  1. just to support what John is saying, i have done this. i bought a 300p auto and then a 1145p AZ goto (second hand) and swapped the handsets after upgrading the firmware to 3.07. currently find it nice having a small scope and the bigger dob as i`ve ended up setting up both scopes small tracking the moon (bright stuff) and the bigger looking at deep sky etc
  2. hi there i have a 300p flex auto with the goto handset, works well and can be connected to a PC (although i haven`t tried as yet). i would say that the goto isnt as accurate as a EQ mount but the dob is very easy to live with setup is very quick and mines on wheels which makes things easy on the arms. you do have to colminate every time but i still get ok results when i havent bothered. if your in to the getting in to the deep sky stuff i would suggest getting a samsung sdc-435, allows you to see the fuzzy stuff in colour live and M42 looks really good. the camera increases what you can see ge
  3. I have now bought the SCB-2000 being the rebadged 435. I`m using it on a skywatcher 300p Dob and have a 0.5 reducer on the front. I bought a 17" lcd tv second hand for the back garden and powering everything from a power unit with two 12vdc outs and a built in 240vac inverter (from Makro) I had quite a few problems achieving focus using the reducer as I cant get the focusser to move in enough, so in the end i`ve removed the reducer. I spent a bit of time on the moon the other night to get used to various setting etc and then moved on to other object again which has helped, although im at a mag
  4. Many thanks for the reply, will have a play with the EP eye cup position theres also a few nasty chrome screws in my scope so will try and cover them up. Does anyone out there no where to get flocking material (in the uk) please?
  5. Hi Will I have a auto Dob that i`ve used the handset from a Goto 1145P on and it works fine. It looks like things can be exchanged as long as the hand set it AZ based, i end up upgrading the firmware off the skywatcher site aswell.
  6. After buying a 4mm TMB and a 12mm ED explorer I have found i seem to have a bright object flittering around in my scope. Was looking at saturn at the time at around 250-375 mag, using a 300P skyliner flextube. wondering if this is a internal light reflection issue or a eyepiece issue? any suggestions? (by the way the EP`s are great compare to the standard Skywatcher ones!)
  7. just found this might be of use, especially the star check looks really good stuff Astro Babys Guide to Collimation
  8. Hi John, as you`ve bought a power tank not sure this helps but... my skywatcher has a 2.5mm supply plug being tip +ve, which i think is a common connector for scopes (if not dont read on, sorry). i went to makro and looked at their 12vdc power tanks (car jump start units) and got a unit for £29 ish which has a 2.5mm to cigar socket lead to allow you to charge from a car outlet, but you can also plug it in to the 12vdc outlet on the power tank to power a scope. There is also a 240vac to 2.5mm charger that is enough to power my dob via the mains. (in the end i bought another unit from makro that
  9. Hi Space cowboy, you almost certainly know this already but... i have to finish aligning on a target using the up and right direction controls, to get tracking to work. on my scope there a lot of play between the up and down drive so if i finished on the down, the gears have to use up the slack before tracking the object. i take it the scope will drive manually up in slow speeds using both hand controls? and you have used a good power supply? not sure if you can do this while tracking, but the goto handset lets you see the encoder positions under "show position", you could look at this durin
  10. I have been planning to do the contrast improvements, but with the scope being new didn`t want to void any guarantee on the OTA. have seen this thread, http://stargazerslounge.com/equipment-discussion/99482-improving-flextube-contrast.html do you just use matt black paint on the screws and secondary? Will try to take some photos and stick them on here but the set up is all fairly standard with the astrozap shroud and wheels on the base (the wheels are great makes using the scope alot more usable)
  11. could it be dew? Had another look in the scope last night and couldn`t see anything on the primary, when in a warm area. planning to have a look at the primary when theres a chance for dew to build up. wondering if theres some sort of residue present that dews up quickly in some area, being the smeer i`d seen before. thinking of this terms of swimming goggles misting up, wash them out with "fairy" and then no more misting. did have a look for dew on the night of comparison and couldn`t see anything using a red head torch down the scope. Hoping that its just a dew issue and i`ll do another c
  12. Its new, as in less than a month old. when i built it up the primary had a bluish smeery look, this was the very first peek at the mirror after taking off the dust cover. I thought that it might be something from when the scope was packed as in a cleaning agent that once the scope was open to atmosphere it would evaporate. having thought about this further im wrong as the mirror isnt sealed its open around its mounting. i had in my head that this would be a seal space until the dust cap was removed as its quite a good fit and then the scope packaging would seal everything else up. Hence need
  13. When doing the comparison i put a 25 in the 12" being, 1500/25=60 mag then in the 4.5 put a 10mm, 500/10=50 i could only see a bit more detail in the gas clouds Im must admit i am a bit worried something is wrong, but the mirrors look clean and have aligned using the laser, and then defocussing a star in the middle of the EP gives a fairly even field (no comet trails) There was a slight wash effect on the primary when i first built the scope up, however thought it was a cleaning agents that would evaporate. cant see this now in daylight but i was concerned at the time not sure what else to do
  14. Thanks John, i think i`ll have a try at M51 next time the skies are clear, will do a compare using the 4.5" and 12". was also looking to try the bigger nebula e.g M42, M31, M8 Any big nebula recommendations?
  15. skies are fairly dark where i am as we`re not near any large town etc. Im thinking that i should see a massive difference between a 4.5" to my 12" on something like M42, currently is not worked out that way any pointers?
