Here is my first attempt at imaging the Hubble variable nebula! Unfortunately I only have two frames spaced out a month between each other but there appears to be some activity present still! I took this image from London which was shown to be a challenge with the light pollution (as well as the full moon in the second frame). The first frame was taken on 21/02/22 and the second was taken on 19/03/22. I'm, hoping to continue this project and take frames at more regular intervals too. The equipment I used were : -ASI178mm -Nexstar 5SE alt-az mount -William optics ZN73

I took this animation of a sunspot in region 2936 over the course of 4 days! Unfortunately the conditions during some days were not optimal but I think its interesting to see how it develops over time! I took 4 separate videos of the sunspot each on different days and then stacked the frames of those videos separately. Once I did this I layered them on top of each other to create this gif. The first frame was taken on the 30th January. Equipment : - ASI178mm astrophotography camera - Nexstar 5SE - Baader ASSF solar filter

Just went out tonight and decided to try do the spectra of one of the stars in Pleiades! I think it has actually turned out pretty well I just wanted to confirm and see your thoughts on how the graph looks!

Ah yes, I took multiple images of the spectra and then stacked them up to try and get a bit more detail through!

Ahh I see! I will try to get the correct one next time! I am wondering now though, could I have gotten the two ends mixed up? By mirroring the image it somewhat looks more correct than the original..

Got it! I do have a few other images I took with my DSLR camera but I have yet to look at them in much detail yet, though with my DSLR I believe the entire spectra should be present including the zero order so I may have a look at that too!

Of course! Thank you for all these links I shall have a read through them now! Here is what the results come out as on the calculator :

I took 60 20 second exposures in red, green and blue totaling to 180 20 second exposures. Here is a list of the equipment I used! Camera - ASI178mm Telescope - William optics ZN73 Mount - Nexstar 5SE alt-az mount Filters - RGB Processed in astro pixel processor!

Recently I took this image of the Orion nebula and I'm pretty happy with how it turned out! The image is false coloured since I use a monochrome camera (ASI178mm) but I think it still looks pretty good! I'd be happy to hear your opinions and any improvements you would recommend!

Thank you for all the help so far! I may need a bit of help on producing that calibrated spectrum since I am not quite sure how to do that.. I used a monochrome camera for this spectra (ASI178mm) with my william optics ZN73 and the staranalyser 200 which was about 45mm away from the sensor. I'm not too sure what you mean about the brightest of the two spectra nearest to the zero order though.. Sorry for not knowing much about the process of spectrometry, I have only recently begun! Here is an image of the spectra produced without taking a cut from it : 21_16_45_lapl5_ap4930_Drizzle15.tif

Good evening! I recently got my hands on a star analyzer 200 and took a glance at Sirius. As a result I was able to gather this spectra from the star. Although I am struggling to annotate it and make some observations of the star. I also feel as though some of the absorption lines are due to atmospheric interference. Any advice or tips would be appreciated! The software I'm using is Visual spec for reference!

By the looks of things I'm still not receiving anything on the hydrogen line.. Is there a possible rig you would recommend for doing radio astronomy? I can't seem to find any antenna or satellite dishes that are suited for the hydrogen line.. Could I have done something wrong with the wiring too?

Oh! Well this is actually the second time I've tried making a cone antenna and this is the largest I've made so far.. I mostly used a bunch of amazon boxes to construct it and after realizing I didn't have much, I decided to create a mesh instead for the foil to wrap around. Of course this sacrifices durability and structure but hopefully it should still work! With the probe I didn't have a special adapter so I have made sure to keep the outer mesh in contact with the foil on the inside and the copper core probe separate. At the moment I am trying to get it to work on my windows computer but once I see a sign of the hydrogen line I'm planning to try and automate it on the raspberry pi and build a map of the milky way (I may also turn it into a community project on my website if possible). I haven't attempted putting it outside yet but I'm planning to tomorrow hoping that it doesn't decide to rain (or rip apart my antenna..). I will give an update once I attempt this!

Ahh interference could be it since I have only been testing my setup in my room nearby to my computer and other devices.. Is there a specific frequency for the hydrogen line to focus on by any chance? My setup definitely isn't the best as I've tried to work with cardboard and tin foil. I made a horn antenna as seen below, it definitely isn't the best construction but I thought I may be able to see some results from it. The waveguide is 15cm by 15cm and the copper core is roughly 5cm in length. I think I have a complete circuit by keeping the outer copper mesh in contact with the foil lined on the inside but I may be wrong.. I use a generic nooelec rtl-sdr and I also use the sawbird hydrogen line filter to try and increase my chances of receiving a signal. Thank you for the response!

Good evening all, I am currently tearing my hair out at why I keep seeing these peaks along the hydrogen line and I so far have had no success in observing the actual hydrogen line peak.. I was wondering if someone had an answer to the issue at hand here.. Is this normal to see or is there something completely wrong? Any help is greatly appreciated!
