    Default Skywatcher Heritage-100P



    Skywatcher Heritage-100P - First Light Optics

    Hello all, question one as promised in my introductory post! Anybody had a play with one of these yet. I am seriously thinking of getting one as an instant grab n go scope. Simple to set up and minimal cooling.

    Points of interest that I am unsure about is what is the maximum anyone has taken it too. (I realise the theoretical is x200) and does the base disassemble easily? (thinking for holidays)

    Yes, I have. In the U.S., Orion Telescopes and Binoculars markets this scope as the Orion SkyScanner. Exactly identical. Very light and portable - fits in a medium-sized backpack.

    Wow - at 97-114£, it's much more expensive in the UK than in the U.S. But then I see it comes with a 2x Barlow lens, which is not included in the package over here, where it sells for about 72£ ($119.95), not including tax.

    One problem is that the primary mirror isn't collimatable. So I unscrewed the rear end of the scope, center-spotted the primary mirror, then screwed it back on. I then collimate the scope by adjusting the tilt of the secondary mirror by fiddling with the three allen-head screws on the secondary holder until the secondary is aligned with the primary (by looking through a collimation cap attached to the focuser).

    Once collimated, gives good views of the planets and double stars. I've maxed it to about 133X (6mm EP + 2X Barlow). But probably better for deep-sky objects - use it away from the city lights, and you'll be able to pick up a lot of deep-sky stuff with it, thanks to it's generous 100mm aperture for such a compact scope. All the Messier objects will be visible in darker-sky conditions (except maybe for some of the more southerly Messier objects from your latitude).

    Thanis terrynak. I will be happy with x133 tbh.

    if clouds are kind tonight I am going to give it a try out and first thing will be to push the mag on jupiter just to see. Then I will try a few dso starting with M45 to see how good the wide field, low mag views are, then hyades and onto M42 and M35 abd I think diubke cluster abd finally andromeda.

    from my lp, s gareen thats the limittions I am afraid but one of the reasons I am getting this is for snatch and go mini sessions, holidays and superwide fields views. Think its 3.5 degrees with the 25mm in at x16.

    qll mapped oit, now its just hoping weather is kind, oh, erm :/

    Planets are hugely dependent on seeing conditions, so on most nights, don't expect good views of Jupiter at 133X with this scope. Also depends on how well collimated the scope is - at F/4, collimation is critical.

    Have you gotten this scope already?

    Yes I already have it terry and first thing I did was to collimate it. Was pretty easy doing as you did above. It was only very slightly out but spot on now. Gave it a brief first light the other night and thus far I am very impressed.

    I have a Celestron Xcel barlow to use instead of the stock one and I have got a TMB 8mm and BST 6mm to use with it also. Can't see me using the 10mm much use in favour of the 25,8 and 6 plus barlow

    Awesome! I'm glad you were able to optimize this scope with a minimum amount of fuss.

    This was my workhorse for 3 years, despite getting some bigger (and smaller) scopes along the way. Couldn't be beat in terms of portability.

    Used it with a heavy-duty Manfrotto tripod. Removed the 1/4-20 UNC adapter that is inserted in the thread at the bottom of the base, so that I could accomodate the more substantial tripod with a 3/8-16 UNC screw.

    Mainly used the two Kellner EP's (20 and 10mm) that came with it, along with 26mm and 7.5mm Plossls and a 2X Barlow to reach higher magnifications.

    Although no longer my main observing scope, I will still use it when a lightweight backpack scope with 100mm of aperture is required.

    It is a little cracker no doubt. I have decided against getting a mount as this is mainly going to be used in the back garden for mini sessions and holidays stuck on a table top.

    I have bought a cheap 2ft x 2ft folding table that is the perfect height and very light so can throw it around easily on the patio (not literally o/c ) and in conjunction with my viewing chair should be great for mini sessions.

    You see often in UK its a case of gap in the clouds for an hour, lets go, not always worth getting out a 12 dob for that. this however is ideal

    I'm a small scope user (apertures of 6" or less), prefer portable scopes that I can carry on foot (I don't have a car) to get away from urban skies. Which is why this was my main scope for a few years.

    Well, we've been having wet/cloudy weather the past few days here in L.A., but during those few hours where there have been a break in the clouds, I've been testing my newly purchased old Meade 60AZ-T (60mm F/5.8 scope) from Ebay (discontinued model, the date on the manual says 2005).

    Originally came with a tabletop tripod; here I have it mounted on a Celestron Astromaster Alt-Azimuth tripod. Views are much improved once the prism diagonal is replaced with a mirror star diagonal. Can't wait to test this out away from urban skies, see how many DSO's I can pick up using 2.4" of glass.

    How does this compare optically etc. with the ubiquitous ST80 (Orion, Skywatcher etc. all have a version - AFAIK they're all the same OTA made by Synta)?

    I have one that I either put on a little tabletop EQ1 or a photo tripod to take away for travel/camping and I'd have to say it's merely "OK" for me. I think I'm spoiled by the views I get from my 8" dob but the CA produced by the ST80 is off-putting on the moon and planetary targets, and I think it's just too small to gather that much light for most DSOs unless you're under exceedingly dark skies.

    This new 100P looks like a great potential replacement - can anyone comment on how its larger aperture compares with the ST80s on the same targets - its focal length is like-for-like (allbeit its ratio is slightly faster)?

    Since the secondary is so large compared to the overall aperture, I worry that it obstructs the lightpath too much so that the extra 20mm it has over the ST80 isn't really that noticeable?

    Also, can the base be deconstructed simply to be transported slightly more easily?

    I have had a ST80 and the 100P is far superior especially at higher mags.

    The base comes apart simply and will be travelling to the Dominican Republic in 4 weeks for my honeymoon. Hope the wife doesn't mind, haha
