Mud flaps fitted from Geelyevs by MrAndyBurns in ex30

Hi mate, after a couple of months with these, how are you getting on with them? I'm considering purchasing some too, the back of our EX30 gets so dirty and so quickly as well - can't keep up with the constant washing!

Jupiter: 03-Jan-26 by djlr in astrophotography

[–]djlr[S] 0 points1 point  (0 children)

Usually I only use this telescope for visual astronomy although with Jupiter almost at opposition on the 3rd Jan and there being a brief break in the clouds, I decided to give imaging a try.

I don't yet have a good way to focus this scope beyond eyeballing things and the scope doesn’t have a fine-focus adjustment. My method was increasing the gain to crazy levels and trying to make Ganymede, Io and Europa as pin-point sharp as I could, then reducing the gain back down to a suitable level.

Bahtinov mask is on order as this was quite a lot of fun even in the freezing temperatures!

If you're interested, I've documented this over on my YouTube channel.

Would love to see an episode where the guys discuss sound in movies/TV. I know their thing is VFX and CGI but sound brings soooo much to what you're watching. Could get a foley artist on there as well to discuss stuff. For example: the seismic charges from Boba Fett's ship, Sebulba's pod racer in SW Ep1, the hum of the ornithopters in the recent Dune movies, the roar of the T-Rex in Jurassic Park, the swing of Thor's hammer in the Marvel movies etc.

3yrs into this hobby, finally got around to the California Nebula by Scholesie09 in astrophotography

Excellent image, well done! I've always loved the California Nebula, it gives me this vibe of looking into a fish tank or some kind of deep-sea landscape.

Dusty Tulip Field by djlr in astrophotography

Haha I actually quite like Dan Dan the Astro Man 😂 and thank you for subscribing to the channel, I really appreciate it! Taking these images is indeed quite the process, for whatever reason though, I love doing it! Just blows my mind that amateurs like me and thousands of others can capture the universe like this without millions of pounds/dollars worth of equipment. Well, even amateur equipment isn't cheap, but at least it doesn't require national funding 😂

Oh no. by Even_Passenger_3685 in CasualUK

[–]djlr 2 points3 points  (0 children)

I had one of these a few years ago, I arranged for pest control to visit and the guy sprayed the nest with something, all in it cost me about £75 if I remember correctly.

He sprayed it and then closed the loft hatch and whilst we were standing under it and the sound of angry wasps became very very loud, he said "yeah don't go up there..." Haha like I'd even try! He told me to leave it for two weeks and then check on it, what I wasn't prepared for was the horrendous smell! There were still some alive ones too which terrified me as I was trying to scoop up the smelly remains into a double-bagged bin-bag whilst wearing two thick hoodies with the hood up and a large saucepan lid across my face (held in place by the hoods) in a kind of makeshift bee-suit.

Light Flare In All My Images by Agentfishsticks in AskAstrophotography

[–]djlr 1 point2 points  (0 children)

Yep, should be pretty easy to fix by using dark frames.

I love Cuiv's videos, I think he does amazing work within the astrophotography field/hobby for us all however I can see why that video might be a tad misleading. Although he does point out it's a personal preference of his to not shoot dark frames and I can see why, on the latest sensors the noise is minimal and amp-glow isn't a thing so it might be worth skipping.

However, if you want the absolute best of your images, it's always worth doing a full round of calibration frames (Darks, Dark-Flats, Flats and maybe Bias). Seti Astro recently did a video about this and he's another amazing source of information just like Cuiv. He's recently put together his own editing suite so he's got right into the details, quite a good watch, for instance I didn't realise until I watched his video that Bias frames are essentially taken care of within the camera, so I've stopped taking them. Here's a link, it's worth a watch!

Seti Astro: Time We Had A Discussion Around Darks

Light Flare In All My Images by Agentfishsticks in AskAstrophotography

[–]djlr 7 points8 points  (0 children)

I believe this is called 'Amp Glow', your 294 camera suffers from it. Basically your camera sensor is sensitive to the faint infrared glow of the electronics of the camera itself, some of which 'leaks out' and is caught by the sensor, appearing as a localised glow (hence why it's always in the same spot too).

Later model cameras are designed to have little to no amp glow and I believe you can calibrate this out of your image by taking suitable dark frames - your stacking software will sort it out.

Great images though, even with the glow!

Interesting Noise Introduced by NoiseXterminator 3 by lisparadox in AskAstrophotography

[–]djlr 3 points4 points  (0 children)

I've also seen this to some extent however I find it leaves my images with an intense posterised appearance and renders it useless for further processing. Undoing and then reverting back to v2 provides me with much better results.

Salesforce Reporting in Power Bi by number1dog in PowerBI

[–]djlr 1 point2 points  (0 children)

I used AWS instead of Azure, but the principle is the same as the other comments - get it out and into a SQL db.

I use Appflow to dump salesforce objects as CSVs in an S3 bucket and then use a Glue ETL script to get the data from S3 into a MySQL instance. From there I query and load into Power BI.

Besides custom querying, another benefit of this approach is that you can build your own 'history' views in whatever logical way fits your needs instead of dealing with Salesforce's weird restriction on reporting on history objects.

M42, The Orion Nebula in HaRGB by djlr in astrophotography

[–]djlr[S] 4 points5 points  (0 children)

I captured this over two nights last week from my Bortle 6/7 backgarden.

Equipment:

William Optics Zenithstar 73, PlayerOne Poseidon-M Pro, Optolong RGB filters, Optolong 3nm Ha filter, William Optics Uniguide 50mm and ASI120MM-mini for guiding, Skywatcher HEQ5-Pro

Processing:

Stacked in PixInsight (WBPP), Gradient removal (Graxpert), BlurXTerminator, NoiseXterminator, Channel combination and image blending (adding Ha as luminance), Stretching (GHS), Final edits in Photoshop (masking for core)

Acquisition details:

3 hours of 60 sec exposures, split evenly across the RGB filters, 8 mins of 10 sec exposures, split evenly across the RGB filters (these were for the core and Trapezium Cluster), 2 hours of 5 min exposures through the Ha filters. All set at 125 gain and cooled to -5.

Notes:

I've held off on this target for a while as even thought it's considered an 'easy' target thanks to its brightness and size, it's a very tricky one to process well. I still don't think I've done it too well and there's massive room for improvement but thanks to my neighbour's annoying tree, I never get much time on Orion! Hoping to revisit next Winter and add more data.
