What does space look like through binoculars?
RT65CB-SWL replied to rorymultistorey's topic in Getting Started With Observing
Before anyone says anything... I don't have a hobby of looking at brickwork with binoculars. (first image). -
Hi @Space_Cadet and welcome to SGL. Definitely Venus, (with 'lens flare'). Yesterday, (24th March), Venus was at greatest elongation, as viewed from Earth. Mars, Jupiter & Saturn are currently in the morning skies. Today, (25th March), is New Moon. Enjoy.

What does space look like through binoculars?
RT65CB-SWL replied to rorymultistorey's topic in Getting Started With Observing
Great video. I always use my binoculars, (7x50's or 20x80's), and camera tripod + joystick head when travelling light or whilst my 'scopes cooling down. left: 7x50 - right: 20x80 -
I am assuming that you have a 1:10 Crayford focusser on your tube? With a Crayford focusser there are two allen bolts/machine screws on the underside. One locks it in position and the other one makes the drawtube/eyepiece holder slide in/out. I cannot remember which one, does what... doh! - I have attached 'Adjusting the Skywatcher Focusser' by SGL'er @Lowjiber The two knobs on oneside are... coarse focus, (large one/same diameter as the one on the otherside), and fine focus, (small one).

Eyepieces for a SW 250 dob
RT65CB-SWL replied to CLOUD90's topic in Getting Started Equipment Help and Advice
Hi @CLOUD90 and welcome to SGL. +1 for the TeleVue Radian, (now discontinued and superceded by the DeLite's), I have the 6mm. Radian's have 60deg AFOV, (DeLite’s have 62deg AFOV). Nagler's are nice too at 82deg AFOV. They are a bit more expensive than Radian's or DeLite's. If you want to go for a zoom e/p, then these. First off is the Nagler 3-6mm zoom, though it only gives 50deg; and then there is the Baader 8-24mm Mk llI or MkIV Zoom gives 68deg AFOV and can be used in 1.25" or 2" drawtubes. The earlier Mkl & Mkll zooms were fairly heavy. Pssst! - want a budget zoom e/p? ...the Seben 8-24mm, (not to be confused with its 7-21mm sibling)... apparently it is very good... unlike other Seben 'scopes & e/p's, (which is pretty much crap/$#!t). -
I have a Thousand Oaks glass type 2 and it gives a nice orange disc. It is showing its age now by showing very small pinpricks. They can be, according to Thousand Oaks be ‘patched up’ with a BLACK permenant marker pen. I spoke to a member of my local astro society and was advised to bin it, as it is not worth the risk damaging your eyes or those of someone else. Going with the Baader Solar Safty Film will be the cheaper option and just as safe. REMEMBER to check for pinpricks, tears, other defects before each and every use. BTW - I only view the Sun with a Herschel/Solar Wedge with the Baader Solar Continuum & single Polarising filters and a 70mm refractor.

Thank you for the kind comments @Sunshine. I sold the Vixen GP a few months ago, due to the fact it was getting very little use then my Tele-Optic Giro & AyoAOK alt-az mounts. Also, it was at its maximum payload with those two ...and yes I do miss it. I used to soak the legs with a liquid beeswax polish two or three times a year and the polish/buff off the excess and polish once a month with a solid beeswax polish.

Which constellations to learn?
RT65CB-SWL replied to PatrickO's topic in Getting Started With Observing
Ensure one of the gardens is facing south, (this is where the objects are highest at midnight). My personal preference would be the back garden, for your own safety and security. -
I use a shoulder strap that I salvaged from an old laptop/messenger bag, (plus two split-rings), with my 20x80’s - I have used wide camera straps for other binoculars that I have owned in the past.

Which constellations to learn?
RT65CB-SWL replied to PatrickO's topic in Getting Started With Observing
For the winter months my number one choice is and will be Orion. As for the remaining 9 or 11 (or more) important constellations, then I will have to pass, as I mainly view solar (white light), lunar & planets. -
Good to see you are enjoying your new 'scope. Just wait 'til you see Jupiter and Saturn with it... 😜

How do you turn a fork mount into a dovetail mount?
RT65CB-SWL replied to daslolo's topic in Discussions - Mounts
Hi @daslolo and a late welcome to SGL. Have you seen/watched this? ---> It is presented by 'uncle' Rod Mollise... 'The Godfather' of SCT projects & mods. -
Attenuate the bightness and show some cloud detail in larger instruments; i.e. 6 inches or greater.

Add a UHC or O-lll filter for M42 and a #47 (violet) or variable polarising filter for Venus and enjoy.

How to identify a passing object in our night sky?

Hi @Skyline_UK and welcome to SGL. A site worth checking out is: https://www.heavens-above.com/ -
Am I to remove the end caps? - It does not mention this in the manual...!

Colour filters will not work for visual of DSO's. The human eye has not evolved for low-light vision. The Andromeda Galaxy [M31] & Ring Nebula [M57], (and other 'fuzzy' DSO's), appear as fifty shades of grey visually For imaging you will/may need dedicated astro-imaging/astro-photography LRGB or RGB filters to bring out the colours. Other filters you may need are: Infra Red, H-alpha, O-lll, S-ll, UHC, to enhance detail/structure. Please feel free to amend/correct/comment if I am incorrect.

I sold my Vixen GP to a non-SGL person, and he said the same... "virtually zero backlash in both axes." - he is/was using an EQ3/2 as well. The only reasons for selling was... it was at the max-payload capacity with a C6/SCT & my 're-modded' ETX105 side-by-side. cannot be bothered with the faffing about with north alignment, polar alignment, etc., after spending a day at work, and then start observing. Perhaps one day I will regret selling it... truth is... I already do! - I was sorry to see it go. @AdeKing I am sure you will love it, as much as I did mine.

Hi @Joecobbs and welcome to SGL. As per @joe aguiar has said. They are 'defraction spikes'. I don't mind seeing them on star clusters, i.e. Pleiades [M45] in Taurus [Tau], but for planets it's a "No!" from me... and I do not have a Newtonian/Dobsonian/other reflector; that has the tube open to the elements on one end.

The only colour filter I use is a #47 (violet)... for viewing Venus. I don't go for the other colour ones. I think it is hype to boost profits rather than visual... I maybe wrong... 😜 Other than that, I use a polarising filter or the Baader Contrast & Neodymium and/or the Explore Scientific CLS, UHC, Olll filters... 🧐
