Love the veils! What camera did you use to take that as it is on my hit list and I was wondering about how frame it. Ta

Thanks! Original unmodded A7s with an H-alpha/OIII dual-band filter (L-Enhance).

The sky was clear the other night apart from an 85% full moon, so I tried out the 61EDPH with the Altair Quadband filter and the Altair Hypercam 269c on the North America Nebula. Lots of compression here. I am going to put some full res stuff on astrobin for this scope.

Here’s another Veil. Taken with a 1600mm in HO with only 3hrs of integration time. Need to tweak the spacing just a tiny bit.

I've put high res versions of my recent shots with this scope on astrobin.  There are a couple of others on this link, and probably some more coded differently if you dig around:

Is there any 1.0x flattener compatible with sharpstar 61?

None by the manufacturer. I get you don't want to lose any focal length.

Yes. 275 will be too wide smile.gif

I’ve tested the Hotech SCA (which is optically identical to the Orion flattener and some others) and it does not work very well.

I believe these manufacturers should be making 1x options

As I understand it a filter can screw into the Flattner, that is 2" correct?

YES a M48 filter will thread inside of the 0.8 reducer.

You may want to see if the William optics 61A flattener would work... it is a 1.0X but requires a M54 thread to mount onto the scope and has an internal 2" filter screw mount with M48 out for t-ring.

It fits onto the Zenithstar 61 v2 scope.

The Sharpstar has M63 thread, meaning that a step down adapter of M63 - M54 might be required. I don't how that might play out.

Had a few clear nights this week, so stayed on IC1396 for almost 24h in SHO. Moon gradients are pesky to correct, but really enjoyed seeing the image build up on the Asiair pro's Live stacking interface. Full version: https://www.flickr.c...yan/50439447656

TS optics make an M63 to M54 adapter. That’s what I used to test the Altair flattener. I guess I’d need a loan WO to try out!

I'm late to this thread...but what adapter piece do you use to connect your canon to the sharpstar?

M63 to M48 or to M42, depending on the thread size of your t-ring.

But if you want to use 2" filters, the standard size it M63 - M48. That was what the seller sent to me a bonus.

Thanks! This is the T Ring I have...How would you determine with M size?

That one won’t work since it’s M42. You want a M48 t-ring. If it says M42 or T2, it will not fit the Sharpstar’s reducer.

Hope I'm not completely hijacking this thread, but I see one here:

So once I have this, and the Sharpstar, is there any other connectivity pieces I need?

Nope, but I would consider some thin spacers to tune the spacing.
