Falak-Online Komuniti

petang tadi, tah camne terbeli :shock:   fork mount etx125 dari sorang member, Tommy (gambar no. 25 dalam galeri konvensyen USM ), hehehe..

sebenarnya memang tgh nak cari mount GoTo yg beli fitkan kamera Mintron dan lens 135mm . Kecik sikit dan mudah nak bawak sana sini. Tak nak beli ETX yang lengkap pasal tak akan gunakan pun teropong dia... membazir pulak.

Alhamdulillah rezeki dtg bergolek bila Tommy kata dia nak jual mount tu.

Sekarang tengah dok fikir macamana nak buat mounting yang paling mudah letakkan mintron/lens tu.

Cuba tengok gambar-gambar di bawah

Mounting sebelah kanan fork tu sahaja yang ada motor. Yang sebelah kiri setakat memegang je. Tengok gambar mounting kanan tu, spt di bawah
(http://falak-online.net/DataInfo/studyetx/DSC01365.gif)


Kemudian cadangnya nak buat some sort of platform antara 2 side tu, dan letakkan mintron/lens tu atas platform tu. Position lebih kurang macam gambar-gambar di bawah...

Sesiapa yang ada idea camne nak menrealisasikan impian di atas menggunakan barang-barang yang mudah didapati di kedai-kedai?

 :?:

hi shah,

boleh juga kalau you pergi shopping dekat Ace hardware,Ikano Power. cubalah nasib....mana tau boleh dapat sikit idea.....Biasanya saya akan buat begitu. Itulah sebabnya saya dapat fikir berbagai-bagai jenis modification.

Tommy

Tommy,

 :D  you masuk juga dlm forum saya ni.. hehe.. tnx.. memang cadangnya nak ke ikano petang semalam, tapi ada kerja lain pulak... selain ikano, teringin nak tengok handymart di sek 14 pj tu, adalah bbrpa option.

handimart tak banyak barang jual....semakin buruk....
Janganlah buang masa kat handimart. Pergilar ace hardware tu.

Tommy

Peh! Shah pun dah ada ETX! Nanti boleh buat kelab.
Entahla saya pun takde idea lagi selagi tak dapat tengok depan mata macam mana nak hack mount ETX tu.
Kena betul2 kuat  untuk support lens+camera tu.
Kalau ada scope boleh piggy back jek camera tu atas scope .. cuba cari kat weasner punya website..
Saya memang suka pi ACE HW kat sebelah IKEA tu.. rasanya the best hardware shop in Malaysia.. 2nd choice would be HomeFIX kat block baru 1-utama.

Baru jek order ETX saya la ni dah berangan nak beli Zenithstar 62m Semi-apo piggy back atas ETX.. hehe..
Then  dah dapat barrel 1.25" dari Grandeye nanti nak kena beli ToUcam kat lowyatt lah pulak..Then kena beli Barlow lagi..eyepieces lagi.. Aduss...
boleh bankrupt :)


kamayok3,
Wow! Sekarang guna Vixen mount ke? How much did u buy? From where?
How was it ?

hi rizal,

kalau u nak piggyback zenithstar kat atas etx....you need counterweight to balance it...I got the peta to make the counterweight set...Will share with you all if interested.

The vixen SP mount is a stable mount that i have ever seen. I like it very much.

Tommy

Bukan complete set ETX, cuma mount dia jer... OTA ETX tu Tommy dah guna dgn mount Vixennya.

Lunch tadi pergi ke ACE hardware di Megamall, a bit smaller than Ikano kot, adalah nampak few things yang possible untuk add-on pada mount etx tu. Homefix belum try..tak tau pun kewujudannya! floor mana?

Tommy-> Handymart tu nampak macam nak bankrupt je!? Dulu kira ok lah, tapi lama-lama makin tak menarik...  :roll:



Sabar bro, sabar!!   :lol:

yah.....handimart tu dah nak bankrupt mungkin. Jadi, Macam? Saya sedang look for f/6.3 focal reducer...ada siapa nak jual? Tadi baru order a 2" SCT crayford forcuser dari si Jason, budak kelang tu.. The price still quite reasonable la....murah daripada William Optics one... but same quality with it.

Lets see the quality next week.

Tommy

kamayok3,
Counterweight like this?
(http://www.p-price.dircon.co.uk/Images/dscn0245.jpg)
Do share the diagram nanti... many thanks!
Ada tengok dekat stargazer.com.my the zenithstar is selling at rm1k+ so boleh replace my finderscope lah agaknya :)
Itupun kalau ekonomi (+isteri!) mengizinkan :)

shah,
Rugi jek GOTO-mount tu jadi letak kamera .. apa kata beli satu  scope pasang kat GOTO tu.. letak atas tower mount pasang permanently kat taman atau atas bumbung rumah.. sambungkan kamera+GOTO cable ke PC.
Boleh jadi observatory .. monitor pakai PC kat rumah hehe :)

yeah...betul...saya ada satu tukang besi kat ipoh...dialah yang tolong saya buat...saya kasih dia tu diagram....dia pun modified sikit untuk saya. very nice result.
can i have ur email? send the photo to u now...

Tommy

thanks kamayok3
email
arafip at yahoo.com :)

saya cadangkan, beli telrad atau rigel star dot finder, lagi berbaloi. Harga area 100-200 je. So duit lebih boleh bajet beli accesories lain. Berdasarkan pengalaman saya, finderscope jarang berguna. In fact finderscope yang atas LX90 saya tu guna untuk alignment sahaja, lepas tu terus depend on autostar.

GOTO-mount tu, tujuannya untuk jadi travelscope saya. Ada tengah buat plan jangka panjang untuk rakam kesemua deep-sky object dalam Sky Atlas 2000.0 .... kononnye ler... tu lah sebab nak cari option yang mobile sikit.

Kalau buat permenant observatory di rumah (sri damansara) rugi, pasal langit memang teruk light polluted. I prefer to be a "mobile stargazer"  

 :wink:

Wah caya la hangpa semua. Aktif!

Rizal dah nak beli APO plak? Wah rizal jeles aku dengar ehehehe...
Tapi beli APO ni memang berbaloi kalau nak buat astrophotography, betui tak shah? Ada browse kat singastro aritu tengok depa buat astophotography guna APO (TMB, Megrez, Pentax) 80mm jeh tapi imej depa mengancam!

Rizal kat singastro ada 2nd hand nak jual Orion 80ED Apochromatic Refractor dalam SGD950.00 Dari bacaan review APO Orion nih kira low cost tapi kualiti optics cantik jugak.
Stargazer jual Megrez 80 ll F/7 ED triplet APO harga RM4100.00 with 3% discount! Yummy!  :P

Piggyback APO kat atas ETX (nanti APO lagik besar dari ETX ehehehe) ETX untuk visualnyer, APO untuk astrophotography nyer. Mengancam!

Tapi yang tak tahan harga pun mengancam. :(

botok,
APO tu berangan jek .. kalau dapat bonus boleh la beli --  :)
Adus tensionnya.. baru dapat mesej ni dari Grandeye .



Tapi appreciate the kindness of the vendor willing to check condition scope tu..sebab ada kes kat Singastro dapat scope tapi ada problem.. so saya cakap kat dia mintak check kan the GOTO really works before sending.

Yang kecewanya.. CNY ni tak dapat la  "skodeng" SATURN  :(

rizal,

Saya ada satu mount MEADE #887 advanced field tripod with equatorial wedge nak jual la. Tripod ini sudahpun modified boleh turun ke tahap 0 degrees. Bro Shah pun sudah nampak mount saya itu. Saya gunakannya untuk ambil gambar dan visual saja. I prefer equatorial photography style.

Mount ini boleh guna kat atas ETX series dan LX90. Masih nampak baru lagi. Belum sampai 1 tahun pun. Sebab saya sudah jual fork mount tu kasih bro shah, itular sebab saya tak guna lagi. Harga mount yang baru adalah USD360.00 without adding shipping fees....tapi saya nak jual kat RM900.00-RM1000.00 (negotiable price). Urgent nak sell out.....

info online ia.... http://www.meade.com/manuals/TelescopeManuals/Tripods_and_tripodaccessories/ETX_to_%20LX_%20Mount.pdf

kalau you nak more info and gambar mount tu, email lar saya... tommylim@emcs.com.my

Tommy

Tommy, yang u ada tu advance field tripod sahaja atau datang sekali ngan goto mount for ETX?

Saya ada mount saja...tak ada GOTO mount.......GOTO fork mount tu sudah jual bagi bro Shah...

Jadi, yang mount saja saya nak jual.

Tommy

kamayok3,
You punya offer comes 2 minutes too late.
Saya punya order ETX tu comes with deluxe tripod so biar lah dullu saya kena tengok kualitinya dulu sesuai tak dengan scope punya weight.
Ada aksesori lain nak jual?
 :)

deluxe tripod tu tak boleh turun ke 0 degrees. Saya ada kawan nak try to modified the delxe tripod, tapi nampak the whole fork mount nak jatuh...tak tahan lama. But this equatorial wedge is really for this purpose.

Do you know ETX in Alt-az mode cannot do long time exposure? Do you know what is the reason you need equtorial wedge?

Tommy

Last time when i ordered ETX125 set.....I straight away ordered the MEADE #887 advanced field tripod. Then I cancelled off the deluxe field tripod.


Hope u faham la:)

Tommy

kamayok3,
Thanks for the tips. Let me have a look at it first  - I am such a beginner so before buying more ( i have a long list of accesories ! - tadi baru berangan nak beli burgress Binoviewer USD199 pulak!)  I will consider your tripod too - let me check if I can cancel the deluxe tripod from Grandeye.

Actually for ETX....As a ex-ETx user,Let me give u some tips...

Normally becoz of the focal length of the ETX....so, a lot of accessories we cant use it perfectly. It is wasting money if u buy a lot of stuffs...but cannot give you good satisfication. Normally I check all the spec of products before i buy things.

So, The balancing of the tube is also important. I heard that you buy a binoviewer. For ETX....binoviewer is too much heavy for the tube. So, better think of a good balancing system for your ETX though:) I experience that before.....hehe

Advice: Always think of the focal length before you buy ep and anything regarding to viewing or photoraphing.

Tommy

will wait for your decision on buying the mount from me......

Hope can get if off soon. :)

Tommy

If got time, whole falak-online members can have a drink anywhere.

We can meet up and discuss about telescope, events....and so on..

What do you all think?

Tommy

Tommy,

Good idea, tapi yang kalau ikut posting ni, macam 4 orang je ada area KL. Yang lain camne?

BTW, why not u take gambar foto mount tu and post it in here. It's perfectly legal..  :twisted:

Untuk semua,
Saya dalam final stage untuk buat modification bagi mounting ETX tu. InsyaAllah hari ni or esok siap. Then I akan ambik gambar untuk komen. Plannya minggu depan balik cuti kat Besut, boleh try out. Botok, balik kampung tak minggu depan?

shah,

i will email all the photo to you...then u upload for me,can?

Tommy

OK Tommy, here are your photos, I dah upload....take it from here..

Thanks shah.....

Rizal.....now u can have a look on it. Good ot not?:)

Look like still new....I only done some simple modification on it.

Consider about it.

Tommy

This is my ex-setup  :D

Have a nice reference...

Tommy

OK grandeye willing to accept my proposal for the deluxe tripod at hkd800.
How much are you selling ..give me good discount lah.. But can i pay half first.. quite broke this month laa :)

okok.....how about if I sell it to you at RM900.00?

This is becoz this mount is quite expensive and the shipping fees are much more higher due to the weight of package. I believe RM900.00 is a reasonable price for it. Hope you can understand.

Hope you can confirm it after next week..... Coz i wont be in KL for a week. Balik kampong lo.....Sabah!!! Hope can get 13 hours new moon from there.

You have to look at it first.......we can set a day,time and place then meet up.
Ask bro Shah come over together as well la....then we can discuss some other project then......

Tommy

OK in that case .. see you  next week lah. Hope we can have a drink soon around KL.
And have a nice Chinese New Year!

OK in that case .. see you  after CNY. Hope we can have a drink soon around KL.
And have a nice Chinese New Year!

Good idea tommy, bleh la kuar minum-minum sambil discuss-discuss. Nanti don't forget to inform me kalau korang nak gath mana2 itupun kalau saya ada kat KL at that time.

Shah tak jadi balik tapi mmg plan nak balik tapi kereta just broke down semalam, gasket bocor. Dah la citroen nak cari sparepart susah dahtu nak CNY plak nih.... adusss fenin! :P

Anyway happy CNY kepada sesiapa yang sambut! :)

Bah...boleh lar! Kita akan jumpa after this long holidays.

Rizal....you tinggal kat mana? Saya tinggal kat SEAPARK,PJ.

Handphone no. saya 016-223 0048.......bolehlar sms saya ataupun call saya bila bila masa after holidays.

Kalau ada apa apa....post lar message kat forum ni....saya ada bawa notebook balik sabah. Boleh chat dengan you orang jua.

See ya

Tommy

Orait!
Saya dok kat area Subang airport.. near Subang Bestari and Subang 2.
Nusa Subang to be exact.
So see you soon!
:)

ok Rizal....maybe you can ask shah to come to my house on saturday morning.
Bro shah knows where yo wait for me one.:)

Then I can show you my latest setup and also the condition of the mount.

I also want to see the last stage of modification for Bro shah mintron video camera bracket into the ETX fork mount.  :twisted:

Boleh tak? Bro shah.......

Tommy

Boleh je Tommy, rizal, botok. We can find a good spot for technical how-to discussion on telescope and stufff. Tak menjadi masalah. Just set the date. Tapi saya balik bercuti dari Selasa until Sabtu. Jadi kalau nak buat mungkin b4 atau after.

BTW, my modified ETX-mount has completed!  :D   It seems ok so far. Lepas ni kena buat some make-up sikit, bagi lawa. I'll post the photo esok... jeng jeng...

lagi satu, anyone knows di mana boleh beli good quality 2nd hand camera lense? Preferably yang ada c-mount.

cubalar cari kat sini.

http://www.mir.com.my/rb/photography/ftz/index.php3

Saya akan balik kampong besok sampailah hari ahad minggu depan. Jadi, kalau nak jumpa, tunggulah saya yeh.....

Tak sempat lagi nak tengok modification Shah tu...

Tommy

Wah cantik shah! Bertukang sendiri ker? :)

Pasal 2nd hand camera lens. Saya tak tau kualiti ok ker tidak tapi arituh ada pergi "cash converters" dekat ampang point tepi habib jewels tuh. section camera dia banyak ada jual lens2 slr 2nd hand dan murah2 plak tuh.. price ranging from rm 40-200. From the looks of the condition nampak cam cantik lagik! Dah tu camera SLR lama2 pun jual murah2. Boleh la try tengok.. :)

Ada satu lagi cash converters dekat TMN SEA PJ.

hmmm.. kalau saya bertukang sendiri, dah lama siap truss tube dobsonian idaman tu..  :lol:    adik ipar yang tolong buat tu....

bab kamera lense ni, nak tanya sikit lah, selalunya dia akan tulis , contohlah, 50mm f/1.8.  Jadi 50mm tu aperture lense atau focal lenght? Kalau pada teleskop, selalunya ia akan sebut aperture dulu... kalau kamera lense, camne yek?

tough yeah.....nice design and outlook.

This is what we call amateur astronomer.:)
Weather in sabah very nice....Can see M42 terang terang.

Sayang tak bawa balik scope..... :(

shah...let me answer ur question......for an example, the 50mm F1.2 means

- A 50mm lens produces an image of a distant object on the film that
is the same size as would be produced by a pinhole 50mm from the film.
 
- The F1.2 means aperture of the lens.

Do you understand?

So, when are u goin to test out ur new design?:twisted:
