Alien 13

I am not a newt fan but I do like the Tal what a little beauty, it reminds me of a little military sighting scope I had with a one inch objective it gave stunning views.

My gut feeling is that Canon may have tweaked the HA response on models post 60Da my 650D certainly has no problem but the downside is getting optics lens/scope that can bring HA and RGB into focus at the same time.

Alan

It is a great Idea the issues with scopes like is that it could take several weeks before it gets 1st light and even then a smaller sensor might not show any significant errors straight away, the knowledge that the scope is A1 from the start is well worth any small fee.

I do think the sticker/certificate is also a good idea and would certainly add value later on if it was sold so the extra up front would pay for itself.

Alan

You could stick an astro logo on them and make a fortune......must get down to the local pound shop.

Alan

A sheet of plywood with rubber stuck on to it with a handle is called a table tennis bat.

Alan

The Canon lens can be used wide open if you use thirds focussing but it does give better results at F4 which is still faster than any APO I know of, the star 71 would probably out perform it though but is F4.9 ish.

Alan

As above one other big advantage of the canon is the ability to use Magic Lantern software.

Alan

My Seagul cost £22 I think, would be a great money maker for someone with a 3D printer.

Alan

I use one too and it pretty much solves all my problems even with my mount at its lowest position for imaging.

Alan

FLO will quote you.....

I want to try exo-planet imaging,  now where can I buy a Webb Space telescope for a fiver and a pack of hobnobs

There is this and although its not a Newt it would have to be Dob mounted if you wanted it on your patio http://www.firstlightoptics.com/clearance/hubble-cassegrain-reflector-telescope.html

Alan

A few more from me, just to keep these Vespa, sorry I mean these Dob and Newt boys in check

Not mine of course, but thought it worth posting

What a great set of scopes, I would be happy with the finder from the last one and for once the images on the side of the box dont lie.

Alan

Lovely, I was begining to think the Maks where being left out.

Alan

Small but perfectly formed my ZS71.

Alan

Would Nitrogen be more expensive than Argon when Nitrogen forms the main bulk of Earths atmosphere?

Comercial Nitrogen comes in various grades and I do not know which type is used in eyepieces but the Oxygen Free variety is expensive.

Alan

To stack widefield images I used to use Dss or PI but recently I've been using PS with good results. Use the automate script to load the stack of images into one layered image, lock a reference image typically in the middle of the stack and then use the auto PS alignment. Convert the aligned stack to a smart object and then use the Median stack mode to blend all the layers together. The noise reduction in this method is surprisingly good without using darks

That sounds great but not exactly sure what you mean (i only have CS2 at the moment) any chance you could post more details at some time.

Thanks

Alan

Can I ask what this is? It kind of looks like a home-made one, but I can't tell.

And would something like this do the trick I wonder?

http://www.ebay.co.uk/itm/58mm-Collapsible-Rubber-Lens-Hood-For-Canon-Nikon-Sony-Camera-Photography-/281130508615?pt=UK_Photography_CameraLenses_Lens_caps_hoods_adaptors_ET&hash=item4174af2147

I'm trying to work out dimensions for a home-made dew shield cone, and it's already frying my brain.

That is similar to what i bought mine was a 72mm version with a 58-72mm step up ring but the one shown looks ideal and rubber helps with insulation.

Alan

The diameter needs to be quite large to avoid vignetting i use this on my kit lens and the 50mm lens.

Alan

I dont know how the HEQ5 differs but on the EQ3/5 the RA setting circle is designed to introduce a lot of drag and unlocking it allows the RA axis to swing free.

Alan

I want one!

Alan

OMG

Alan

As a non newt owner i am very impressed it does seem the ideal balance between aperature and trackability wonderful stuff i must get one.

Alan

Streteched a bit much but here it is a bit brighter. 

Thats a cracking image i would be happy with that, you will find you will re use your subs as you learn more im still at that stage.

Alan

Guess I should open it in photoshop and stretch it.  Its a lil dim now.

Much better though the halo is gone.

Alan

And the halo is from me doing a gradient removal in photoshop not know how to do it but watching a quick video.  Its sort of cool, but it would be better if I had gotten rid of the halo.  Funny the halo didn't stand out until I posted it up.  Much more noticeable here then on my screen.  Strange.

I followed the gradient removal tutorial and could never get it to work so i did the 1st few steps then inverted it and used one of the standard blend modes.

Alan

Hi and welcome aboard i dont have any specific recomendations but have a look at this link most of the scopes listed have been recomended by SGL users http://www.firstlightoptics.com/beginner-telescopes.html
