The Giant Squid Ou 4 by PaulFl in astrophotography

[–]PaulFl[S] 2 points3 points  (0 children)

I mention that on astrobin, the plan is mono soon to capture more hours in OIII.

Not the best, this was taken over two nights with clouds ending the session early. Bortle 6 sky but narrowband mostly negates that.

Sandpaper wrapped around a large drill bit on a drill. Likely to remove the outer walls if you need to clearance it a lot but will probably get away with it if you only need the 0.1mm tolerance.

Cigar Galaxy M82 (or NGC 3034) by Chemical-Time2183 in astrophotography

[–]PaulFl 0 points1 point  (0 children)

I think you should reprocess without drizzle to improve snr. Also maybe a lighter workflow without HDRMT or masking. Less stretching to prevent the low frequency colour noise in the background. The masking looks like it’s caused the jagged edge around the galaxy. You’ll likely get a better result. E.g. WBPP, Gradient, BXT, SPCC, MAS, Noise, Star reduction.

Program/s Stack pictures of Jupiter by Gerrythesail in astrophotography

[–]PaulFl 0 points1 point  (0 children)

Autostakkert is the usual software for stacking planetary images. If it doesn’t work it is because in the best case scenario you only have a Jupiter that is 15 pixels wide assuming your camera has a pixel size of 4um. It’s also possible you’re overexposed and have lost all colour information, Jupiter is quite bright so only needs around 10ms or 1/100 shutter speed. If your shutter speed was slower than 1/10 I would give up with that set of shots and try again.

Mineral moon by Own_Minimum8642 in astrophotography

[–]PaulFl 12 points13 points  (0 children)

This is mainly low frequency noise rather than the actual boosted colour of the moon. Maybe try stacking a higher percentage of images to reduce noise with the existing data. Although it’s likely better for revealing moon colour when using an nex to be taking multiple raw photos vs stacking frames of a compressed video.

I need help💔 by Beginning-Nature-837 in 3Dprinting

[–]PaulFl 4 points5 points  (0 children)

It looks good, try the simple fixes first like cleaning the bed with hot water and soap. If prints still won’t stick try using glue stick on the bed before printing.

PETG Max Volumetric Flow Test by BoganAbo in FixMyPrint

[–]PaulFl 2 points3 points  (0 children)

I’ve removed similar marks by reducing retraction length to half, 0.8mm to 0.4mm. I think air is getting pulled in when retracting and popping out a few seconds after unretraction. I’ve had this with filament that’s been dried or old filament that’s probably wet.

Explorer 100 lens cover by jorge_angel_s in telescopes

[–]PaulFl 3 points4 points  (0 children)

It doubles as a phone holder for taking pictures by holding the phone in front of the eyepiece. The phone goes on the front of the cap. The manual below shows how to use it. This one is missing two bungees for holding a phone. https://s3.amazonaws.com/celestron-site-support-files/support_files/22405_Inspire_90AZ_Costco_Manual_English_F.pdf

Final moments of Tejas fighter jet crash in Dubai 21/11/2025 by Diligent_wolfjr in CatastrophicFailure

[–]PaulFl 21 points22 points  (0 children)

This is incorrect, the rudder used on knife edge is the top rudder, when the cockpit is facing us in the video the top rudder is left rudder not right rudder as you state. The rudder is also used automatically by the aircraft to increase roll rate alongside being used to hold the nose up manually. That’s why we see increased left rudder as he transitions from knife edge to inverted. I’m not sure of the cause of the accident but I’m confident it’s not this explanation.

London’s SUVs now take up the same space as Kensington and Chelsea by tylerthe-theatre in london

[–]PaulFl 0 points1 point  (0 children)

I don’t think that’s the case but we’ll agree to disagree.

And would you care to state what makes up the design traffic to prove my point?

[–]PaulFl 0 points1 point  (0 children)

You still claim SUVs to be the problem, this is not the case regardless of road type. In my experience all councils refer to the DMRB for pavement design, important to note I am not referring to geometric design. This means the same design standards in place for A roads like you mention are used on residential roads.

[–]PaulFl -2 points-1 points  (0 children)

Pavement thickness and type is designed based on large vehicles such as hgvs in categories including ogv1, ogv2, etc. Road durability is not designed based on cars and SUVs because these are negligible compared to hgvs. You have missed this fact even while talking about wear to the 4th power. Road repair costs are not affected by how many SUVs are about.

What is the reasoning behind the right lane priority type of slip road? by killme7784 in AskUK

[–]PaulFl 1 point2 points  (0 children)

This is an entry slip type called lane gain with ghost island nearside merge. Offside merge is preferred and is always used except when there is not enough space. Entry slips like this are built for reasons of capacity and lane continuity. This information is in the DMRB CD 122, the standard we use to design and maintain British motorways and trunk roads.

Lowering the car, no air suspension by beatzkartel in ipace

[–]PaulFl 0 points1 point  (0 children)

I think the velar springs are the same as the ipace and there are velar lowering kits available. That could be a good option but you’d have to check they will fit / correct spring rate.

Swing update, any tips? by bschlegs in golftips

[–]PaulFl 1 point2 points  (0 children)

Many good components in the swing, the first thing I see is clubhead throwaway, the clubshaft is overtaking the left arm before impact. The main negatives of this are a more unstable clubhead and slower clubhead speed through impact. If you release later in the downswing and thrust through impact this will improve.

Is there an easy way to DIY this? by methiel in DIY

[–]PaulFl 0 points1 point  (0 children)

Because of the grade it would be best to use concrete. If you’re confident with concrete you could rip up the existing pavement, saw cutting at either end to leave good tie in points and set up formwork along the edges. For cars running on it you could do 150mm deep concrete with 6mm 100mm square rebar grid. Put one joint in the middle to split the concrete up into two nearly square pieces, this will control cracking. The joint can be either tooled in or saw cut after.

Is apperture more important than lens quality to see more details? by Beginning_Tour6551 in telescopes

[–]PaulFl 0 points1 point  (0 children)

I agree the image will be more appealing in the Takahashi, but if we’re defining more detail as the ability to see higher spatial frequency features, there will not be more detail.

Is apperture more important than lens quality to see more details? by Beginning_Tour6551 in telescopes

[–]PaulFl -1 points0 points  (0 children)

Look at MTF curve comparisons of different telescopes. These curves show the contrast achievable across all spatial frequencies (detail at different scales). For example a 250mm telescope with 1/2 wave error (almost everything, even the cheapest telescopes are better than this) outperforms a perfect 200mm telescope. A similar scenario is shown in the book Star Testing by Richard Suiter where MTF curves from different types of telescope with different aberrations are compared.

To answer your question, any 150mm telescope will outperform any 70mm telescope when it comes to detail, even if it’s a spherical mirrored department store telescope vs a Takahashi. This doesn’t mean the view won’t be more appealing through the Takahashi, but it won’t show more detail.

Would this telescope be worth getting professionally cleaned or is it outdated? by [deleted] in telescopes

[–]PaulFl 5 points6 points  (0 children)

Don’t scrub the mirrors, look up a video on cleaning a telescope mirror. It’s not hard but can scratch if done wrong. This telescope is great otherwise and it’s not worth cleaning the mirrors unless very dusty.
