Planetary Nebula targets

Recommended Posts

Posted (edited)

I have a small 60 deg prism which sits over the eyepiece, similar to that used by Hartung. This is ideal for separating a small planetary from stars in the FOV.

The stars show a small spectrum, the planetary shows as a steady spot.

simple and easy to use.

I found that one- I don’t know why I expected it to but it didn’t blink at me- I was quite disappointedI! I wasn’t doing it right though- didn’t realise you had to use a special technique to get it blinking 🤦‍♂️ next time...

Likewise, I’ll have to give it another go with the correct technique because it didn’t blink for me

I stand no chance of finding IC3568. I can't even find it on skysafari. However I type it in the search it just says item number not found?!

Try putting a space between the IC and the numbers....... or finding if it has another classification... like a PN  number.... Abell .... Sharpless object.....?? etc

Google-time....

There you go.... try these....

IC 3568, PK 123+34.01, UGC 7731, PN G123.6+34.5, ARO 56

Which version do you have? Mine is the Pro, with all the extra databases so it may just not be in there. I would have thought it was in Plus though, not sure.

This might explain it Stu. I think I have the basic which is what I downloaded when I 1st started out. I will have a look at the upgraded versions!

Worth waiting till they have their next special offer which they quite often seem to do Baz- I think I got my pro half price. I thought I got the add on databases too but seemingly not- the in app purchase can’t have worked so I’m waiting for them too

Yes you will need the Pro version. The basic version does leave a lot out. Haven’t used SkySafari in a while though since switching to Luminos.on the iPad.

That’s a good point Mark, if you can wait there is a decent saving to be had. Plus is cheaper and says it contains the entire NGC and IC catalogue so is pretty comprehensive. The only benefit to Pro is the extended catalogues; the main reason I have it is curiousity so I can check out anything I see referenced elsewhere. I’m pretty sure most of what I will ever observe will be in Plus. The only gripe is that you can’t upgrade, you have to buy Pro at the full (or half) price if you want it after getting Plus. It’s a fabulous app though, the best there is in terms of content, features and scope control.

The OIII filter is definitely a string to your bow regarding the accessories in your camera case. It can make or break on certain objects visually, and in the scheme of things it comes down to seeing conditions as we would all love sky bortle rating 1,2 skies. However, if I can do without using the Olll filter I will, as on most planetary nebula contrast and detail are lacking, even though image brightness is improved and is a must to actually see on certain objects. Initially I will use the filter to distinguish the object in the field of view, first putting a blanket over my head however crazy that may seem (who cares anyway, usually on your own in the dark) as if I can help it, I would rather see an object in its more natural form. From my experience even though O111  filters are great at times visually, at times it can just show a brighter blob on some planetary nebula targets.
