Thanks for confirming that guys, that's what I thought too, but what about the photography? Will f/8 be equally good for imaging too? (Both when using SLR adapter and digital camera in stead of an eyepiece).

I am not able to answer you, I do not take photograph of the sky.

to take into consideration, the weight, the length.
the f8 is by far the best for planets.
the focus being longer, the light is therefore focused farther away, therefore less aberrations.

very nice capture .

superb shot .

My favorite nebula has to be, m42 .

very very nice image.

real lace, very pretty.

an image of very high quality.

superb photo, the details are exceptional, thanks.

very well done, thanks.

OK. Well you've obviously found the welcome forum, there are some stickies there, and I expect you've found other forums by activity area.
The "Activity" drop-down gives you access to several useful views and filters, such as threads that you have started and those that you have posted in. You can choose to follow individual posts and members, which will appear in standard views ("my activity streams"). You can even convert your own searches into bespoke "custom streams" that will appear in the same menu.
If you prefer push notification to passive checking, you can even turn these into RSS feeds, and include them in an external news reader.

If you're interested in buying second hand gear, you might want to keep a close eye on the For Sale/Swap section - there are sometimes good bargains, but they go very quickly.

thank you very much for all this information. It's very appreciated .

Hi, welcome.

Is that "figure out how this website works" or "figure out how astronomy works"?

Do you have any specific areas of interest?

Do you already have equipment?

hi, 

thank you ,
I'm trying to figure out the site, for astronomy it's not bad.
As for the equipment, I have a 102 ed and a 120 ed with Delos eyepieces.

I have an Optics UHC filter which is said to be great for nebulae, it did improve the contrast for me but I think it will depend on seeing conditions and the telescope as to by how much.  It's been quite a while since I used mine (mostly because I've been in the astro doldrums in recent years) but this year I'll definitely be giving it a go now that my interest in the hobby has returned.  Note that this filter will turn stars green, and from memory gives the nebula a faint greenish tint.  Definitely worth a go at the price.

Using a bigger aperture then an OIII works amazing on Orion however using a 120mm aperture I would say a UHC would serve you better.

The astronomik from FLO have a nice tight tight bandpass across the relevant frequencies although the much less expensive Explore Scientific are not a million miles behind it if your on a budget.

I personally found an Ultra High Contrast filter was best on M42, I have used it in most of my scopes but now do not have one as I tend to use scopes for photography over visual.

Alan

is there a difference with the uhc and uhc third generation of lumicon?

and thank you for your response.

Hi all ,

I am trying to find out which filter would be better to watch m42, sw telescope 120 mm ed.
Thanks in advance .

Hi all ,

which constellation fascinates you the most and why ?

for me .

summer = the Sagittarius and the scorpion, jewels so hidden in the surroundings.

autumn= Cassiopeia and Perseus  .

winter = Orion the master of all hunters .

spring = I haven't found it yet.

AND YOU ?

good evening to all of you .
I'm new to this site and trying to figure out how it all works.
I look forward to talking to you.
