  1. Hi,

    I love this nebula but haven't imaged it before, would like to give it a go this winter. 

    However, for my FL (430mm) on my Z73 it doesn't fit in well so I'm going to be using my 55-250 at 250mm. Will a heater band around the lens hood keep the lens clear? If not should I even bother using the lens hood and instead just wrap it around the lens element and focus ring?

    Am I right in thinking that this should be a good target with a stock DSLR as it's a reflection nebula.

    I imagine I'm going to need a lot of subs to reveal this faint target, but I don't mind ploughing in a fair bit of integration time.

    Any advice appreciated.

    Actually I could use my refractor I think, I'd have to go for a portrait shot but it fits in quite nicely.

    The only thing is it'll really take some work trying to frame it and then see if it's in the shot, guess I'll have to open a sub in PS and stretch to see if I've got the nebula!

  2. Hi,

    I have been imaging deep sky objects for a good couple of years now and would like to start looking through my telescope as well.

    What do I need? I have a Zenithstar 73 scope and HEQ5 Pro. What do I need to buy and attach to the scope so that I can look through it and what should I be able to see in terms of dso's etc.? I have bortle 5 skies..

    Thanks for any help.

  3. Superb, probably my fav nebulas, the HH & Flame. I love both images, with and without stars. 

    Without it's definitely easier to focus on the clouds and gasses and look at the structure and detail but both great. 

    Images like this completely remove the idea of upgrading to an OSC (from DSLR) out of the question. I'd imagine there's no way can you get this level of detail in an OSC given the same integration time and Ha filter.

  4. Hi

    I've only used my 50mm 1.8 lens once for astrophotography for a cygnus widefield shot, but that was in the Summer when I didn't need to use dew prevention.

    I'm just wondering how to keep the lens from dewing up on a frosty night as where the focus ring would be covered by a dew band or is not a problem ?

  5. Hi,

    I've uploaded a video to my astro channel which I thought may be of some help to beginners in the hobby. 

    After I'd bought my HEQ5 I needed to figure out how to power it and what I needed to buy and so this video explains what equipment and power I use to run everything off the mains supply.

  6. Funnily enough I've just sent you an email 2 minutes ago Steve, asking if the strap is covered under warranty. 

    I ordered it from you in October 2018. 

    Not sure why it happened but from posting how I connect my equipment together and the replies it seems to me that I'm connecting things ok.

    I also noticed the cable itself getting very warm when connected, compared to the cable I've only just ordered from you this week (the 2" version) which was cold to the touch when in use.

  7. Hi,

    I need some help please!

    I've been running my imaging rig quite happily for some time now but I had to order a 2" dew strap for my guidescope the other day.

    So today I connected everything up and connected the new guidescope strap.

    Whilst setting up, and fortunately I noticed it whilst I was setting up and not in the house, my telescope dew strap (4") started emitting some wisps of smoke. Luckily I realised it wasn't my breath under my head torch and was indeed smoke, then I noticed a small orange flame lighting up where the cable goes into the heater band. 

    It's melted that part of the cable.

    Something a bit awry with power and amperage then I assume. 

    I run my rig off the mains. So I have an extension cable from the house (going into an RCD adapter) out into my dribox into a 4 way plug extension socket. 

    Plugged into the 4-way is a 240 Mains to 12V voltage converter. Then I have this 12v multisocket thing below and then a hitec astro 2 port dew controller plugged into that (also below)

    So what's a better and safer way of connecting my dew straps to something?

     

    Here's what I have....
