Nicely digs out features plus atmpsheric stuff. They are hard to find though.

So far, I've been vastly underwhelmed by the result every time I've tried them, and find the annoyance of any false color induced to hugely outweigh any minuscule gains of detail from the filter. My experience as well. Post Extras:       great lesson sage Reged: 04/04/10 Loc: Canada Re: Just a Poll: who observes planets with filters?

I find if I use filters to observe the planets I get false colour and the image is just too dark.

[Re: great lesson]       #5029389 - 01/20/12 08:22 PM Edit   Reply   Quote Quick Reply   I have tried a couple filters but have not liked the view through them. As Mars gets bigger and is up at a more reasonable time I will experiment more. Recently though I have used a variable polarizing filter on Venus to bring down the brightness. Without the VPF Venus is a giant bright disc. With the VPF on close to the least light let through, I have seen Venus as a more detailed Gibbous sphere. I was happy because I finally found a use for my VPF! Post Extras:       azure1961p Postmaster Reged: 01/17/09 Loc: USA Re: Just a Poll: who observes planets with filters?

Now wouldnt that be an item. I have a feeling sonar of the future will bw so good itll identify fish species or classes by signature. Not tomorrow but... Off to smell my filters.

After doing a star test on some other "big" names, I wouldn't use very many else. A few have mentioned he pale blue 80 and the Salmon for Jupiter. Salmon is also good for Saturn (BTW- Rings are looking nice again) I'll frequently thread the filter in the diagonal if it's night where I'm chasing the seeing. And yes, I've switched from Planets to DSOs and wondered what happened to the view before Post Extras:       azure1961p Postmaster Reged: 01/17/09 Loc: USA Re: Just a Poll: who observes planets with filters? [Re: dyslexic nam]       #5029644 - 01/20/12 11:13 PM Edit   Reply   Quote Quick Reply   Ive never had a bad filter, save for a damaged one I received once. Both Orion and OPT are essentialy opticaly invisible save for the filter effects. Frankly, and despite manufacturer claims to the contrary, all wrattens are the same. Sure a bad one sooner or later is inevitable, but they all are utterly transparent. Now if a filter is tightened too much in its cell it can cause astigmatism. But really, and Baader claims aside, my Celestrons, OPTs, Orions and Lumicons all are terrific. Deepskt filters probably have more going on in terms of one brand having a different band pass than another. But Wrattens? No differences aside from manufacturer claims and lens cell design.

[Re: CowHampshire]       #5032376 - 01/22/12 02:45 PM Edit   Reply   Quote Quick Reply   FWIW, I've gone through phases where filters seem to help, seem to do nothing, seem to actually be worse than with no filters at all. The filter set I've found essential at times has sometimes disappointed to the extent that I've started to sell them off. Then later, I'll find it starts to be useful again. This over decades. So my take on this is that with astro gear, it is easy to become "conclusitory" over subjective details. Because they don't provide enough consistency in results. Having sold before and then reacquired later, I've come to realize that its better to just wait and occasionally experiment with such gear. So why is this so? I don't find that this is the case on the photographic side - filters seem to be consistent in that usage. I think its due to eye / sky variations that work or don't work with the combination. As my eyes have aged, variation seems to have increased, as if the S/N ratio decreasing means that the specific combination, whatever it is at the given time, becomes critical to perception. It could be that patience with the equipment is as valuable to the process as the equipment itself. This is not an age for the encouragement of patience. Oh, and in general, the greater the CO and lesser the exit pupil, the less that filters see to do on the average. Hope this helps.

[Re: wfj]       #5034278 - 01/23/12 05:12 PM Edit   Reply   Quote Quick Reply   I use a filter wheel with #8, #58, #15 and Semi-Apo filters. Jupiter and Saturn "pop" with a #8. Mars is much more contrasty with the Semi-Apo with seemingly little if any light loss. I use the clear port if I want to view the natural color but sometimes the Atmospheric Dispersion becomes a nuisance. I can barely see the CA tho'.....it is just that tight right underneath the AD. It is true that you can "see" just as much without a filter but the filter makes it easier to see without trying so hard....much easier.

[Re: Asbytec]       #5034384 - 01/23/12 06:21 PM Edit   Reply   Quote Quick Reply   I have tried to use filters many, many times and I don't think that I have ever seen any feature with a filter that is not seen without the filters. There are some that do seem to enhance color, but I don't find that translating to seeing features I can't see in the first place. I am a bit OCD, so I am sure I will get them all out and try them again, but I doubt there will be any screams of "Eureka!"

Deepsky filters on various nebula actually do this often but in the lunar/planetary realm its more about enhancing whats already seen which extends comfort and visual acuity. In poor seeing it can surpress the unwanted atmodpheric scattering and in some cases can actuallu help to isolate a given feature, ie; martian hazes. Revealing otherwise invisible details on the planets - never seen it. Enhancement though, for me its an utter certainty. I dont fall out of favor with it from one year to the next, wrattens are ALWAYS my oculars best friends. Been that way for decades.

It's true with scopes too. So you have to "lose" the reference image/memory before a valid sample occurs again. But then, conditions may have changed. I just try combinations likely to work given past experience til one works. Usually, I lock on to that one that consistently works and stick with that for the session. Don't find switching around to help. Post Extras:       cheapersleeper Carpal Tunnel Reged: 01/22/10 Loc: Sachse TX Re: Just a Poll: who observes planets with filters?

Pete Pete, If this is the case, then I think I would opt for keeping the natural color of the planet being observed.

Would be interesting for someone who test on the same color... best vs cheap and we might find out whats the result. I think it is not much different because of its just glass but coating and quality might be big different ..... not sure! Post Extras:       t.r.

I find it helps with darker belts, bands, and barges. It helps a little with the GRS too, some years more than others. That's about it for me. Post Extras:       Pages: 1 | 2 | 3 | 4 | (show all)
