  1. i have decided to get myself a SW Skyliner 200 dob. and at a later date when pockets allow find a good mount and use the 200 tube. i have one worry my hight, i am not very tall at 5ft. will i have any problems with a SL 200 mounted on a tripod ? also i notice no choice in focal length will this hinder me later when trying DSO ? thank you again for the advice.
  2. i did look at the dobs and the desktop one is a dob to, but i did not know you can fit them to other mounts. so i could get bigger mirror dob like the desktop one and mount it to a better mount later. only thing would be size and weight, there is only me to carry what i can by hand, laptop could be shoved into a backpack. thank your for the advice it is much needed.
  3. feel kind of let down, the advert says planets and deep sky objects. and then finding DSO is out of reach unless expensive mount used. i can push towards a SW 150 (black) with an EQ3-2 mount, it is a bigger mirror at 6" and double the size of my desktop scope. and i could save up for a better mount. but it would still not be good enough for DSO as it sounds. am looking to purchase one just after christmas, gives me enough time to research more on telescopes and mounts and what i really will be seeing as to what adverts say. so this means i am really stuck to planets and likes sadly i do not have transport to the astro clubs they are to far to walk to, so i tend to sit in the yard or shove the desktop scope on windowsill.
  4. I am looking to upgrade from a small 3" scope to a bigger sky-watcher type. i would like something that i can track with, so started looking at the sky-watcher 130 with an EQ2 mount, then i notice a 130P, and a 130PDS now i am getting a little confused, i pop to another site and they have a 130M. each scope has a different focal length some are 650mm, some are 900, some at 1200. all roughly in the same price range but i am confused from all the different types etc etc. i have around £250 GBP to spend on a new scope, and would like it to track (manual or powered). i found they tend to come on a eq2 mount so that is fine, but what focal length will i need ?. would like to capture the things i cannot see without a scope like nebula and likes using webcam/DSLR but also use eyepieces. thank you Tami
  5. i have the SW heritage 76. to be honest, i would not be hanging my canon 350D on the scope. it is not very stable with that high COG the camera adds. You would be better off mounting the camera to a tripod and going Afocal route. Afocal : using a camera mounted on a tripod and placed close to the scopes eyepiece. the camera will see what you see through the eyepiece fitted to scope. Primary focus : using a camera/webcam mounted direct to the scopes focuser. a good sturdy scope and focuser are best for this. a DSLR can cos more than the scope you are mounting it to. Pic 1 : this shot was taken from a 58 second video recording from a webcam, i used the heritage 76 and primary focus. Pic 2 : this shot was taken with my canon 90-300mm lens without the scope. Iso 200 - 1/125s exposure, auto WB @ f5.6 and 300mm. i would go a cheap webcam route with the heritage 76, and not risk a broken DSLR. As for planets i am able to see with a 10mm eyepiece jupiter and its moons using the SW 76 heritage
  6. started photography with a Olympus 3020 zoom and a sony DSC-P72, i then decided both should become IR filter less, and hacked them a part. now own a 350D (Cmos sensor ), i do get a little amp glow, but this could also be LP from local estate. Canon did a 350A, and removed the filtering factory side, had been trawling ebay for a while and when they come up they fly off the shelf. i think the main point factor for Canon was the eos capture software, the ability to use the camera's settings via a usb and pc, but also capture them straight to the computer.
  7. Yes i understand the table top scope is just for starters. i did own a tasco thing but was so let down by it at a younger age. i found the small 3' mirror good for the moon at primary focus, but getting the focus bang on was somewhat a hit and miss affair, a slight touch to the focuser would have picture way out of focus. i am looking to upgrade scope for a larger version, maybe a dobson, or goto type design, and then maybe upgrade the camera to 1080P type. something around the £250 price mark, i think i could get an 8' for about that price if i haggle with the store owner.
  8. will a barlow make my photographs more bigger ie: more mag without a webcam and using a 10mm eyepiece i am unable to get stars to pinpoint. and Googling has no hints on how to adjust mirror. i think it is glued into place so i cannot even adjust it forwards a half inch, and thus throw the focal plane out more
  9. scope used was a SW heritage 76 (76mm / 300mm @f3.9 )
  10. thank you everyone. i would love to hook up the canon to my SW heritage 76 dob, it should out do the canon tele lens. but i do not trust the small scope and cheap chipboard stand to carry the DSLR. taken a few more over the past couple days, but every shot (80+ raw frames) have a funny looking cloudy view ( sky was clear) so that session has been binned. the workflow is fairly simple, i have found registax complicated. CR2 into Tiff 16bit. import tiffs to RS, auto select alignpoints. align / Limit / stack. once i have stacked i mess with wavelets and do all. all settings in RS left at default.
  11. I came across a problem, when trying camera in telescope focuser. i would find the view blurred, and unable to focus in enough. if you are have this problem , not able to in focus enough with a webcam, you may wish to remove your eyepiece holder, and test camera you should find your telescope now allows camera to focus.
  12. for those that would like to see a couple images. i tend to take shots of wildlife and general stuff ( see attached) but i have taken to astronomy to, every lad wants to be a spaceman. i got halfway there playing online games, but the photography bug and that big bright moon was so tempting. so i leave you to view a couple of my photographs and a moon shoot from tonight.
  13. Took a couple of snaps with my canon 350D digital Kiss. slipped the canon EF 90-300 mm lens on. Sky was somewhat hit an miss. to the eye a cloudy halo around the moon. i am more at home shooting wildlife and only taken a few night shots. mono pod was to unstable so i propped myself and camera against the wall. 2x 14 shot bursts made then another 1x 5 shot burst. here was the final product after stacking in registax ( no darks used ), a full size and a cropped version. settings: F5.6 @ 300mm exposure time 1/125sec Iso 200 Auto WB
  14. Should i be polar aligning my tabletop heritage 76mm dob telescope. and how can one do this. i am also trying to work out how i can add ALT/ and DEC markings to my scope, this will help me find my stars and points of interest more faster. i live in a medium dark area, but still polluted by street lights and the large city, so i only see the very bright stars at night. How do i go about marking telescope with ALT/DEC markings so i can use these instead of guessing where scope is pointing.
  15. Hi starlight, just outside Norwich here. have put a couple pictures up in the lunar ( image section ) and over in the DIY part a quick guide on converting my HD webcam thanks again for the welcomes Tami
  16. You need: HD-5000 lifecam (omnivision OV9712 Cmos chip ) 720p 1x 35mm film canister in black a cheap/old project box ( maplins etc etc) some glue and an hour or so in time Pic 1: this shows the webcam minus its flashy front covering, i removed this covering lifting a corner and peeling back. this uncovers two screws holding the cameras two parts together. take these out. Pic 2: now we have split the two halves. the front half holds the cameras mic and ground cable. the rear half holds the PCB, on the left side is the camera usb connection, to the right the mic's connection. to get the cable out from rear case, use a craft knife to scrape away the glue, then needle nose piers and twist/pull free ( remember to remove connections ) the cable and the clip type holder all comes away Pic 3: main board : here you can see i removed the lens after i forgot to photo it. red ring: the blue SM l.e.d covered with artists black paint, a couple coats should do. green ring : this is the + imput to the lens. if we de-solder/cut this the shoddy MS auto focus is disabled, (if used in a car ) green + blue ring: desolder both of these while lens is still fitted. we do not need these. unscrew the lens holding plate from the rearside of the board, slip off the rear chipset heatsink, to get to the two screws holding plate to pcb and place this into a container covered ( no dust on Cmos ) Now we pull the lens unit apart. pry of the metal cover from all four sides. pop this off. unclip the small plate holding lens in place, then pull out lens snipping coper wire connections. Keep stripping down until you have a single plate like above picture with a large'ish center hole. screw this back onto the pcb. mount your PCB board into your new camera housing. remember to cut out hole so light can hit the Cmos sensor. superglue and some plastic standoffs are ideal. plug in and test does the sensor see light and shadow. Pic 4+5 take your container lid and in the center drill out a hole the same size as hole in the lens plate you just fitted back to the board. glue this over the hole in your project box where your sensor fits. like in pic 5 next cut the bottom of your film can like in pic 5 and slip this into the container lid like in pic 4. leave the box for a good 2hrs or so, this lets the glue set and everything settle. Final product looks ugly, feels like a eggshell, but does the job just fine. Do Not install the microsoft drivers, allow WDM to take over. i found sharpcap to be perfect. sorry no long exposure here, and gain control is tied with brightness. thank you for viewing my BYW ( bash your webcam) conversion to astrocam Tami
  17. had the same problem with a converted webcam. could not get close enough to the focal plane. took me about 5 mins to work out that the eyepiece holder was the problem. removing this gave the camera the added few mm drop to focus perfect. was the most effective way to get camera and telescope to focus.
  18. Hi pete i have been having same problem but on a smaller scope, not enough in travel. i solved the problem by removing the eyepiece holder, this gave the the few mm needed for focusing. maybe give this a try see if it helps your problem.
  19. Thank you for the greetings am new to astronomy but not to tinkering, as my name may imply ( R/C car racing). i Cut my teeth for around 20yrs in the radio control toy area. from racing to truck conversions, flying heli's and general tinkering, body spraying and decal design. i was also an avid kiteboarder and extreme sports man, but as i become old my bones tended to snap and not bend. so astronomy , photography and gardening became my choice of hobby. i have already converted a cybershot point and shoot to false colour IR, and just finished converting a microsoft HD-5000 webcam to astrocam, i documented this on a different none astronomy site. but added a couple snaps of the moon here. a couple of many to come i hope. thank you again for the warm welcome to your community Tami
  20. Picture 1 : full Moon. Taken with a Fujifilm S2500 Bridge camera @ 504mm (35mm eqiv) this is the shot that inspired me towards astronomy. Picture 2 : Moon HDwebcam my little 76mm /300mm dob @ f3.9 , this is my latest shoot. i used my converted HD webcam. seeing was very bad it looked like heat haze. 180MB AVI 309 frames stacked. camera has no IR filtering so image is converted to greyscale please leave comments, advice and a general dig. they not the best but i learn for mistakes and advice and hope to become a better photographer Tami
  21. Hello, my name is Paul, but most call me Tami. i am just touching 40 yr old, and am a amateur Photographer. around a year ago i purchased my first digital camera, and captured my first ever lunar photograph. Ever since i have been hooked. i traded my camera in for a second hand DSLR. Fast forward to about a month ago, i purchased my first ever telescope. after a couple nights viewing, i wanted more that the telescope could give me. i have already converted a couple of cameras to Infrared. About three Days ago i converted a Microsoft HD-5000 webcam into one i could use with telescopes and have not looked back. the tools of my trade are : Canon 350D with Ef-s 18-55mm and a canon EF 90-300mm. modded HD 720p webcam Sky Watcher heritage 76mm / 300mm table telescope. thank you for reading and your greetings Tami
