  1. A lot of love for the 150P I see. Having had a gander Im very tempted by it, too. Im still a bit confused with the difference between the two. What I mean by that is that I understand that one is longer than the other, longer focal length and hence more magnification and contrast; but doesnt that mean that essentially Id end up looking at a slightly larger coloured blob? Which version should I go for if assuming I primarily look at deep sky objects? Scope aside, are there any other accessories I should be looking for besides a moon filter, collimation aid, LP filter(?) and a red pen torch? Also, blumming hell at an EQ3 motor drive! £75 compared to the EQ2 which is about £30. I understand that its got to swing a larger mass around, but its still a fair chunk of money. :/
  2. Hello all. Further to my previous single post ( I asked about the differences between skywatcher and celestron 5" reflectors) I thought Id ask a few more questions since I want to get the best I can for the little money Ive got. Despite lurking for a while I still havent formed an absolutely concrete opinion on a scope, which is where I thought you guys could help me out. My situation is currently this: Im a penniless student with about £200 guaranteed and an undisclosed, barely discussed amount from parents (but as a ballpark, say about £150), who are probably going to fork over as an early christmas/birthday gift. Im not concerned with GOTOs seeing them as a cash sink that could be better spent on optics; and since I dont have a car a dobsonian or other massively clunky device is out. Storage space is also a bit of an interesting challenge. Ideally I'd like a bit of money left over for maintenance equipment if i need it (like collimation gear). With this in mind, I've got a few questions. 1) Its apparently widely accepted that the budget entry into the field is a five inch reflector, but from what Ive seen of late in astronomy now and sky at night it seems that small maksutovs (celestron nexstars mainly) are starting to become more popular and more pushed by retailers. Is there any real advantage of the maksutov over a newtonian? I plan to observe a bit of everything; nebulae, planets and galaxies for visual interest and trying to find variable stars and other things for the scientific interest. Should I stick with a newtonian or go for a small mak? 2) In a similiar vein, I noticed the skywatcher 130PM has been discontinued recently, and this has caused a bit of an outcry. However what Ive been able to find out indicates that a spherical over a parabolic mirror at 5" of aperture isnt the end of the world that people think it is. OR is it? I realise this is a challenge, and especially for ~£350, but I thought I'd throw down the gauntlet. Thanks for your help!
  3. Hello gents and ladies. Ive been toying for a while now with the idea of getting a scope and taking the plunge into amateur astronomy as a (fairly serious)hobby, and Id like to ask a question about the likely scopes. My budget as a student is pretty low, probably an all-up cost of about £200 max. As Im sure everyone is going to start screaming at me, this means pretty much the 130mm Skywatcher reflector, with or without motor drive (admittedly Im pondering whether to go with or without since if without that lets me spend a little more on accessories like additional eyepieces, which seems to be the going advice to the newcomers). And this is the thing. Is there really that much of a difference between the Skywatcher 130mm and the Celestron 130mm equivalent model? Most of the time I see the Skywatcher has a slightly higher price, but the cynic in me says that a chunk of that is due to the endorsement by Sir Patrick. I fail to see just what magical foibles that Skywatcher could bolt onto this thing to make it worth that extra twenty quid. Any advice/opinions appreciated. Thanks!
