P.S. I use a Celestron Nexstar 127 SLT

Just a quick question should I use 80% or 70% gain on Saturn with my ASI120MC-S and 2x Barlow using FireCapture.

If you can afford £600 I guess you could get the Celestron Nexstar 127 SLT 😅 Sorry that the travel scope was a bummer, maybe try something like the Sky-Watcher Skyliner 200P, or Sky-Watcher Skyhawk-1145P 114mm (4.5") f/500 Parabolic Newtonian Reflector Telescope. Make sure to read the description and specs before ordering.

Im referring to SA 2i my bad for not referring

If you want a budget of a telescope, I suggest you could get something like the Celestron Travelscope 70mm which is a good beginners amateur telescope. You could try and get other telescopes such as Celestron Astromaster 130EQ, or Celestron Powerseeker but some of those won't produce great quality with seeing objects so try and get a telescope that has multi-coated lenses.

I am thinking of investing for an Evostar 72-ED and I am wondering if that can go well for my SWSA? It will be additional to a Canon 600D, Field Flattener (optional), and a 2" nosepiece to insert the camera into the OTA.

What I do is align the telescope to a star and make sure it's dead center using a high power eyepiece, then tweak the finderscope so it can co-ordinate with the OTA. Then I put my camera in and remember the location of where the object should go by the crosshairs then I easily find what I need to look for.

I use a dew heater for my telescope, the problem isn't the scope, It's my equipment such as my laptop and table.

I began using a heating fan to help tackle dew on my equipment over time, but the problem is that the turbulence can affect my views on the planets. There for I will be stuck in a rut of tackling the dew and trying to keep the seeing from deteriorating. What will you think if my idea is when I finished taking a run through of capturing one planet then turn the heater on to remove the dew?

How I focus my telescope to planets is pointing to the planet and moving the focusing knob side to side and tweaking it and carefully observing the changes of detail on the planet. If the planet is revealing details like clouds belts on Jupiter, cassini division on saturn, then it's good to go. But when turbulence is rife it can be harder.

Focusing can be a pain in the backside..

I use a Canon 600D, I am not sure it has what you introduced me. But is there a way to derotate these in one same axis from a software?

Took multiple handheld shots of the full moon a few days ago and upon stacking and sharpening, I was met with these artefacts (that are noticeable on the near edge of the moon). The artefacts have these smear trails that are from when the Moon is slightly tilted due to the instability of the shots, (because this was taken through handheld and not a tripod it could easily be obvious since the subs have slightly tilted angles. Is there a way to keep the moon at an angle it can stay on then stack using software?

Not until now

Just a quick post on how to fix edge rind, feel free to send me to posts regarding that, FAQ's and tips. Cheers! William

I was told that using a low gain can result in an onion skin artefact, like this

I mean for visual use you can just spectate Jupiter through the scope through the software without recording anything. And also in that case of the FL then that'd be 2400.

So I managed to make a map computation out of my data of Jupiter but there are these dark lines that appear in the image, Is there a way to remove them and blend the separate images together?

My settings from my telescope are: Jupiter - Exposure: 10, Gain: 70 Saturn - Exposure: 57.57, Gain: 70

I managed to get all faces of Jupiter to make a map computation but I keep getting these problems where it doesn't blend in or it cuts off. Thanks for advice

If your using a software to image planets I recommend using FireCapture, if it's for visual purposes I would use SharpCap so it won't be a clutter then. Also I suggest you use a 2x Barlow for better magnification, then that could double the focal length. So in conclusion your telescope is 150mm, and if you times it by 2 you will get 300mm focal length magnification instead.

I could have been half of a terabyte. I got 300 GB left of 1 TB after transferring it all to my hard drive.

3rd August 2022 I went out at 10pm, aligned my telescope and finderscope to a star so it can be easy to align to an object. I used Auto Two Star alignment method with the Nexstar SLT+ remote and aligned to my first target, Saturn! Upon capturing data I took multiple runs of it and since I was very ambitious for it I also made it to imaging it's moons. The seeing was very good and I can easily take a grasp at the cassini division and banding around the planet. Next I aligned my telescope to Jupiter and was able to see the cloud belts and it's beautiful storms and jetstreams racing along the planet's surface. I also managed to get a capture of Callisto in the FOV of my imaging which is a good photobomb. Seeing was very good as I can measly see the minor storms across the planet. Next target was Mars as I aligned my telescope to that and was welcome with a red gibbous shaped disk and I could also see the maria of the planets surface. Seeing was very good although it had alot of turbulent intervals but the results came out beautifully. Out of ambiguity I chose to align my scope next to Neptune and Uranus. Thanks to the help of my 6x30 finderscope I managed to get them on my camera sensor. I took 5 minute 100-500ms exposure at a gain of 100. Seeing was very good considering their apparent size in the sky I stayed up til sunrise as the clouds began to roll in which made a beautiful scenery for me whilst I was finishing up from that night. It was fantastic and what made it better was the ice giants since they're hard to find due to their apparent size and magnitude in the sky.

(Mars is the bright red disk that can be seen in the center and Uranus can be seen up north of Mars) 7th August 2022 For this night I chose to go out and experiment with my 3X Barlow, as the planets have improved in seeing I gave it a shot with that barlow lens. Three planets captured were Mars, Jupiter and Saturn. Unfortunately the seeing came out poor which moral to that is use the right barlow for better images. The more magnification from the barlow, Not only the more larger the image will be but the more blurry the image will get and atmospheric turbulence will be more apparent as well. So I chose to stick with 2X for serious planetary imaging but I am happy to use the 3X Barlow for experimental purposes. Also managed to get captures of Mars with the 2X Barlow Images: 2X Resize (2X Barlow) 2X Resize (2X Barlow) 8th August 2022 This night I decided to go barlowless to take a widefield animation sequence of Jupiter's rotations and it's moons orbit around the planets. Seeing was good considering that there was no additional magnification for the purpose of this sequence. Moons from left to right: Ganymede, Europa, and IO. 10th August 2022 The last night for the week I spent the entire night til sunrise capturing Jupiter's rotation and IO appearing out of Jupiter. Mistakenly out of experiment I used the ADC and 2x Barlow through the threads which made the seeing decline but it is so much better when it is animated. I took Saturn and Mars too and the seeing for Jupiter is good but from the start the turbulence was apparent but improved overtime, Saturn is average since I didn't get much data out of it and the turbulence was worsening over time but amazingly I found Tethys from the short exposure data of it. Mars's seeing was average to good as your can see the mares and it's shape although the turbulence was tedious. My telescope dewed over the night but I used a dew heater to tackle it for the session which I forgot to bring with me at the startup. The moisture in the air was so rife my telescope before and after using the dew heater dewed over swiftly and my equipment looked like it had it been slightly rained on. Thankfully nothing was damaged. Images: Detection of Tethys (Small white blotch on the right of Saturn) 2X Resize It has been a blast taking these and it can be very exhausting and takes alot of effort. I had to go through the moderately cold temperature whilst my equipment dewed over so I needed to use a dew heater for my telescope each night. It has been an amazing experience and having the patience and wait for the Earth to move where I can see them at an appropriate place and time. I will be looking forward to Saturn's opposition for this month which takes place at 27th August. Feel free to ask questions, thank you all for feedback and also feel free to give advice to help me improve more along the way.
