I've got what I believe is a pretty nasty tilt issue with my setup (astromodded Canon 700D, Samyang 135mm) and after testing the lens with my second camera (stock 700D) I learnt it wasn't an issue with the lens. I also went back and checked some of my older pics from a few months back with the same setup and there was no serious tilt issue back then. I think the problem is that with the project the image I linked is from the camera is orientated in a way that the weight of the DSLR is putting too much strain where it joins to the lens, (the lens is supported in one of those 3d printed ring systems and attached to the dovetail and the camera just hangs off the end unsupported), is there any product I can get that will hold the DSLR and support it's weight so this tilt issue might go away? The test I did wasn't very scientific as the stock 700D was pointing at the comet c/2022 which was towards the home position of the mount while Orion is low in the sky and behind the mount but I feel thjis supports my theory that it's an issue with the weight of the unsupported DSLR in this exact orientation that is the issue.

I'm looking to upgrade my setup over time and I'd like a power supply that won't also need upgrading every time I get a new piece of gear. The equipment I plan I'll need to power will be an ASIair plus, an ASI 533MC, an ASI 120MM guide-cam and either an HEQ5 or an EQ6 mount. The minimum I'd like to be able to power all this equipment for a minimum of 6 hours on a single charge. I know that Watts = Amps * Voltage but I just get lost when thinking about Ah or Wh and how much power is needed and does the 12V 5A rating on the ASIair cover the power required by the things plugged into it like the cooled camera? I'd prefer a LiFePo4 battery but obviously they cost more, I'm currently looking at a few options and don't know if the lower power ones would be enough. I feel like this 500Wh will surely be enough, maybe a bit overkill and is a good alternative to the Jackery 500 without the brand safety and no reviews https://www.amazon.co.uk/dp/B0B5NGD183/?coliid=I1QN7E8MU7GBW9&colid=2M3KWHBM794J5&psc=1&ref_=lv_ov_lig_dp_it This FOX Halo 96K would would be the best one if it meets the requirement, cheapest lithium ion battery but it looks very transportable https://www.foxint.com/home/product/fox-halo-96k-power-pack?c=power-packs Not sure about this one from Halfords but it's the cheapest and maybe it is also an option https://www.halfords.com/motoring/battery-maintenance/jump-starters/halfords-6-in-1-jump-starter-power-pack-654898.html Thanks for any help!

I've made a report to the United Kingdom Meteor Observation Network, waiting to hear back from them.

I've checked that site extensively for any satellites that might have passed through my camera fov at both 03:34 and 04:34 ± 5 mins and there weren't any that passed anywhere close to the heart and soul nebulae (I'm not sure if that site accounted for clocks changing on that night so I checked both times). Also it was a 70s exposure so if a plane was flying that high that its wing and tail lights became one line it would surely not cross the field of view in a single exposure.

Is it possible that because I was imaging in a relatively narrow fov (relative to how long shooting stars can be) that I caught the middle section and the taper at the end of the fireball happened out of frame? Most images of shooting stars you see are super widefield. There is a very clear change in thickness at the end near the centre of the picture.

A plane is one of the things I'm sure it is not. It's far too bright in the linear image and there aren't any blinking lights indicating wing or a tail lights. The object in question is a solid line and ridiculously bright and there are more than 3 distinct lines in the section in question. Is it possibly deorbiting space junk and if so do you know if there would be a way to confirm it? I'll attach a comparison shot from the same night of a very bright plane in its linear state and as it appeared in the camera.

On the morning of 30/10/2022 I was out doing some DSO astrophotography in Cassiopeia and Perseus on the Heart and Soul nebulae and the Double Cluster, which would have been located in the west-northwestern part of the sky at that time. My location is in Northumberland and I am 55 degrees latitude. My gear used was a Canon 700D astro modded, Samyang 135mm f2, star adventurer 2i and the exposure length was 70s. At 03:34:38 in the morning (the clocks went back that night so my camera read 04:34:38) I saw a bright green flash streak across the sky near the constellations I was shooting, I'm 100% certain it was a shooting star. When I went to check my camera after it had finished the exposure it was on I saw the most recent image had a streak through it that was extremely bright, I think it is the shooting star I saw. I'm trying to find a definitive answer however because i'm not certain if it was just a coincidence. It can't be the ISS because it wasn't visible from my location at the time of the photo, it looks absolutely nothing like a plane flying through an exposure, some people on other forums suggested a starlink train since there was a launch recently, however I checked a map of their satellites and they are almost all south of 55 degrees north and therefore surely don't appear in the northern side of the sky for me? Also satellite trails tend to be really thin at the focal length I shoot at of 135mm and this streak is very thick, changes in thickness across the picture and turns from a single streak into multiple streaks within the same picture. I checked heavens-above.com for any possible bright satellites flying overhead at exactly that time through exactly that small part of the sky and there were none, however I'm not sure how comprehensive a list of satellites that site has. I'll upload some images in varying states of processing, the streak is so bright that when the data is linear it is by far the brightest object in the picture and has a distinct yellowish colour to it. When I did the starxterminator and created a star image it had a very distinct green colour to it too. Attached are the Linear data that was calibrated in Pixinisight with PCC, A stars only image that was colour calibrated > automatic background extraction > noisexterminator > SCNR > starxterminator > EZsoftstretch > slight saturation boost The image as it appeard on my camera. Note the top left corner where it splits into multiple lines, towards the middle of the line near the soul nebula there is a fuzziness coming off the line and at the very bottom centre of the line it becomes noticeably thinner.

Took this over the weekend of the 7th and 8th during the full moon. Wanted to test out how my Skytech triband filter would perform under those conditions. Think I went a bit to aggressive on the star reduction in the processing, photoshop bit is still a massive struggle for me 😅 Best 80% of 7h40mins of lights totalling 6h27mins. Asto modded Canon 700D, Star Adventurer, Skytech Triband filter, Samyang 135mm.

I have recently ordered a Skywatcher 200p dob, I'm hoping to receive it soon. But something I've been worrying about has been the amount of light trespass in my garden. I've included a couple of photos of the 4 lights, I live near a fairly busy road. I've previously contacted my local council asking for some form of shielding to be installed on the lights, they replied that they would send someone to fix the problem but no one ever ended up coming, this happened around the 2nd lockdown so I wasn't really surprised and then it was Christmas followed by the 3rd lockdown. As a temporary measure, how effective would a garden parasol be to block out the direct glare from these lights when observing? I was looking into doing something homemade with a tarp but the height of the lights makes me feel that wouldn't work. My current thinking is that with one of those big 3m parasols that have a tiltable canopy on Amazon I would effectively block at least 3 of the 4 lights depending on which direction in the sky I want to observe. Thanks in advance
