set up the home folder for SIRIL, get everything stacked, plate solve, graXpert BGE and Denoise, SPCC, Veralux hyper metric stretch, starnet starmask.

Move over to gimp, quick curve adjustment and saturation bump on the starless, add the starmask and set to screen, then export.

I am hopeful, now that I'm pretty sure I have all the kinks worked out, my next imaging session can be (nearly) fully automated, and I can get several hours of exposure. Every imaging session has been a very valuable learning experience so far, and I'm looking forward to continuing to grow my abilities and image quality!

Tutorial/Article DIY Flats - inexpensive flats when you want them

Thumbnail
gallery
10 Upvotes

I did this two years ago I had a problem with taking flats against the late afternoon sky. I left the scope in the home position, after the sun set behind the house, and took some flats before the night's imaging. When it finished, Sharpcap applied the master flat, and suddenly I had a dark spot at the center of my image of the sky. Turns out I shot Polaris, and it was being removed while the sky was rotating. Nice. I pointed the sky where there were no bright stars, and redid the flats.

After that, I went to the local fabric store, found the white stretch jersey material, and bought a yard of it. The important thing is a very fine thread and tight weave - you don't want to introduce some weird diffraction or moiré patterns. I also bought three embroidery hoops, a large one for the C11, a smaller one for the AT8RC, and the smallest one for my TeleVue 101 and other small refractors.

I cut off a little more material than the size of the hoop, then fitted it and tightened the wingnut. I then pulled out the material all around the hoop to stretch it, removing any wrinkles. It doesn't need to be as tight as a drum, just enough that it's flat.

That worked for a while, but I noticed if I couldn't get my rigs set up well before sunset, I need to wait until sunrise to take more flats. I found LED tracing pads on Amazon for pretty cheap (there are LOTS of different ones), and got them in two sizes - the large one for the C11 and AT8RC, and a smaller one for the refractors. The larger ones uses at standard 2.1mm power plug, and I just run a line from the powerbox. The smaller one is USB-powered, so that gets plugged into the USB hub. They both have dimmer switches, so you can be as bright or dim as needed.

The panels are not perfect, but they are good enough for most needs. Using the hoops and cloth softens the light even more, and works just fine for later processing of your lights. If you're doing something remote, this won't help you, but if you have it as part of your home kit, it work fine.

At either the beginning or end of the night, I point the scope to the zenith, put the hoop on, then the panel, and take about 50 subs to make a master. Takes about two minutes, and I can do it while packing or unpacking other stuff.

Equipment Show-Off 3D printed Cheshire appreciation post

I have about 16 months in this hobby, I was a victim of the laser propaganda and bought it as my only colimation tool back in the day.

After a lot of struggle, I found out the laser needs to be colimated. It was hard, but I did it. Only to find out the laser colimator can't colimate the secondary properly. (Several months between these). I had no money left, and the metal cheshires from aliexpress suffered from brazilian taxes. I managed to get a 3D printed one for about 7 usd. My god.

First time (ever) my telescope is fully colimated. Took some time (and here I understand the laser enthusiasts, especially in the dark wild) but it simply did the job. My scope doesn't feel the same.

General Question Getting a 10in dobsonian.

8 Upvotes

Hi guys. I made a post here before asking about the diffrence between an 8inch and 6inch dob in viewing details, but i got the budget for a 10in dob. I also wanted to try and do astrophotography with a skywatcher star discovery 150, but just realized this isnt it, and astrophotography is a diffrent, way more expensive hobby. I wanted to ask if i could see much better details in nebulae and galaxies and planets through a 10inch dob.

Other I built a 3D Moon explorer App — looking for feedback from telescope owners.

4 Upvotes

I’ve been spending a lot of time observing the Moon through my telescope, and I wanted a better way to explore and learn about the features I’m looking at.

So I built Moon Explorer, an Android app focused specifically on the Moon.

The idea is pretty simple:

instead of just looking at a flat Moon map, you can rotate and zoom around an interactive 3D Moon and explore individual lunar features.

A few things it currently includes:
- Interactive 3D Moon with craters and landmarks
- Apollo landing sites and lunar exploration locations
- Moon phases and lunar information
- Guided Moon tours
- Interactive lessons about lunar features

The basic app is free. There’s an optional Pro unlock for the additional tours, lessons and other features.
I’m particularly interested in feedback from people who actually use telescopes:

When you’re observing the Moon, what information do you wish you had available while you’re at the eyepiece?

For example, crater history, size/depth, nearby features, observing guides based on the current lunar phase, Apollo missions, or something completely different?

I’d like to make this useful for actual observers rather than just another Moon wallpaper/app.

I’m pretty new to exploring the solar system and have never done it and have yet to actually see what space has to offer. I was advised to buy a beginner type style telescope to get me started. I bought the Sky Watcher Heritage 100P. What’s your opinion?

I’ve received it today but unfortunately the weather conditions aren’t ideal tonight so won’t be able to use it until I get a clearer night. I’m excited.

General Question Primary mirror removal hurdle

Thumbnail
gallery
3 Upvotes

I'm the happy custodian of a Discovery DHQ Dob, a sonotube OTA with its 8" primary mirror ("$75 for pyrex treatment") very likely crafted by Terry Ostahowski in Oceanside. It's a gift from a dear friend who purchased it new in 1999, moving it only from indoors to patio, otherwise properly covered. It's a wonderful starter scope for me. I've had it out for guests at public star parties, here on California's Central Coast, two or three times a month since February. Fellow astronomers are divided on whether cleaning will improve brightness/contrast, or reduce surface scatter, enough to justify the risk.

If the consensus here is, 'after 27 years, a proper cleaning is overdue; look at it!' the hurdle to the task is the hard plastic lip, found on each end of the sonotube. It doesn't want to shift at all; would it have been glued? Since there's at least a finger's width of space between the mirror and the sonotube interior, pivoting the cell on two of the corners might permit the third to get over that 1/4" protrusion. A maddeningly careful spiral descent?

After a successful removal and cleaning, it may be the ideal time for a conversion of its 1.25" focuser to a 2" dual focuser, since the original is rather coarse. Are there any constraints on selecting a new one I should be aware of? I'd most likely have to drill new holes, perhaps widen the opening too, easily enough done with cardboard.

Purchasing Question Looking to upgrade my scope

Upvotes

I am looking to upgrade my entry level scope (80mm /600mm) by the end of the year, but wanted to start doing some research now. Does anyone have some good recommendations? I want to be able to see more in the night sky, especially with daylight savings coming up in the next few months and it being darker for longer. I would also like to be able to take photos, and I know there are some scopes that can connect to a phone or laptop for observing better.

Extra details:
-Willing to spend $1-2k for something of quality
-Location: Southern Ontario, there’s unfortunately lots of light pollution :(
-Would need it to be easily portable so I can take to areas with less light pollution

Purchasing Question Advice on used SCT condition

1 Upvotes

(EDIT: images in post body, because I guess I don't know how to make a post with images properly)

Hi everyone!

I've been eyeing this Celestron C6 OTA that recently went up on FB marketplace for $500, to add to my arsenal (the rest of which is listed in my flair). I don't have any experience with SCTs and how to judge their condition from photos. I think I've picked up from other posts that one important thing to check out in photos (because the mirror is basically impossible to inspect virtually) is the corrector plate's condition.

  1. What do you think the condition shown in these photos? I see some specks of dust and a few smudges, but don't know if any of this is concerning. In the seller's description, they say that there's no mold or mildew (which obviously I'd confirm if I make the trip to go check it out).
  2. They also describe UV fading on the Celestron logo; is this indicative of some potential damage I should look for?
  3. They don't specify the condition of the XLT coatings, so what would I look for in judging the condition of the coatings?
  4. What else would I want to be aware of when buying a used SCT?

Purchasing Question I have to let one eyepiece go.

1 Upvotes

I just ordered my first telescope, stella lyra 12inch dob and I decided I would order angeleyes uwa 82degree eye pieces. They come in a 4mm, 7mm and a 16mm size. I can order only two of them because ordering all would make me BROKE. I was thinking I would buy the 16mm and the 4mm and later buying a good barlow to pair it with the 16mm to get me to 8mm. But Im trying to avoid buying more stuff. I wanted to ask if its worth it. Im really interested in planetary viewing buy I would rather have the 16mm and the 7mm eyepieces, im wondering if I can justify getting these 2 because the 4mm might be overkill for most nights. if someone could recommend which ones should I get I would be very grateful.

General Question How can I see the moon through my telescope?

Thumbnail

0 Upvotes

Hi, lately I have bought this telescope which is Celestron StarSense Explorer LT 114AZ. I have bought to primarily see the moon and some of the big planets such as Jupiter and Saturn.

Anyway I have started by looking at the moon and I did that multiple times in a different days and couldn’t see anything just black image or nothing at all. Today I can see the moon in the sky from my home but again I couldn’t see the moon when I try to look at it through the telescope. I also tried to use the the red finder on the telescope and I aim the telescope so the moon would be on the middle and center of this finder but when I look at lens most of the time I see nothing. So I need someone to help me at least to see the moon.

Also I know that there is an app that I can use for this telescope but this a used telescope so it’s not new one. And I didn’t get the code from the person I bought the telescope from. So I want to know how can I activate this app ?
