One of the images you showed definitely had star halos. I guess it depends on each setup, and star brightness, as to whether they will be present or not.

[@AstroOnBudget]

Good observation! Yes it doesn't eliminate it 100%

[@tomreid7]

I thought this filter was for mono cameras only, but you've put me right on that, thanks, it's now on my list to buy.

[@AstroOnBudget]

Monos have advantage over RGBs but that doesn't mean DSLRs can't perform well :)

[@Svbony]

😍😍it's really nice video and filter ，thank you very much!

[@MissileGuidance]

Awesome, very useful video. If you don't mind me asking, what is the name of your accent, I love it 🔥

[@AstroOnBudget]

Haha. Well I live in Australia.

[@ollinevalainen8642]

Great! I have a Canon EOS 6D Mark Ii, which doesn't allow these clip in filters. However, is it possible to attach this kind of filters on a telelens?

[@AstroOnBudget]

What are you using 6D with? If with telescope, you can attach it very easily. If you are using lens then it can be hard.

[@ollinevalainen8642]

@@AstroOnBudget Using telelenses such as Canon 200mm f2.8 and Sigma 150-600mm.

[@AstroOnBudget]

@@ollinevalainen8642 that will be difficult without the clip in filter unfortunately. Sometimes you can get filters that mount on the lens like ND filters but they will probably be expensive.

Pretty cool 🔭

Photo of the nebula B33 or Horse's head what was the ISO and time per sub?

[@AstroOnBudget]

From memory, single sub was 300sec, overall 2 hrs i think.

How would you use 2 inch filters with a dslr? I have a 8 inch reflector Good content mate keep it up Love from Perth

[@AstroOnBudget]

Gday mate, Get 2" T ring.

[@saulontheroad9605]

Great video, I just order this filter from my local store and I wonder how good or bad works with an unmodified DSLR as the one you show in your video. Also by looking at you sample I guess Orion and rosetta whe taken with an astrocam and the horse head at the end was done with your rebel. Finally, can I have decents results using this filter with an unmodified DSRL ? thanks for sharing

[@dropstopandroll]

Sadly my 6D mk2 doesn’t support clip in filters and I cannot for the life of me find a 55mm lens filter for h alpha

[@AstroOnBudget]

:(

[@mashpotatomountainobserver3338]

How's that SV405 camera turning out?

[@AstroOnBudget]

It's on the way! Once it's here I will make a video on it :)

Thanks for the filter review - I had not considered this before, so it was a good review for me and I will be looking into this accessory. To follow-up on one of your comments in regards to the clip in filters for DSLR, I do have the Svbony CLS clip-in for my Canon 1200D. I like the filter very much and I can definitely see the difference in my images as I live in a Bortle class 8-9 area. But I have noticed that I have to be extra careful and handle the camera gently so as not to cause the filter to pop out of the camera with any sudden movements. I do wish it clipped in a little more tightly, but I have managed OK so far. That is my only complaint with the clip in. So if I wanted to change over from the clip-in to the style that screws onto my camera adapter, is there an advantage to the 2" versus the 1.25" ? When I started out, my first scope had a 1.25" size, so I based all my accessories off of that. I recently upgraded to the Astro-Tech 70ED doublet and by default, it has the 2" fitting, but also comes with the 1.25" adaptor and that is what I have been using. My question is: is there an advantage to converting my accessories over to the 2" size ? I would first need to change my DSLR adapter as it currently the Svbony version for the 1.25" fitting. Thanks for your input.

[@AstroOnBudget]

Hey Eric, Yes, it looks like the clip in filters aren't as snug as they should be. Apart from that, how has CLS filter helped you? I'd love to hear about that. In terms of advantages of 2" vs 1.25", I think it all depends. Sometimes you get terrible vignetting because of using 1.25". Again, that really depends on your sensor size. 2" filter eliminates this risk of vignetting. But if you don't notice any vignetting, I'd suggest stay with 1.25". Moreover, If you ever want to upgrade to filter wheel, its better to stay 1.25" I think because 2" can add up in terms of cost as well as weight of the rig.

[@DrJ_MKE]

@@AstroOnBudget Thanks for the advice on the 2" vs 1.25" use... I have noticed some vignetting, but I've been able to crop it out during processing. So I will have to think about that when I go to order more accessories (field flattener, etc.). Yes, the cost difference is noticeable ! The use of the CLS in my light polluted skies has been very helpful. For me, when I've done the exact same number of light frames with the CLS filter and then compare to the same number of lights without a filter, the overall quality of the image (better detail) is noticeable after I run them the stacking software (Siril). And then the quality improves even more noticeable after processing. Keep in mind that I am not using a formal star tracker yet. Talk about working on a budget, I am using the motor drive that came with my original scope (Celestron PowerSeeker 80EQ) to be able to extend my exposure times: www.celestron.com/products/astromaster-powerseeker-motor-drive Using the Rule of 500 and/or the NPF rule, I should only be exposing for 0.5-1.2 seconds/frame without a start tracker. But when I use the motor drive, it allows me to increase my exposure time to 6-10 seconds... which is very helpful in capturing light/data compared to using only a stationary tripod. I have pre-ordered the Star Adventurer GTi for my first official start tracker mount, but it sounds like the back-order issue is going to force me to use my current set-up through the end of 2022 (?).

[@AstroOnBudget]

@@DrJ_MKE Wow thats awesome! You have my respect. Astrophotography with motor drive can be frustrating but sounds like you've got a system worked out. GTI sounds very promising. Both RA and Dec control would be game changing for portable setups. Have you dipped your toes in plate solving, guiding etc yet?

[@DrJ_MKE]

@@AstroOnBudget I have not ventured into those areas yet. Maybe once I get my GTi and I get comfortable with using a star tracker, then I will be able to consider those further enhancements.

[@AstroOnBudget]

@@DrJ_MKE Yeah there is no hurry. I am impressed that you have learnt astrophotography manually to begin with. That's so good and will help you know the fundamentals. Have you got any image that I can see :)?

[@hawghunters]

Can it be used for the sun?

[@AstroOnBudget]

No, this will burn in a matter of seconds. You need H -Alpha that is specially built for sun.

[@tommes9537]

Thank you vor this Video 👍

No worries ☺️
